Irish Republicanism is a political ideology that advocates for the establishment of an independent and united Ireland. It seeks to end British rule in Northern Ireland and promote the idea of a sovereign Irish state. This movement has historical roots in the struggle against British colonialism and has evolved over the years, encompassing various political and social perspectives. The ideology has been associated with several groups and events, including the Easter Rising of 1916 and the Irish Republican Army (IRA). While some factions have pursued their goals through peaceful means, others have resorted to armed conflict, leading to significant political and social divisions within Ireland and beyond.
