Treaty ofWindsor (1175)

Abstract

The Treaty of Windsor was concluded on October 6, 1175, between King Henry II of England and Rory O'Connor, king of Connacht and high king of Ireland. The treaty formalized the land‐holdings of Henry and his Anglo‐Norman lords in Ireland as well as those of the native Irish, and further established that Rory was to be king under Henry II with other Irish lords serving under him and paying tribute to the English king through him. The treaty may not have lasted more than a few years but is often seen as a watershed in the history of Ireland and indirectly leading to more than 700 years of direct English and, later, British involvement in Ireland.
