Irish republicans led by Patrick Pearse began the Easter Rising against British rule in Ireland, and proclaimed the Irish Republic an independent state.

Irish republicanism is the political movement for an Irish republic, void of any British rule. Throughout its centuries of existence, it has encompassed various tactics and identities, simultaneously elective and militant and has been both widely supported and iconoclastic.

Patrick Henry Pearse was an Irish teacher, barrister, poet, writer, nationalist, republican political activist and revolutionary who was one of the leaders of the Easter Rising in 1916. Following his execution along with fifteen others, Pearse came to be seen by many as the embodiment of the rebellion.

The Easter Rising, also known as the Easter Rebellion, was an armed insurrection in Ireland during Easter Week in April 1916. The Rising was launched by Irish republicans against British rule in Ireland with the aim of establishing an independent Irish Republic while the United Kingdom was fighting the First World War. It was the most significant uprising in Ireland since the rebellion of 1798 and the first armed conflict of the Irish revolutionary period. Sixteen of the Rising's leaders were executed starting in May 1916. The nature of the executions, and subsequent political developments, ultimately contributed to an increase in popular support for Irish independence.

The Proclamation of the Republic, also known as the 1916 Proclamation or the Easter Proclamation, was a document issued by the Irish Volunteers and the Irish Citizen Army during the Easter Rising in Ireland, which began on 24 April 1916. In it, the Military Council of the Irish Republican Brotherhood, writing in English as the "Provisional Government of the Irish Republic," proclaimed Ireland's independence from the United Kingdom. The reading of the proclamation by Patrick Pearse outside the General Post Office (GPO) on Sackville Street, Dublin's main thoroughfare, marked the beginning of the Rising. The proclamation was modelled on a similar independence proclamation issued during the 1803 rebellion by Robert Emmet.
