I want to know the answer to the following question:
When did the Anglo-Irish War end?
All the background I'm provided with is that "The Anglo-Irish War ended in 1921 with a stalemate and the signing of the Anglo-Irish Treaty, creating the Irish Free State, a Dominion within the British Empire, with effective internal independence but still constitutionally linked with the British Crown.". Is that enough to answer the question?
Answer: yes
