9 Modern history of the United Kingdom

The United Kingdom of Great Britain and Ireland was a sovereign state that existed between 1801 and 1922. It was established by the Acts of Union 1800, which merged the kingdoms of Great Britain and Ireland into a unified state. The establishment of the Irish Free State in 1922 led to the country later being renamed to the United Kingdom of Great Britain and Northern Ireland in 1927, which continues to exist in the present day.

A subset of absolute idealism, British idealism was a philosophical movement that was influential in Britain from the mid-nineteenth century to the early twentieth century. The leading figures in the movement were T. H. Green (1836–1882), F. H. Bradley (1846–1924), and Bernard Bosanquet (1848–1923). They were succeeded by the second generation of J. H. Muirhead (1855–1940), J. M. E. McTaggart (1866–1925), H. H. Joachim (1868–1938), A. E. Taylor (1869–1945), and R. G. Collingwood (1889–1943). The last major figure in the tradition was G. R. G. Mure (1893–1979). Doctrines of early British idealism so provoked the young Cambridge philosophers G. E. Moore and Bertrand Russell that they began a new philosophical tradition, analytic philosophy.

The Edwardian era or Edwardian period of British history spanned the reign of King Edward VII, 1901 to 1910, and is sometimes extended to the start of the First World War. The death of Queen Victoria in January 1901 marked the end of the Victorian era. Her son and successor, Edward VII, was already the leader of a fashionable elite that set a style influenced by the art and fashions of continental Europe. Samuel Hynes described the Edwardian era as a "leisurely time when women wore picture hats and did not vote, when the rich were not ashamed to live conspicuously, and the sun really never set on the British flag."

Ireland was part of the United Kingdom of Great Britain and Ireland from 1801 to 1922. For almost all of this period, the island was governed by the UK Parliament in London through its Dublin Castle administration in Ireland. Ireland underwent considerable difficulties in the 19th century, especially the Great Famine of the 1840s which started a population decline that continued for almost a century. The late 19th and early 20th centuries saw a vigorous campaign for Irish Home Rule. While legislation enabling Irish Home Rule was eventually passed, militant and armed opposition from Irish unionists, particularly in Ulster, opposed it. Proclamation was shelved for the duration following the outbreak of World War I. By 1918, however, moderate Irish nationalism had been eclipsed by militant republican separatism. In 1919, war broke out between republican separatists and British Government forces. Subsequent negotiations between Sinn Féin, the major Irish party, and the UK government led to the signing of the Anglo-Irish Treaty, which resulted in five-sixths of Ireland seceding from the United Kingdom.

Margaret Thatcher gained power in 1979 and began 18 years of Conservative government. Victory in the Falklands War (1982) and the government's strong opposition to trade unions helped lead the Conservative Party to another three terms in government. Thatcher initially pursued monetarist policies and went on to privatise many of Britain's nationalised companies such as British Telecom, British Gas Corporation, British Airways and British Steel Corporation. She kept the National Health Service. The controversial Community Charge, used to fund local government was unpopular and the Conservatives removed Thatcher as Prime Minister in 1990.

The Industrial Revolution, now also known as the First Industrial Revolution, was the transition to new manufacturing processes in Europe and the United States, in the period from about 1760 to sometime between 1820 and 1840. This transition included going from hand production methods to machines, new chemical manufacturing and iron production processes, the increasing use of steam power and water power, the development of machine tools and the rise of the mechanized factory system. The Industrial Revolution also led to an unprecedented rise in the rate of population growth.

The Irish Free State was a state established in 1922 under the Anglo-Irish Treaty of December 1921. That treaty ended the three-year Irish War of Independence between the forces of the self-proclaimed Irish Republic, the Irish Republican Army (IRA); and British Crown forces.

The Second Industrial Revolution, also known as the Technological Revolution, was a phase of rapid standardization and industrialization from the late 19th century into the early 20th century. The First Industrial Revolution, which ended in the middle of 19th century, was punctuated by a slowdown in important inventions before the Second Industrial Revolution in 1870. Though a number of its events can be traced to earlier innovations in manufacturing, such as the establishment of a machine tool industry, the development of methods for manufacturing interchangeable parts and the invention of the Bessemer process to produce steel, the Second Industrial Revolution is generally dated between 1870 and 1914.
