Who Were the 'Sea Dogs'? English Captains Who Challenged Spanish Naval Dominance

The Sea Dogs were 16th–17th century English privateers and naval commanders authorized by the Crown (letters of marque) to raid Spanish shipping and ports in the Caribbean and Spanish Main. They weakened Spain's treasure fleets and projected English power.

Famous Sea Dogs:

• Sir Francis Drake: Circumnavigated globe, raided Pacific coast, defeated Armada.
• Sir John Hawkins: Slave trader, naval reformer, treasurer of the navy.
• Sir Walter Raleigh: Explorer, Roanoke colony sponsor, privateer.

They were part state-sanctioned warriors, part pirates—blurring the line in the Anglo-Spanish conflict.
