The Sephardic Diaspora After 1492

Or, the story of how the so-called marranos returned to Judaism.


By the 16th century, Jewish life in Spain and Portugal–the Jewish “Sepharad” that had boasted of a vibrant cultural life in the Middle Ages–was officially non-existent. Spanish Jewry had been exiled in 1492, and all of the Jews of Portugal, many of whom were refugees from Spain, were forcibly converted only five years later, in 1497. Many of these converts, known as conversos, assimilated fully into Iberian society. But a significant segment maintained a façade of Christianity while still clandestinely retaining as much of their Jewish belief and practice as possible.

Over the next few centuries, many of these crypto-Jews settled in Western Europe. The migration of the Sephardic Diaspora from Spain and Portugal heralded a dual process of return: return to lands uninhabited by Jews for centuries, and return to ancestral practices that did not have the benefit of a chain of tradition to faithfully transmit them.

A People Apart, A New Exodus

Though the Jews of Portugal had been forced to convert, there was no official enforcement of that conversion, so they were generally free to practice their Judaism secretly. During the early 16th century, crypto-Jews (disparagingly labeled marranos, literally swine, by Christians of pure lineage) entered many levels of Portuguese society and forged a group identity that, on account of its conversion as a complete group, maintained resilience and vitality.

But the introduction of the Inquisition into Portugal in 1536 spurred waves of crypto-Jewish emigration. The pressure to flee persecution was compounded with a search for greater economic opportunity. 

Ironically, many conversos first moved to Spain, as it offered greater wealth and, according to Inquisitorial practice, could not punish crimes against the faith committed in Portugal. Portuguese Jewish migration was so extensive that, for many Spaniards, “Portuguese” became a synonym for “Jew.”
