Michael Collins left a significant legacy in Irish history as a leader in the struggle for Irish independence. As a key figure in the Irish Republican Army (IRA), he played a pivotal role in the 1916 Easter Rising and subsequent guerrilla warfare against British forces. Collins was instrumental in negotiating the Anglo-Irish Treaty, which established the Irish Free State but also sparked a civil war. His vision of a united Ireland and his efforts in building a new government shaped the nation’s path. Despite his assassination in 1922, Collins remains a symbol of courage and nationalism in Ireland's history.
