To the best of my knowledge they were subject to the same rules as the Jews of Spain = convert, leave or die. It is obvious that the staunchly Catholic Isabella and Ferdinand of Castile and Aragon would NOT permit the continued presence in their christian kingdom (catholic = universal) and that non-catholics would leave with as little as possible. Some Jews remained and chose to convert, the conversos or as Spaniards would call them, Marranos (pigs). They were never trusted as it was believed, with some justification, that they continued to practice their religion secretly and in private. They constituted a significant portion of the over three thousand people executed for heresy by the Spanish Inquisition.

I imagine things were no easier for muslims, presuming they were given the same opportunities.The Spanish policy towards the Muslims was not much different. In 1492, there were about 500,000 Muslims throughout Spain. The Catholic Church made it a priority to convert them all to Christianity now that they did not have the protection of a Muslim state.

The first attempts to convert Muslims to Christianity was through bribery. Converts were showered with gifts, money, and land. This approach proved to be unsuccessful, as most of these “converts” quickly returned to Islam after getting such gifts.

When it became clear in the closing years of the 1400s, that the Muslims of Spain were more attached to their beliefs than to wealth, Spain’s rulers took a new approach. In 1499, Francisco Jimenez de Cisernos, a cardinal in the Catholic Church was sent to southern Spain to “speed up” the conversion process. His approach was to harass the Muslims until they converted. All manuscripts written in Arabic were burned (except for medical ones). Muslims who refused to convert were arbitrarily sent to prison. They were tortured and had their property confiscated in an attempt to convince them to convert. This was all part of Cisernos’ policy that “if the infidels [Muslims] couldn’t be attracted to the road of salvation, they had to be dragged to it.”

Granada’s Muslims especially openly protested in the streets and threatened to overthrow the oppressive Catholic rule and replace it with a new Muslim state. Spain’s king and queen quickly intervened along with Cisernos. They gave Granada’s rebels a choice – conversion or death. Almost all of Granada’s citizens chose to convert on the outside, but secretly kept Islam as their true religion.

In 1502, King Ferdinand and Queen Isabella officially made Islam illegal throughout Spain. In the countryside, the Muslim towns throughout Granada rose in revolt. They took refuge in the rocky Alpujarras Mountains in Southern Spain, making it difficult for the Christian authorities to root them out. The rebels had no clear plan nor one central leader. They were united in their belief in Islam and resistance to Christian rule. Since almost all of the population of Granada was Muslim, the rebellion took a defensive form. Christian soldiers regularly attacked Muslim towns in an attempt to force its residents into conversion. The Muslim rebels, not as well equipped or trained as the Christian soldiers, were not always able to rebel the attacks. Massacres and forced conversions of villages were common.

By 1502, the rebellion had petered out and Queen Isabella officially declared an end to toleration for any and all Muslims in Spain. Thus, all Muslims had to officially convert to Christianity, leave Spain, or die. Many did, in fact, flee to North Africa or fight to the death, however, most officially converted to Christianity, while still keeping their true beliefs hidden. So Spain’s Muslim population went underground in 1502 and had to hide their faith and actions from the Spanish authorities to avoid being killed. These “converted” Muslims were known as Moriscos by the Spanish, and they were intently watched.

Spanish government officials placed strict restrictions on the Moriscos to try to make sure they were not still secretly practicing Islam, which many were of course doing. Moriscos had to leave the doors to their homes open on Thursday nights and Friday mornings, so soldiers can pass by and look in to make sure they were not bathing, as Muslims are supposed to do before the congregational prayer of Friday. Any Muslim caught reading the Quran, or making wudu (ablution) could be immediately killed. For this reason, they were forced to find ways to practice their religion in secret, constantly in fear of being found. (Jewish Marranos had secret rooms hidden in basement areas.)

Even under such difficult circumstances, the Moriscos retained their beliefs for decades. While the community activities of Islam such as congregational prayer, alms giving, and pilgrimage to Makkah were restricted, they were able to continue to practice in secret.

Despite the best efforts of the Moriscos to conceal their practice of Islam, the Christian kings suspected them of continued adherence to Islam. In 1609, over 100 years after the Muslims went into hiding, King Phillip of Spain signed an edict expelling all Moriscos from Spain. They were given only 3 days to completely pack up and board ships destined for North Africa or the Ottoman Empire.

During this time, they were constantly harassed by Christians, who would loot their belongings and kidnap Muslim children to raise as Christians. Some Moriscos were even killed for sport on their way to the coast by soldiers and regular people. Even when they got to the ships that would take them to their new lands, they were harassed. They were insultingly expected to pay their own fare in their exile. Also, many of the sailors raped, killed, and stole from the Moriscos they were carrying on their ships. The Spanish government made very clear their desire to harass and make life miserable for Spain’s Muslims as they were on their way out.

The commonality, therefore, of Jewish and Islamic experience is striking.
