Why did Ireland become a problem for the Government from 1910-14?

England was largely protestant but Ireland was predominantly Catholic. However the six counties of the North East (Ulster) were mostly protestant. In the 19th century Britain faced some opposition fro the limited Fenian Movement and a well developed political campaign for self government. By 1874 this had built up influence as a party of nationalism. Under Charles Stewart Parnell, the home rule movement developed into the Irish Nationalists who usually gained around 72 seats in elections. They held the balance of power in Westminster. However in 1886 and 1893, the Lords rejected the Liberals' Home Rule bills.

Conservatives joined Liberals who opposed home rule and were called the Unionists. They were suppported by Ulster MPs. Ulster protestants feared that home rule would allow discrimination at the hands of the Catholic majority. They adopted the phrase "Home rule means Rome rule". The issue was largely dropped from the political agenda by 1894. There was some revival of irish nationalism and Sinn Fein emerged in 1905 under Arthur Griffith however neither attracted much support

The Liberals won a landslide victory…
