What was the treaty between Ireland and England about?

The treaty between Ireland and England, known as the Anglo-Irish Treaty, was signed in December 1921 and established the Irish Free State as a self-governing dominion within the British Commonwealth. It aimed to resolve conflict over Irish independence and set the framework for Irish governance while maintaining certain ties to Britain. The treaty also included provisions for the partition of Ireland, leading to the creation of Northern Ireland. Its acceptance led to significant political divisions in Ireland and ultimately sparked the Irish Civil War.
