Racial Antisemitism - Pre-19th Century

Pre-19th Century

Racial antisemitism has existed alongside religious antisemitism since the Middle Ages, if not earlier. In Spain even before the Edict of Expulsion of 1492, Spanish Jews who converted to Catholicism (conversos in Spanish), and their descendants, were called New Christians. They were frequently accused of lapsing to their former religious practices ("Crypto-Jews"). To isolate conversos, the Spanish nobility developed an ideology of "cleanliness of blood". The conversos were called "New Christians" to indicate their inferior status in society. That ideology was a form of racism, as in the past there were no grades of Christianity and a convert had equal standing. Cleanliness of blood was an issue of ancestry, not of personal religion. The first statute of purity of blood appeared in Toledo in 1449, where an anti-converso riot lead to conversos being banned from most official positions. Initially these statutes were condemned by the monarchy and the Church. However, the New Christians came to be hounded and persecuted by the Spanish Inquisition after 1478 and the Portuguese Inquisition after 1536.

It has been said that much of the discrimination against the New Christians in Spain and Portugal was because they were the only educated class outside of the nobility at the time. Laws against them were meant to preserve aristocratic monopoly over lucrative Crown positions and contracts. Large portions, maybe majorities, of the embryonic middle classes such as merchants and professionals, were composed of "New Christians", which supported the power of the king against the high nobility. It is claimed that the antagonism between the educated and merchant "New Christians" and the aristocratic and landed "Old Christians" was a class struggle.

In Portugal, the legal distinction between "New" and "Old" Christians continued until the issue of a legal decree by the Marquis of Pombal in 1772.
