Main articles: Irish Home Rule bills, Partition of Ireland and Irish War of Independence
In 1912, the House of Lords managed to delay a Home Rule bill passed by the House of Commons. It was enacted as the Government of Ireland Act 1914. During these two years the threat of religious civil war hung over Ireland with the creation of the Unionist Ulster Volunteers opposed to the Act and their nationalist counterparts, the Irish Volunteers supporting the Act. The outbreak of World War I in 1914 put the crisis on political hold. A disorganized Easter Rising in 1916 was brutally suppressed by the British, which had the effect of galvanizing Catholic demands for independence. Prime Minister David Lloyd George failed to introduce Home Rule in 1918 and in the December 1918 General Election Sinn Féin won a majority of Irish seats. Its MPs refused to take their seats at Westminster, instead choosing to sit in the First Dáil parliament in Dublin. A declaration of independence was ratified by Dáil Éireann, the self-declared Republic’s parliament in January 1919. An Anglo-Irish War was fought between Crown forces and the Irish Republican Army between January 1919 and June 1921. The war ended with the Anglo-Irish Treaty of December 1921 that established the Irish Free State.[100] Six northern, predominantly Protestant counties became Northern Ireland and have remained part of the United Kingdom ever since, despite demands of the Catholic minority to unite with the Republic of Ireland.[101] Britain officially adopted the name “United Kingdom of Great Britain and Northern Ireland” by the Royal and Parliamentary Titles Act 1927. In 1948 a working party chaired by the Cabinet Secretary recommended that the country’s name be changed to the “United Kingdom of Great Britain and Ulster”.[102] However, after considering the potential problems this could cause with other Commonwealth countries especially with respect to changes to the King’s title, the prime minister did not favour the change and it was not made.[103]
Interwar era
Historian Arthur Marwick sees a radical transformation of British society resulting from the Great War, a deluge that swept away many old attitudes and brought in a more equalitarian society. He sees the famous literary pessimism of the 1920s as misplaced, arguing there were major positive long-term consequences of the war to British society. He points to an energized self-consciousness among workers that quickly built up the Labour Party, the coming of partial woman suffrage, and an acceleration of social reform and state control of the economy. He sees a decline of deference toward the aristocracy and established authority in general, and the weakening among youth of traditional restraints on individual moral behaviour. The chaperone faded away; village druggists sold contraceptives. Marwick says that class distinctions softened, national cohesion increased, and British society became more equal.
