Bermudo III
king of Leon
Quick Summary
Bermudo III was the king of León from 1028 to 1037. He succeeded his father, Alfonso V, who was killed during the siege of Viseu. Bermudo III's reign was marked by conflict with his brother-in-law, Sancho III of Pamplona, who sought to expand his influence over León. This rivalry ultimately led to Bermudo III's death in battle in 1037, after which Sancho III's son, Ferdinand I, became king of León, uniting it with Castile.12
