The proclamation of Irish Independence by Irish Republicans during the Easter Rising of 1916. The uprising was brutally crushed and several leaders were executed by British forces; however, the defeat served as a rallying cry for Irish independence, resulting in a protracted insurgency and eventual Irish independence in 1922.

Sinn Féin - Arthur Griffith helped found the Sinn Féin movement in 1905, following the emergence of a more militant nationalist spirit in Ireland. Its name ‘Ourselves’ indicated an emphasis on economic and cultural self-sufficiency, as well as political independence. It was widely held responsible in both Britain & Ireland for the Easter Rising, though as an organisation it had not participated. In the December 1918 general election, Sinn Féin won 73 of the 103 Irish seats.
