The crisis deepened during the 17th century with the expulsion in 1609 of the Moriscos, descendants of the Muslim population that had converted to Christianity. The Spanish government systematically forced Moriscos to leave the kingdom for Muslim North Africa. They were concentrated in the former Crown of Aragon, and in the Kingdom of Valencia specifically, they constituted roughly a third of the total population. The expulsion caused the financial ruin of some of the Valencian nobility and the bankruptcy of the Taula de canvi financial institution in 1613.
