The Irish Parlimentary Party (IPP) had aimed to get independence from England for years, but a majority of people were more attracted to Sinn Féin (means "We Ourselves"). When Sinn Féin won in 1918, they decided to not represent Ireland in the British Parliament but to start an Irish Parliament in Dublin. On January 21, 1919, the Sinn Féin gathered to start Dáil Éireann (a new Irish parliament) and proclaimed Irish independence. After attacks on the Irish Constabulary--which was supported by the British government--by the Irish Republican Army (IRA) and how the Dáil supported the IRA, this was seen as Ireland declaring war. Thus, this began the Anglo-Irish War where the IRA used guerilla warfare to attack the British security forces. (It is important to note that both sides committed attrocities.) The war came to an end in 1921 with Irish and British forces signing a treaty for an Irish "free state." The UK monarch at the time did still have some power in the Free State and Ireland split into two parts, with Northern Ireland being against the Free State.
