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 "In 1919, the frustrations caused by delays to Irish home rule led members of Sinn Féin, a pro-independence party that had won a majority of the Irish seats at Westminster in the 1918 British general election, to establish an Irish assembly in Dublin, at which Irish independence was declared.". Is that enough to answer the question?
Answer: no
