Anglo-Irish War

The Anglo-Irish War (1919–1921) was a conflict between Irish republicans seeking independence and British forces controlling Ireland. Irish fighters, mainly the Irish Republican Army (IRA), engaged in guerrilla tactics against British soldiers and agents to end British rule. The war stemmed from long-standing desire for self-governance and the push for Irish independence. It resulted in the Anglo-Irish Treaty, which established the Irish Free State as a self-governing dominion, though Northern Ireland remained part of the UK. The conflict was a pivotal step toward Ireland's full independence, though it also caused divisions and lasting impacts within Irish history.
