Information about Ruaidhrí Ó Conchobhair, High King of Ireland

Ruaidrí Ua Conchobair (Modern Irish: Ruaidhrí Ó Conchobhair, or, Ruairí Ó Conchúir; commonly anglicised as Rory O'Conor) was King of Connacht from 1156 to 1186, and High King of Ireland from 1166 to 1193. He was the last High King of Ireland before the Norman invasion (Brian Ua Néill and Edward Bruce both claimed the title with opposition in later years).

Ruaidrí was one of over twenty sons of King Tairrdelbach Ua Conchobair (1088–1156). He and his sister Mór were Tairrdelbach's only children from his third wife, Cailech Dé Ní hEidin of Aidhne.
