The Irish delegation at the Anglo-Irish Treaty talks in London are given an ultimatum by British Prime Minister David Lloyd George on December 5, 1921. Sign the treaty or face “immediate and terrible war.”

In 1920, during the Irish War of Independence, the Government of Ireland Act not only establishes the new state of Northern Ireland but gives that state the right to opt-out of a future self-governing Irish Free State within the British Commonwealth of Nations.

The Northern state consists of the six northeastern counties of Ulster with a unionist majority. They are Antrim, Down, Armagh, Derry, Tyrone, and Fermanagh. Belfast is to be the seat of a government and hold limited devolved powers. The counties of Donegal, Cavan, and Monaghan are to be absorbed within the Irish Free State controlled from parliament in Dublin.

Irish nationalists are dismayed with the plan. Protestant Unionists, particularly those living within the boundaries of the new state, accept and start to implement the Act. Sectarian attacks are launched upon Catholic homes in Belfast, Derry, Banbridge, Lisburn, and Dromore. Catholics are driven from Belfast shipyards and from various engineering works in the city. Supposedly these attacks are in revenge for Irish Republican Army (IRA) assassinations.

The IRA continues the campaign to establish a republic with the Irish War of Independence. By the middle of 1921, both sides are exhausted, and a truce is called on June 9.

In July 1921, Éamon DeValera, the president of Dáil Éireann, goes to London to meet with Prime Minister Lloyd George. They agree an Irish delegation will come to London to discuss terms in the autumn.

The delegation appointed by the Dáil to travel to London consists of Arthur Griffith (Minister for Foreign Affairs and chairman of the delegation); Michael Collins (Minister for Finance and deputy chairman of the delegation); Robert Barton (Minister for Economic Affairs); George Gavan Duffy and Éamonn Duggan, with Erskine Childers, Fionán Lynch, Diarmuid O’Hegarty, and John Chartres providing secretarial assistance. DeValera himself does not attend. Future historians wonder if he knew they would not be able to negotiate a 32 county Irish Republic.

During the debate, Lloyd George insists Ireland remain part of the Commonwealth and Dáil Éireann members take the oath of allegiance to the British throne. After a delay of two months, Lloyd George delivers the ultimatum on December 5, sign a treaty within three days or there will be war.

The Anglo-Irish Treaty is to give Ireland a 26 county Free State with Dominion status. The right to raise taxes, regulate foreign trade, independence in internal affairs, own an army, and the oath of allegiance is changed to one of fidelity.

The British are to retain three naval bases within the jurisdiction of the Free State, at Cobh, Lough Swilly, and Berehaven. The Northern Ireland boundary is to be determined by a commission. This gives false hope to large tracts of Tyrone, Fermanagh, Down, Armagh, and Derry City would be given to the Free State as they have Catholic majorities.

Just after 2:00 AM on December 6, 1921, the Irish delegation, without consulting the Dáil, finally sign a treaty with the British. Collins writes, prophetically, later on the day of the signing, “early this morning I signed my death warrant.”

The Treaty displeases the Catholics in the north and the unionists in the south. Meanwhile, many of those involved in the conflict are abhorred at the fact that not all of Ireland is to leave the United Kingdom.
