Portugal followed suit in December 1496. However, those expelled could only leave the country in ships specified by the King. When those who chose to leave the country arrived at the port in Lisbon, they were met by clerics and soldiers who used force, coercion and promises to baptize them and prevent them from leaving the country. This episode technically ended the presence of Jews in Portugal. Afterwards, all converted Jews and their descendants would be referred to as New Christians or Conversos, and those were rumoured to practice crypto-Judaism were pejoratively labelled as "Marranos". They were given a grace period of thirty years during which no inquiry into their faith would be allowed. This period was later extended until 1534. However, a popular riot in 1506 resulted in the deaths of up to four or five thousand Jews, and the execution of the leaders of the riot by King Manuel. Those labeled as New Christians were under the surveillance of the Portuguese Inquisition from 1536 until 1821.
