In the wake of the South Sea Bubble financial crisis, Walpole became First Lord of the Treasury and Chancellor of the Exchequer.

He never held the title 'Prime Minister,' but was given the powers that came to be associated with the office. George I also gave him 10 Downing Street, still the official residence of the prime minister.

George IIexercised little control over British domestic policy, which was largely controlled by the Parliament of Great Britain. As elector, he spent twelve summers in Hanover, where he had more direct control over government policy.

During the War of the Austrian Succession, George participated at the Battle of Dettingen in 1743, and thus became the last British monarch to lead an army in battle. In 1745, supporters of the Catholic claimant to the British throne, James Francis Edward Stuart ("The Old Pretender"), led by James's son Charles Edward Stuart ("The Young Pretender" or "Bonnie Prince Charlie"), attempted and failed to depose George in the last of the Jacobite rebellions.

The flying shuttle was patented by John Kay in 1733. Its adoption would revolutionize the British textile industry and, in no small part, help spark the industrial revolution. Its basic design was improved over the following years with an important one in 1747

Joseph Priestley was a renowned English theologian, author, chemist and political theorist of the 18th century. He is also regarded by many as the one who discovered oxygen. His contribution to science was so immense that he had been made a member of nearly every major scientific society by the time he passed away

James Watt was a Scottish inventor, mechanical engineer, and chemist who improved on Thomas Newcomen's steam engine with his Watt steam engine in 1776, which was fundamental to the changes brought by the Industrial Revolution in both his native Great Britain and the rest of the world.

While working as an instrument maker at the University of Glasgow, Watt became interested in the technology of steam engines. He realised that contemporary engine designs wasted a great deal of energy by repeatedly cooling and reheating the cylinder. Watt introduced a design enhancement, the separate condenser, which avoided this waste of energy and radically improved the power, efficiency, and cost-effectiveness of steam engines.

Watt attempted to commercialise his invention, but experienced great financial difficulties until he entered a partnership with Matthew Boulton in 1775. The new firm of Boulton and Watt was highly successful and Watt became a wealthy man.

Spencer Compton, 1st Earl of Wilmington, KG, PC was a British Whig statesman who served continuously in government from 1715 until his death. He served as the Prime Minister from 1742 until his death in 1743. He is considered to have been Britain's second Prime Minister, after Sir Robert Walpole, but worked closely with the Secretary of State, Lord Carteret, in order to secure the support of the various factions making up the Government.

Henry Pelham was a British Whig statesman, who served as Prime Minister of Great Britain from 27 August 1743 until his death.

Pelham's premiership was relatively uneventful in terms of domestic affairs, although it was during his premiership that Great Britain experienced the tumult of the 1745 Jacobite uprising. In foreign affairs, Great Britain fought in several wars. Upon Pelham's death, his brother Newcastle took full control of the ministry.

Edward Cornwallis arrived in Chebucto harbour in advance of 2,567 settlers. Work began on the town of Halifax, which replaced Annapolis Royal as the capital of Nova Scotia and established a strong British foothold in Nova Scotia.

Highland Clearances: from the 1750s, landlords in the Scottish Highlands began to forcibly remove tenants from their land, usually to replace them with more profitable sheep farming. The clearances resulted in whole Highland communities leaving Scotland and emigrating, most of them to North America. Many others moved to growing urban industrial centres such as Glasgow

Sir Joseph Banks was an English naturalist and botanist whose work paved the way for future-botanists. After inheriting a vast family fortune he could chase his passion, and went on to explore previously uncharted territories. He embarked on a voyage with James Cook aboard HMS Endeavour and returned with a major collection of specimens.

Banks advocated British settlement in New South Wales and colonisation of Australia, as well as the establishment of Botany Bay as a place for the reception of convicts, and advised the British government on all Australian matters. He is credited with introducing the eucalyptus, acacia, and the genus named after him, Banksia, to the Western world. Approximately 80 species of plants bear his name.

Thomas Pelham-Holles, 1st Duke of Newcastle upon Tyne and 1st Duke of Newcastle-under-Lyme, was a British Whig statesman, whose official life extended throughout the Whig supremacy of the 18th century. He is commonly known as the Duke of Newcastle. Historian Harry Dickinson says that he became, "Notorious for his fussiness and fretfulness, his petty jealousies, his reluctance to accept responsibility for his actions, and his inability to pursue any political objective to his own satisfaction or to the nations profit ... Many modern historians have depicted him as the epitome of unredeemed mediocrity and as a veritable buffoon in office."

Acadian delegates who refused the oath of allegiance were dispersed from Minas, and over the next few months most of the Acadian population of Nova Scotia was rounded up and transported away. About one half of the Acadians perished.

William Cavendish, 4th Duke of Devonshire, styled Lord Cavendish before 1729 and Marquess of Hartington between 1729 and 1755, was a British Whig statesman and nobleman who was briefly nominal Prime Minister of Great Britain. The Seven Years' War was going badly for Britain under the leadership of the Duke of Newcastle and when he resigned in October 1756, George II eventually asked Devonshire to form an administration. Devonshire accepted on the condition that his tenure would last only until the end of the parliamentary session. Devonshire believed his duty to the King required an administration capable of prosecuting the war successfully.

Thomas Pelham-Holles, 1st Duke of Newcastle upon Tyne and 1st Duke of Newcastle-under-Lyme, was a British Whig statesman, whose official life extended throughout the Whig supremacy of the 18th century.

George III was the third British monarch of the House of Hanover, but unlike his two predecessors, he was born in Great Britain, spoke English as his first language, and never visited Hanover. His reign was marked by a series of military conflicts involving his kingdoms, much of the rest of Europe, and places farther afield. Early in his reign, Great Britain defeated France in the Seven Years' War, becoming the dominant European power in North America and India. However, many of Britain's American colonies were soon lost in the American War of Independence. Further wars against revolutionary and Napoleonic France from 1793 concluded in the defeat of Napoleon at the Battle of Waterloo in 1815.

Later in life, George III had recurrent mental illness. After a final relapse in 1810, a regency was established, and George III's eldest son, George, Prince of Wales, ruled as Prince Regent.

John Stuart, 3rd Earl of Bute, was a British nobleman who served as Prime Minister of Great Britain from 1762 to 1763 under George III.

Bute's premiership was notable for the negotiation of the Treaty of Paris (1763) which concluded the Seven Years' War. In so doing, Bute had to soften his previous stance in relation to concessions given to France, in that he agreed that the important fisheries in Newfoundland be returned to France without Britain's possession of Guadeloupe in return.

George Grenville (14 October 1712 – 13 November 1770) was a British Whig statesman who rose to the position of Prime Minister of Great Britain. Grenville was born into an influential political family and first entered Parliament in 1741 as an MP for Buckingham. He emerged as one of Cobham's Cubs, a group of young members of Parliament associated with Lord Cobham.

His government tried to bring public spending under control and pursued an assertive foreign policy. His best known policy is the Stamp Act, a common tax in Great Britain onto the colonies in America, which instigated widespread opposition in Britain's American colonies and was later repealed.

An ally of the French, Ottawa chief Obwandiyag, whom the English called Pontiac, began a series of raids against English forts. Their attempt to drive the English away from the area killed both soldiers and settlers.

Charles Watson-Wentworth, 2nd Marquess of Rockingham, was a British Whig statesman, most notable for his two terms as Prime Minister of Great Britain. He became the patron of many Whigs, known as the Rockingham Whigs, and served as a leading Whig grandee. He served in only two high offices during his lifetime (Prime Minister and Leader of the House of Lords), but was nonetheless very influential during his one and a half years of service.

Rockingham's administration was dominated by the American issue. Rockingham wished for repeal of the Stamp Act 1765 and won a Commons vote on the repeal resolution by 275 to 167 in 1766. However Rockingham also passed the Declaratory Act, which asserted that the British Parliament had the right to legislate for the American colonies in all cases whatsoever.

William Pitt, 1st Earl of Chatham, (15 November 1708 – 11 May 1778) was a British statesman of the Whig group who led the government of Great Britain twice in the middle of the 18th century. Historians call him Pitt of Chatham, or William Pitt the Elder, to distinguish him from his son, William Pitt the Younger, who also was a prime minister. Pitt was also known as The Great Commoner, because of his long-standing refusal to accept a title until 1766.

Pitt is best known as the wartime political leader of Britain in the Seven Years' War, especially for his single-minded devotion to victory over France, a victory which ultimately solidified Britain's dominance over world affairs. He is also known for his popular appeal, his opposition to corruption in government, his support for the colonial position in the run-up to the American War of Independence, his advocacy of British greatness, expansionism and colonialism, and his antagonism toward Britain's chief enemies and rivals for colonial power, Spain and France.

James Cook led an expedition on HMS 'Endeavour' to observe the transit of Venus from Tahiti. The voyage continued into the South Pacific, where Cook circumnavigated New Zealand and charted the east coast of Australia. His team of botanists & scientists brought back many important specimens & much scientific information. Cook made 2 further Pacific voyages and was killed on the 2nd of these.

Augustus Henry FitzRoy, 3rd Duke of Grafton, (28 September 1735 – 14 March 1811), styled Earl of Euston between 1747 and 1757, was a British Whig statesman of the Georgian era. He is one of a handful of dukes who have served as Prime Minister.

He became Prime Minister in 1768 at the age of 33, leading the supporters of William Pitt, and was the youngest person to have held the office until the appointment of William Pitt the Younger 15 years later. However, he struggled to demonstrate an ability to counter increasing challenges to Britain's global dominance following the nation's victory in the Seven Years' War. He was widely attacked for allowing France to annex Corsica, and stepped down in 1770, handing over power to Lord North.

Frederick North, 2nd Earl of Guilford, (13 April 1732 – 5 August 1792), better known by his courtesy title Lord North, which he used from 1752 to 1790, was Prime Minister of Great Britain from 1770 to 1782. He led Great Britain through most of the American War of Independence. He also held a number of other cabinet posts, including Home Secretary and Chancellor of the Exchequer.

North's reputation among historians has swung back and forth. It reached its lowest point in the late nineteenth century when he was depicted as a creature of the king and an incompetent who lost the American colonies. In the early twentieth century a revisionism emphasised his strengths in administering the Treasury, handling the House of Commons, and in defending the Church of England.

The weaving of cotton cloth was a major industry by the 1760s, with most of the labour provided by people in their homes. In 1771, inventor Richard Arkwright opened the first cotton mill at Cromford, Derbyshire. Spinning was carried out by his own patented machine. This was a big step towards the automation of labour-intensive industries and heralded the beginning of the 'Factory Age' in Britain

Boston Tea Party: In 1770, taxes on American Colony imports had been repealed on all except tea. In 1773, colonists disguised as Native Americans dumped chests of tea from East India Company ships into Boston harbour in protest against this levy. Tensions between the colonists and the British government escalated.

Back in Britain, the public scoff at the action, because it is common knowledge that for tea to be correctly brewed, the water has to be at boiling point, with milk and sugar added according to taste. However the Boston Tea Party achieved its aims and, to this day, in hotels across America, puzzled British tourists are served "Hot Tea" with water that was boiled sometime in the last couple of hours. To add to their confusion it is served with a slice of lemon instead of milk. Meanwhile their American cousins quaff a strange concoction called "Iced Tea." For this, and this alone, independence was essential to ensure peace and harmony.

The American Revolutionary War, also known as the American War of Independence, was an 18th-century war between Great Britain and its Thirteen Colonies (allied with France) which declared independence as the United States of America.

After 1765, growing philosophical and political differences strained the relationship between Great Britain and its colonies. Patriot protests against taxation without representation followed the Stamp Act and escalated into boycotts, which culminated in 1773 with the Sons of Liberty destroying a shipment of tea in Boston Harbor. Britain responded by closing Boston Harbor and passing a series of punitive measures against Massachusetts Bay Colony. Massachusetts colonists responded with the Suffolk Resolves, and they established a shadow government which wrested control of the countryside from the Crown. Twelve colonies formed a Continental Congress to coordinate their resistance, establishing committees and conventions that effectively seized power

American forces laying siege to Québec launched a desperate night attack. American general Richard Montgomery was killed as the attack was repulsed with heavy casualties. The French habitants had failed to support the Americans and Canada remained British.

The United States Declaration of Independence is the statement adopted by the Second Continental Congress meeting at the Pennsylvania State House (now known as Independence Hall) in Philadelphia, Pennsylvania on July 4, 1776. The Declaration announced that the Thirteen Colonies at war with the Kingdom of Great Britain would regard themselves as thirteen independent sovereign states, no longer under British rule. With the Declaration, these new states took a collective first step toward forming the United States of America. The declaration was signed by representatives from New Hampshire, Massachusetts Bay, Rhode Island, Connecticut, New York, New Jersey, Pennsylvania, Maryland, Delaware, Virginia, North Carolina, South Carolina, and Georgia.

The first United Empire Loyalists — 1,124 refugees from New England — arrived in Halifax, NS. Another 40,000 or so followed them to NS and to Québec. The immigration resulted in the formation of New Brunswick and Upper Canada.

Sir Humphry Davy, was a Cornish chemist and inventor, who is best remembered today for isolating, using electricity, a series of elements for the first time: potassium and sodium in 1807 and calcium, strontium, barium, magnesium and boron the following year, as well as discovering the elemental nature of chlorine and iodine. He also studied the forces involved in these separations, inventing the new field of electrochemistry. In 1799 Davy experimented with nitrous oxide and became astonished that it made him laugh, so he nicknamed it "laughing gas", and wrote about its potential anaesthetic properties in relieving pain during surgery.

He also invented the Davy lamp which allowed miners to work safely with flame based lamps in the presence of flammable gases. He joked that his assistant Michael Faraday was his greatest discovery.

The Iron Bridge is a bridge that crosses the River Severn in Shropshire, England. Opened in 1781, it was the first major bridge in the world to be made of cast iron, and was greatly celebrated after construction owing to its use of the new material.

In 1934 it was designated a Scheduled Ancient Monument and closed to vehicular traffic. Tolls for pedestrians were collected until 1950, when ownership of the bridge was transferred to Shropshire County Council. It now belongs to Telford and Wrekin Borough Council. The bridge, the adjacent settlement of Ironbridge and the Ironbridge Gorge form the UNESCO Ironbridge Gorge World Heritage Site.

William Petty, 1st Marquess of Lansdowne, (2 May 1737 – 7 May 1805), known as The Earl of Shelburne between 1761 and 1784, by which title he is generally known to history, was an Irish-born British Whig statesman who was the first Home Secretary in 1782 and then Prime Minister in 1782–83 during the final months of the American War of Independence. He succeeded in securing peace with America and this feat remains his most notable legacy.

In March 1782 following the downfall of the North Government Shelburne agreed to take office under Lord Rockingham on condition that the King would recognise the United States.

William Henry Cavendish Cavendish-Bentinck, 3rd Duke of Portland, (14 April 1738 – 30 October 1809) was a British Whig and Tory politician during the late Georgian era. He served twice as British prime minister, of Great Britain (1783) and then of the United Kingdom (1807–09). The twenty-four years between his two terms as Prime Minister is the longest gap between terms of office of any British prime minister.

During his tenure the Treaty of Paris was signed formally ending the American Revolutionary War. The government was brought down after losing a vote in the House of Lords on its proposed reform of the East India Company after George III had let it be known that any peer voting for this measure would be considered his personal enemy.

William Pitt the Younger (28 May 1759 – 23 January 1806) was a prominent British Tory statesman of the late 18th and early 19th centuries. He became the youngest British prime minister in 1783 at the age of 24. He left office in 1801, but was Prime Minister again from 1804 until his death in 1806. He is known as "the Younger" to distinguish him from his father, William Pitt, 1st Earl of Chatham, called William Pitt the Elder or simply "Chatham", who had previously served as Prime Minister.

The younger Pitt's prime ministerial tenure, which came during the reign of George III, was dominated by major events in Europe, including the French Revolution and the Napoleonic Wars. Pitt, although often referred to as a Tory, or "new Tory", called himself an "independent Whig" and was generally opposed to the development of a strict partisan political system. He led Britain in the great wars against France and Napoleon. Pitt was an outstanding administrator who worked for efficiency and reform, bringing in a new generation of outstanding administrators.

The Northwest Indian War took place between the United States and a confederation of numerous Native American tribes, with support from the British, for control of the Northwest Territory. It followed centuries of conflict over this territory, first among Native American tribes, and then with the added shifting alliances among the tribes and the European powers of France and Great Britain, and their colonials.

In 1795 the US ratified two treaties that recognized the changes in power. By the Treaty of Greenville, signed by President Washington on 22 December 1795, the northwest Native American tribes were forced to cede southern and eastern Ohio and various tracts of land around forts and settlements in Illinois Country; to recognize the US, rather than Britain, as the ruling power in the Old Northwest; and to surrender ten chiefs as hostages until all American prisoners were returned. Also that year, the United States negotiated the Jay Treaty with Great Britain, which required British withdrawal from the Great Lakes forts while opening up some British territory in the Caribbean for American trade.

Since 1718, Britain had transported convicts to its North American colonies, until this was ended by the American War of Independence. On 13 May 1787, penal transportation resumed with a fleet of convict ships from Portsmouth for Botany Bay. This marked the beginning of transportation to Australia. Between 1787 and 1868, when transportation was abolished, over 150,000 felons were exiled to New South Wales, Van Diemen's Land and Western Australia

George Washington (February 22, 1732 – December 14, 1799) was an American military general, statesman, and Founding Father who served as the first president of the United States (1789–1797).

He commanded Patriot forces in the new nation's vital American Revolutionary War and led them to victory over the British. Washington also presided at the Constitutional Convention of 1787, which established the new federal government. He has been called the "Father of His Country".

Washington wrote: "As the first of everything in our situation will serve to establish a precedent, it is devoutly wished on my part that these precedents be fixed on true principles." To that end, he preferred the title "Mr. President" over more majestic names proposed by the Senate. His republican precedents also included the inaugural address, messages to Congress, and the cabinet form of the executive branch.

Michael Faraday was a British scientist who contributed to the study of electromagnetism and electrochemistry. His main discoveries include the principles underlying electromagnetic induction, diamagnetism and electrolysis.

Faraday received little formal education but he was one of the most influential scientists in history. It was his research on the magnetic field around a conductor carrying a direct current that established the basis of the electromagnetic field. He also discovered the principles of electromagnetic induction and diamagnetism, and the laws of electrolysis. His inventions of electromagnetic rotary devices was the basis of electric motor technology, and it was due to his efforts that electricity became practical for use in technology.

As a chemist, Faraday discovered benzene, investigated the clathrate hydrate of chlorine, invented an early form of the Bunsen burner and the system of oxidation numbers, and popularised terminology such as "anode", "cathode", "electrode" and "ion." The SI unit of capacitance is named in his honour: the farad.

Charles Babbage was an English polymath. A mathematician, philosopher, inventor and mechanical engineer, Babbage originated the concept of a digital programmable computer.

Considered by some to be a "father of the computer", Babbage is credited with inventing the first mechanical computer that eventually led to more complex electronic designs, though all the essential ideas of modern computers are to be found in Babbage's analytical engine. His varied work in other fields has led him to be described as "pre-eminent" among the many polymaths of his century.

Parts of Babbage's incomplete mechanisms are on display in the Science Museum in London. In 1991, a functioning difference engine was constructed from Babbage's original plans. Built to tolerances achievable in the 19th century, the success of the finished engine indicated that Babbage's machine would have worked.

Alexander Mackenzie's party reached the Pacific via the Bella Coola River, the first explorer to complete the journey overland. Though a physical triumph, Mackenzie's achievement failed to provide the fur traders with a viable route.

Edward Jenner was an English physician and scientist who was the pioneer of smallpox vaccine, the world's first vaccine. The terms "vaccine" and "vaccination" are derived from Variolae vaccinae (smallpox of the cow), the term devised by Jenner to denote cowpox. He used it in 1796 in his "Inquiry into the Variolae vaccinae known as the Cow Pox," in which he described the protective effect of cowpox against smallpox.

Jenner is often called "the father of immunology", and his work is said to have "saved more lives than the work of any other human". In Jenner’s time, smallpox killed around 10 percent of the population, with the number as high as 20 percent in towns and cities where infection spread more easily. In 1821 he was appointed physician extraordinary to King George IV

John Adams (October 30 [O.S. October 19, 1735 – July 4, 1826) was one of the Founding Fathers of the United States. He served as the first vice president (1789–1797) and second president of the United States (1797–1801). He was a lawyer, diplomat, and leader of American independence from Great Britain.

He assisted in drafting the Declaration of Independence in 1776 and was its foremost advocate in Congress. As a diplomat in Europe, he helped negotiate the peace treaty with Great Britain and secured vital governmental loans. Adams was the primary author of the Massachusetts Constitution in 1780, which influenced the United States' own constitution, as did his earlier "Thoughts on Government."

The Franco-American War more properly known as The Quasi-War was an undeclared war fought almost entirely at sea between the United States and France from 1798 to 1800 which broke-out during the beginning of John Adams' presidency.

After the French crown was overturned during the French Revolutionary Wars, the United States refused to continue repaying its large debt to France, which had supported it during its own revolution. It claimed that the debt had been owed to a previous regime. France was also outraged over the Jay Treaty and that the United States was actively trading with Britain, with whom they were at war. In response France authorized privateers to conduct attacks on American shipping, seizing numerous merchant ships, and ultimately leading the U.S. to retaliate.

Thomas Jefferson (April 13, [O.S. April 2] 1743 – July 4, 1826) was a statesman, diplomat, architect, and Founding Father who served as the third president of the United States from 1801 to 1809.

The principal author of the Declaration of Independence, Jefferson was a proponent of democracy, republicanism, and individual rights motivating American colonists to break from the Kingdom of Great Britain and form a new nation.

Jefferson pursued the nation's shipping and trade interests against Barbary pirates and aggressive British trade policies. He also organized the Louisiana Purchase, almost doubling the country's territory. His second term was beset with difficulties at home, including the trial of former VP Aaron Burr. American foreign trade was diminished when Jefferson implemented the Embargo Act of 1807, responding to British threats to US shipping. In 1803, Jefferson began a controversial process of Indian tribe removal to the newly organized Louisiana Territory, and he signed the Act Prohibiting Importation of Slaves.

The census was introduced to help the government understand the country's demographic layout and better utilise the population in wartime. A census of England and Wales, and a separate one of Scotland, has been taken ever since on a ten-yearly basis, with the exception of 1941. In 1801, information was collected on a parish basis. It was not until 1841 that more detailed information was requested.

Henry Addington, 1st Viscount Sidmouth, (30 May 1757 – 15 February 1844) was a British statesman who served as Prime Minister from 1801 to 1804. He is best known for obtaining the Treaty of Amiens in 1802, an unfavourable peace with Napoleonic France which marked the end of the Second Coalition during the French Revolutionary Wars. When that treaty broke down he resumed the war but he was without allies and conducted a relatively weak defensive war, ahead of what would become the War of the Third Coalition. He was forced from office in favour of William Pitt the Younger, who had preceded Addington as Prime Minister.

The First Barbary War (1801–1805), was the first of two Barbary Wars, in which the United States and Sweden fought against the four North African states known collectively as the "Barbary States". Three of these were nominal provinces of the Ottoman Empire, but in practice autonomous: Tripoli, Algiers, and Tunis. The fourth was the independent Sultanate of Morocco.

The cause of the U.S. participation was pirates from the Barbary States seizing American merchant ships and holding the crews for ransom, demanding the U.S. pay tribute to the Barbary rulers. United States President Thomas Jefferson refused to pay this tribute.
