On May 25, 1566 Philip II decreed the use of the Arabic language (written or spoken) illegal, doors to homes to remain open on Fridays to verify that no Muslim Friday prayers were conducted, and heavy taxation on Moriscos trades. This led to several rebellions, one of them in Ronda under the leadership of Al-Fihrey. After a ferocious battle, Al-Fihrey's insurgent army was able to defeat the Spanish army sent to suppress them under the leadership of Alfonso de Aguilar. So violent was the retribution that no Spanish soldier captured was spared his life, including Alfonso himself. This prompted Phillip II to order the massacre of all Moriscos in Ronda. Those few who survived were sold into slavery.
