Ireland

As early as 1913 Lloyd George expressed interest in the issues surrounding the of Irish Home Rule movement. He stated that he supported "...the principle of a referendum...each of the Ulster Counties is to have the option of exclusion from the Home Rule Bill". Had a referendum occurred it is quite possible that only four of Ulster's nine Counties would have voted for exclusion (see List of MPs elected in the 1918 United Kingdom general election). During Asquith's premiership, the armed insurrection by Irish republicans, known as the Easter Rising, had taken place in Dublin during Easter Week, 1916. The government responded with harsh repression; key leaders were quickly executed. The mostly Catholic Irish nationalists then underwent a dramatic change of mood, and shifted to demand vengeance and independence.

In 1917 Lloyd George called the 1917–18 Irish Convention in an attempt to settle the outstanding Home Rule for Ireland issue; however, the upsurge in republican sympathies in Ireland following the Easter Rising coupled with Lloyd George's disastrous attempt to extend conscription to Ireland in April 1918 and led to the landslide victory of Sinn Féin and the wipeout of the Irish Parliamentary Party at the December 1918 election. Replaced by Sinn Féin MPs, they immediately declared an Irish Republic.

Lloyd George presided over the Government of Ireland Act 1920 which partitioned Ireland into Southern Ireland and Northern Ireland in May 1921 during the Anglo-Irish War. Lloyd George famously declared of the Irish Republican Army that "We have murder by the throat!" However, he soon afterwards began negotiations with IRA leaders to recognise their authority and to end a bloody conflict. Lloyd George also invited the leader of northern Irish Unionists James Craig to the negotiations but he refused to attend. Lloyd George wrote to Craig on 14 November 1921 "Your proposal to leave the six counties under the Northern Parliament would stereotype a frontier based neither upon natural features nor broad geographical considerations by giving it the character of an international boundary. Partition upon these lines the majority of the Irish people will never accept, nor could we conscientiously attempt to enforce it." (See The Troubles in Northern Ireland (1920–1922)). The Anglo-Irish Treaty was signed in December 1921 with Irish leaders. The Parliament of Northern Ireland exercised Article 12 of the Treaty to opt out of the Irish Free State. The Treaty established the Irish Boundary Commission to draw a border between Northern Ireland and the rest of Ireland "in accordance with the wishes of the inhabitants, so far as may be compatible with economic and geographic conditions...". Southern Ireland, representing over a fifth of the United Kingdom's territory, seceded in 1922 to form the Irish Free State. (See Partition of Ireland).
