Timeline

  1. 1104–1114Zaragoza · AragonAlfonso I succeeded his brother Pedro I as King of Aragon and Pamplona in 1104 and immediately launched offensives against Muslim territory. In 1109 he married Urraca, queen of León, seeking to unite Christian Iberian forces through marriage, but the union soon broke down and sparked long power conflicts.
  2. 1118–1125León · Castile and LeónAlfonso I and Urraca were long opposed over the succession to the León-Castile throne, contesting guardianship of his stepson Alfonso VII. Fighting was frequent in the early 1120s; in 1125 the two sides signed the Treaty of Támara making peace, and Alfonso VII was recognized as ruler of León.
  3. 1125–1134Central Iberia · Iberian PeninsulaAfter the 1125 peace, Alfonso I threw himself into offensives against Almoravid al-Andalus. In 1129 he decisively defeated the Muslim army at the Battle of Cutanda, recovering vast territories. In 1131 he marched into Navarre to consolidate royal authority, and in 1134 died while besieging Fraga held by the Muslims, his lack of heirs causing a succession crisis in Aragon.
