Sir Francis Drake (c. 1540 – 28 January 1596) was an English explorer and privateer best known for his circumnavigation of the world in a single expedition between 1577 and 1580. This was the first English circumnavigation, and second circumnavigation overall. He is also known for participating in the early English slaving voyages of his cousin, Sir John Hawkins, and John Lovell. Having started as a simple seaman, in 1588 he was part of the fight against the Spanish Armada as a vice-admiral.
