Sir Walter Raleigh (1552-1618) was an English adventurer, writer and nobleman. After growing close to Elizabeth I during his time in the army, Raleigh was knighted in 1585 and became captain of the guard. During Elizabeth’s reign, Raleigh organized three major expeditions to America, including the ill-fated Roanoke settlement. He later drew the queen’s wrath and was imprisoned in the Tower of London. After Elizabeth’s death in 1603, Raleigh was implicated as a enemy of her successor, James I and given a death sentence. The sentence was commuted, and Raleigh was freed to lead an expedition to the New World, but its failure sealed his fate.
