The Battle of Candespina was fought on 26 October 1110[1] or 1111 between the forces of Alfonso I of Aragon and those of his estranged wife, Urraca of León and Castile, in the Campo de la Espina near Sepúlveda.

Perhaps the latter had become too powerful, for one of her strongest vassals, her brother-in-law Henry of Portugal, who had been recruiting soldiers in France (probably his native Burgundy), returned to ally with Alfonso after being promised a partition of the united realm that would leave him in control of the west (Galicia and Portugal).

[4] After the battle Urraca was joined in Burgos by the Castilian count Pedro González de Lara.

After the battle he was approached by some men of Urraca at Sepúlveda, where they offered him a better partition if he joined the queen.

In support of this, Luiz Gonzaga de Azevedo chronicled the career of Henry of Portugal, placing his trip to France in the early spring of 1110.
