Fenian movement

Fenian movement, movement for Irish independence from Great Britain in the mid- to late 1800s. Named after warriors from Irish mythology, the Fenians organized both in the United States and England. Also known as the Irish Republican Brotherhood, they directed raids in Ireland, England, and Canada. Later Irish republican movements advanced the goal of independence for Ireland and, after years of skirmishes and guerilla warfare, independence was won for southern Ireland (1921), northern Ireland remaining under British control.
