Francis Drake is knighted by Queen Elizabeth I for completing a circumnavigation of the world.

Sir Francis Drake was an English explorer and privateer best known for making the second circumnavigation of the world in a single expedition between 1577 and 1580. He is also known for participating in the early English slaving voyages of his cousin, 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.

Elizabeth I was Queen of England and Ireland from 17 November 1558 until her death in 1603. She was the last and longest reigning monarch of the House of Tudor. Her eventful reign, and its effect on history and culture, gave name to the Elizabethan era.

Francis Drake's circumnavigation, also known as Drake's Raiding Expedition, was an important historical maritime event that took place between 15 December 1577 and 26 September 1580. The expedition was authorised by Queen Elizabeth I and consisted of five ships led by Francis Drake. Termed a 'voyage of discovery', it was in effect an ambitious covert raiding voyage and the start of England's challenge to the global domination of Spain and Portugal.
