Cathal Brugha, Irish revolutionary and politician, active in the Easter Rising, Irish War of Independence; first Ceann Comhairle and first President of Dáil Éireann (born 1874)

Cathal Brugha was an Irish republican politician who served as Minister for Defence from 1919 to 1922, Ceann Comhairle of Dáil Éireann in January 1919, the first president of Dáil Éireann from January 1919 to April 1919 and Chief of Staff of the Irish Republican Army from 1917 to 1918. He served as a Teachta Dála (TD) from 1918 to 1922.

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 Irish War of Independence, also known as the Anglo-Irish War, was a guerrilla war fought in Ireland from 1919 to 1921 between the Irish Republican Army and British forces: the British Army, along with the quasi-military Royal Irish Constabulary (RIC) and its paramilitary forces the Auxiliaries and Ulster Special Constabulary (USC). It was part of the Irish revolutionary period.
