the emirate of granada, whose forces would later be bolstered by volunteers from north africa, fully supported the rebellion. additional muslim troops from north africa attempted a landing in the guadalquivir estuary but were repulsed by alfonso. ultimately, north african troops did not play a significant role in the war. muslims from old and new castile, such as those from ávila, burgos, arévalo and madrid, which had been under castilian rule for generations and did not suffer from alfonso's relocation policy, largely did not join the rebellion.
