attacks came later in the century from mobs of angry Catholics, led by popular preachers, who would storm into the Jewish quarter, destroy synagogues, and break into houses, forcing the inhabitants to choose between conversion and death. Thousands of Jews sought to escape these attacks by converting to Christianity. These Jewish converts were commonly called conversos, New Christians, or marranos; the latter two terms were used as insults. At first, these conversions seemed an effective solution to the cultural conflict: many converso families met with social and commercial success. But eventually their success made these new Catholics unpopular with their neighbors, including some of the clergy of the Church and Spanish aristocrats competing with them for influence over the royal families. By the mid-fifteenth century, the demands of the Old Christians that the Catholic Church and the monarchy differentiate them from the conversos led to the first limpieza de sangre laws, which restricted opportunities for converts. These suspicions on the part of Christians were only heightened by the fact that some of the coerced conversions were undoubtedly insincere. Some, but not all, conversos had understandably chosen to salvage their social and commercial positions or their lives by the only option open to them – baptism and embrace of Christianity – while privately adhering to their Jewish practice and faith. Recently converted families who continued to intermarry were especially viewed with suspicion. These secret practitioners are commonly referred to as crypto-Jews or marranos. The existence of crypto-Jews was a provocation for secular and ecclesiastical leaders who were already hostile toward Spain's Jewry. For their part, the Jewish community viewed conversos with compassion, because Jewish law held that conversion under threat of violence was not necessarily legitimate. Although the Catholic Church was also officially opposed to forced conversion, under ecclesiastical law all baptisms were lawful, and once baptized, converts were not allowed to rejoin their former religion. The uncertainty over the sincerity of Jewish converts added fuel to the fire of antisemitism in fifteenth-century Spain. European context From the thirteenth to the sixteenth centuries, European countries expelled the Jews from their territories on at least fifteen occasions. Before the Spanish expulsion, the Jews had been expelled from England in 1290, several times from France between 1182 and 1354, and from some German states. The French case is typical of most expulsions: whether the expulsion was local or national, the Jews usually were
