The document summarizes the Anglo-Spanish War from 1585-1604. It describes how tensions arose between England and Spain due to privateering against Spanish ships. England sought to break Spain's monopoly on Atlantic trade. In 1585, the Treaty of Nonsuch was signed, which Spain saw as a declaration of war. In 1587, Queen Elizabeth had Mary Queen of Scots executed in retaliation. Spain then planned an invasion of England with the Spanish Armada in 1588. However, the Armada was defeated by storms and the English navy. Though Spain rebuilt its navy, the war did not officially end until the Treaty of London in 1604.
