After the Dáil voted by 64 to 57 to approve the Treaty in January, 1922, De Valera resigned the presidency ( which in August 1921 had been upgraded from a prime ministerial President of Dáil Éireann to a full head of state, called President of the Irish Republic ).

He told the Dáil on 27 September 1922, " although I have always objected to the death penalty, there is no other way that I know of in which ordered conditions can be restored in this country, or any security obtained for our troops, or to give our troops any confidence in us as a government ".

* Constituencies of the House of Commons of the United Kingdom ( 1801 – 1922 ) and First Dáil 1918

Following the formation of the independent Irish Free State in 1922, members of the lower house of the Oireachtas ( parliament ), Dáil Éireann ( or " the Dáil ") are termed Teachtaí Dála ( Teachta Dála singular ) or TDs.

Following the signing of the 1922 Anglo-Irish Treaty, which brought the Irish War of Independence to an end, the single chamber Dáil became the lower house of a new bicameral Oireachtas, the parliament of the newly established Irish Free State.

Article 28 of the Constitution of the Irish Free State ( 1922 ) set the maximum term for the Dáil at four years.

When the Fourth Ministry assumed office in 1922, with Arthur Griffith as its head, cabinet members were once again described as ministers and Griffith, a monarchist, adopted the practice of referring to himself as the President of Dáil Éireann, although President of the Republic remained his official title.

The four Presidents of the Ministry of Dáil Éireann, during the years 1919 to 1922.

In August 1922 in the run-up to the negotiations that would produce the Anglo-Irish Treaty, de Valera asked the Dáil to amend the constitution to upgrade his official status to that of head of state, in part to give him equality with King George V of the United Kingdom in accrediting delegates to the negotiations.

He then remained in office until January 1922 when, against his wishes, the Dáil voted to ratify the Anglo-Irish Treaty.

However after de Valera left office in 1922 leaders resumed the practice of using the lesser title President of Dáil Éireann.

In 1922 after the ratification of the Anglo-Irish Treaty, the institutions mentioned in the Dáil Constitution began to operate in parallel with a rival set of structures.

When the " house of parliament " was convened in 1922 it was treated by those in attendance as the Third Dáil, and its first act was to merge the Provisional Government and the Ministry of the Dáil into a single cabinet.

The Dáil Constitution finally became defunct when the new Constitution of the Irish Free State came into force on 6 December 1922.

*: Following Arthur Griffith's death and Michael Collins's assassination in August 1922, Cosgrave simultaneously held both their offices ; like Griffith he used the title " President of Dáil Éireann ".

In reality all distinction between both offices and indeed both states ceased to exist – by September 1922 it was not even clear when TDs assembled whether they were meeting as the Dáil or the Provisional Parliament of the treaty state.

The office was continued under the 1922 – 1937 Irish Free State, the constitution of which referred to the office-holder as the " Chairman of Dáil Éireann ".

Elections in June 1922 were followed by the meeting of the Third Dáil, which worked as a Constituent Assembly to draft a constitution for the Irish Free State.

The Irish Free State created by the Treaty came into force on 6 December 1922 by royal proclamation after its constitution had been enacted by the Constituent Assembly ( the Third Dáil ) and the British parliament.

However as it was still under the control of the British Army, who had yet to withdraw from it, and the new Governor-General of the Irish Free State was due to deliver the Speech from the Throne opening parliament within weeks, it was decided to hire the main RDS Lecture Theatre attached to Leinster House for use in December 1922 as a temporary Dáil chamber.
