The word Fenian (/ˈfiːniən/) served as an umbrella term for the Irish Republican Brotherhood (IRB) and their affiliate in the United States, the Fenian Brotherhood. They were secret political organisations in the late 19th and early 20th centuries dedicated to the establishment of an independent Irish Republic. In 1867, they sought to coordinate raids into Canada from the United States with a rising in Ireland.[1][2] In the 1916 Easter Rising and the 1919–1921 Irish War of Independence, the IRB led the republican struggle.
