What happened
Concerned that Strongbow was building an independent power base in Ireland, King Henry II of England sailed from Pembroke and landed on the Waterford coast on 17 October 1171, the first reigning king of England to set foot on Irish soil. He brought an army estimated at 4,000 men, including 500 knights, and Strongbow submitted immediately, surrendering the kingdom of Leinster and the towns of Dublin, Waterford, and Wexford to the crown. Henry arrived in Dublin on 11 November and held a Christmas feast at which numerous Irish kings and lords submitted to him. He regranted Leinster to Strongbow as a subordinate lordship while keeping Dublin and Waterford as royal towns directly under the crown, and he granted Dublin its first charter, a small piece of parchment that still survives. The 1175 Treaty of Windsor formalized Henry as overlord of the conquered territory while the Irish high king Ruaidri retained the rest of the island, though also swearing fealty to Henry.
Why it matters
Henry's 1171 visit converted a private Norman land-grab into a royal lordship of Ireland, establishing the legal claim that English monarchs would cite for the next several centuries, and it set the pattern of absentee rule from England that defined Ireland's constitutional position until independence in the 20th century.
How we know
Henry's 1171 landing, his reception of Strongbow's submission, and the 1175 Treaty of Windsor are documented in Anglo-Norman chronicles of the period and in the surviving Dublin city charter Henry issued, still preserved today.
