The agreement was signed in London on 6 December 1921, by representatives of the British government (which included Prime Minister David Lloyd George, who was head of the British delegates, and Winston Churchill, who was Secretary of State for the Colonies) and by representatives of the government of the Irish Republic (which included Michael Collins, who was Secretary of State for Finance, and Arthur Griffith, who was Secretary of State for Foreign Affairs). The Irish representatives had plenipotentiary status (negotiators empowered to sign a treaty without reference back to their superiors) acting on behalf of the Irish Republic, though the British government declined to recognise that status. As required by its terms, the agreement was approved by "a meeting" of the members elected to sit in the House of Commons of Southern Ireland and [separately] by the British Parliament. In reality, Dáil Éireann (the legislative assembly for the de facto Irish Republic) first debated then approved the treaty; members then went ahead with the "meeting". Though the treaty was narrowly approved, the split led to the Irish Civil War, which was won by the pro-treaty side.

The Irish Free State as contemplated by the treaty came into existence when its constitution became law on 6 December 1922 by a royal proclamation.

Content

Among the treaty's main clauses were that:

  • Crown forces would withdraw from most of Ireland.
  • Ireland was to become a self-governing dominion of the British Empire, a status shared by Australia, Canada, Newfoundland, New Zealand, and the Union of South Africa.
  • As with the other dominions, the King would be the Head of State of the Irish Free State (Saorstát Éireann) and would be represented by a Governor General (see Representative of the Crown).
  • Members of the new free state's parliament would be required to take an Oath of Allegiance to the Irish Free State. A secondary part of the oath was to "be faithful to His Majesty King George V, His heirs and successors by law, in virtue of the common citizenship".
  • Northern Ireland (which had been created earlier by the Government of Ireland Act) would have the option of withdrawing from the Irish Free State within one month of the Treaty coming into effect.
  • If Northern Ireland chose to withdraw, a Boundary Commission would be constituted to draw the boundary between the Irish Free State and Northern Ireland. The Northern government did not name a representative to the Commission as it did not consider itself bound by a Treaty which it had never assented to.
  • Britain, for its own security, would continue to control a limited number of ports, known as the Treaty Ports, for the Royal Navy.
  • The Irish Free State would assume responsibility for a proportionate part of the United Kingdom's debt, as it stood on the date of signature.
  • The treaty would have superior status in Irish law, i.e., in the event of a conflict between it and the new 1922 Constitution of the Irish Free State, the treaty would take precedence.
