The Inquisition was created in the twelfth century to find "Christian heretics" who would be punished or killed. Eventually, Jews too were open to such charges of heresy, simply for being Jewish; and torture was routinely used to extract "confessions." Over the years, the inquisition, which operated with Papal consent, spread to many countries.
In 1481 the Inquisition began to function in Spain to expose the secret Jews, known as the Anusim or Marranos. This Inquisition was anti-Jewish more than in any previous countries. The first public sentencing and burning alive of six marrano men and one woman by the Spanish Inquisition was held on this date in Seville in Southern Spain.
Following the start of the Spanish Inquisition many Jews fled Spain (see "Today in Jewish History" for Sivan 4).
