Jan Janszoon (Murat Reis the Younger)

Jan Janszoon of Haarlem, known after his conversion as Murat Reis the Younger (c. 1570–c. 1641), was a Dutch seaman turned Barbary corsair. Captured by Algerian corsairs off Lanzarote in 1618, he converted to Islam and took the name Murad, thereafter raiding European shipping from Algiers and the Moroccan coast. He helped found the independent Republic of Salé and served as its first president and commander.

In 1622 he docked at Veere under the Moroccan flag; Dutch authorities brought his wife and children to persuade him to abandon piracy, but he refused. On 20 June 1631 he led the sack of Baltimore in Ireland, carrying much of its population away into slavery.
