Captain William Rainsborough (11 June 1587 – 16 Feb 1642) was an English Captain and Vice-Admiral in the Royal Navy, English ambassador to Morocco and politician who sat in the House of Commons from 1640 to 1642.
On the orders of Charles I of England, Rainsborough led a successful naval expedition against the Barbary corsairs of Salé in North West Morocco in June 1637. His exploits were hailed in a court masque designed by Inigo Jones For his services to end white slavery Rainsborough was offered a hereditary knighthood, which he declined, and was presented with a Gold Chain and Medal by Charles I. Captain Rainsborough's Emblem was a Saracen's head crest. The Saracen Head as interpreted as 'the head of the foreigner'; the foreigner being the much-feared pirates of the north African coast. Usually referred to as Turks, these marauders were in the white slavery business. This emblem represented Captain Rainsborough's success at ending White Slavery against the Barbary pirates in Morocco in 1637.
