Under the Dáil Constitution adopted in 1919, Dáil Éireann continued to exist. De Valera resigned the presidency and sought re-election (in an effort to destroy the newly approved Treaty), but Arthur Griffith defeated him in the vote and assumed the presidency. (Griffith called himself President of Dáil Éireann rather than de Valera's more exalted President of the Republic.) However this government or Áireacht had no legal status in British constitutional law, so another co-existent government emerged, answerable to the House of Commons of Southern Ireland. The new Provisional Government formed under Michael Collins, who became President of the Provisional Government (i.e., prime minister). He also remained Minister for Finance of Griffith's republican administration. An example of the complexities involved can be seen even in the manner of his installation. In theory he was a Crown-appointed prime minister, installed under the Royal Prerogative. To be so installed, he had to formally meet the Lord Lieutenant of Ireland, Viscount Fitzalan (the head of the British administration in Ireland). According to republican history, Collins met Fitzalan to accept the surrender of Dublin Castle, the seat of British government in Ireland. According to British constitutional theory, he met Fitzalan to 'kiss hands' (the formal name for the installation of a minister of the Crown), the fact of their meeting rather than the signing of any documents, duly installing him in office.
Anti-treatyites, having opposed the Treaty in the Dáil, withdrew from the assembly and, having formed an opposition 'republican government' under Eamon de Valera, began a campaign that led to the Irish Civil War. By mid-1922, Collins in effect laid down his responsibilities as President of the Provisional Government to become Commander-in-Chief of the National Army, a formal structured uniformed army that formed from the remnants of the Old IRA. As part of those duties, he travelled to his native Cork. En route home through County Cork on 22 August 1922, at Beal na mBlath (an Irish language term that means 'the Mouth of Flowers'), he was killed in an ambush, probably by a ricocheting bullet. He was not yet 32 years old.
