What impact did the Irish War of Independence have on the partition of Ireland?

The Irish War of Independence had a significant impact on the partition of Ireland. It led to the signing of the Anglo-Irish Treaty in 1921, which resulted in the creation of the Irish Free State in 1922. This partitioned Ireland into two separate entities: Northern Ireland, which remained part of the United Kingdom, and the Irish Free State, which became a self-governing dominion within the British Empire. The war and subsequent partition deepened the divide between the predominantly Catholic nationalist population in the south and the predominantly Protestant unionist population in the north, setting the stage for ongoing tensions and conflicts in Northern Ireland.
