Urraca of León and Castile

Urraca (c. 1081–1126), called the Reckless, was the daughter of Alfonso VI of León. Her half-brother Sancho's death in battle in 1108 left her the heir, and in 1109 she inherited León, Castile and Galicia, western Europe's first queen regnant.

Widowed by Raymond of Burgundy, she married Alfonso I of Aragon late in 1109. His abuse drove her away by 1110, and the marriage was annulled in 1112. War with Aragon and rebel Galicia followed. She died at Saldaña in 1126, and her son Alfonso VII succeeded her.
