Fruela II of Asturias and León

Fruela II (c. 874–925), youngest son of Alfonso III of Asturias, received Asturias when his brothers deposed their father and divided the kingdom in 910. His diminished kingdom remained subordinate to León.

He consolidated the region later called Castile, while acknowledging the hegemony of his brother Ordoño II of León. When Ordoño died in 924 the magnates ignored his young sons and elected Fruela king of León.

He alienated the nobles by putting two noble brothers to death, and after only fourteen months died of leprosy in August 925. His death opened a succession war between his sons and Ordoño's.
