The Lisbon massacre (alternatively known as the Lisbon pogrom or the 1506 Easter Slaughter) took place in April, 1506, in Lisbon in the Kingdom of Portugal. A crowd of Catholics, and foreign sailors who were anchored in the Tagus, persecuted, tortured, killed, and burnt at the stake hundreds of people who were accused of being Jews, and consequently deemed guilty of deicide and heresy. This incident took place thirty years before the establishment of the Portuguese Inquisition and nine years after the Jews were expelled in 1496 and forced to convert to the Catholic Church in 1497, during the reign of King Manuel I.
