The battle was commanded by three Christian kings; Alfonso VIII of Castile, Peter II of Aragon and Sancho VII of Navarre.

He was succeeded by his sister Berengaria, with the support of Lope Díaz, amongst other nobles, who later abdicated in favor of her son Ferdinand III of Castile, crowned in Nájera.

During this invasion, Álvaro Núñez de Lara gained power in Nájera and was subsequently defeated and imprisoned by Lope Díaz.

In the early 1230s, the bishop of Calahorra wanted to exert his power over all the churches subject to the Monasteries of San Millán de la Cogolla.

By 1235, the fallout from this shakeup was so great that Lope was forced to expel the bishop who fled to Rome and the diocese moved back to Calahorra.
