and Portuguese ships off the coast of West Africa. When the Anglo-Spanish Wars intensified after 1585, Elizabeth approved further raids against Spanish ports in the Americas and against shipping returning to Europe with treasure. Meanwhile, the influential writers Richard Hakluyt and John Dee were beginning to press for the establishment of England's own overseas empire. Spain was well established in the Americas, while Portugal, in union with Spain from 1580, had an ambitious global empire in Africa, Asia and South America. France was exploring North America. England was stimulated to create its own colonies, with an emphasis on the West Indies rather than in North America. Martin Frobisher landed at Frobisher Bay on Baffin Island in August 1576; He returned in 1577, claiming it in Queen Elizabeth's name, and in a third voyage tried but failed to found a settlement in Frobisher Bay. From 1577 to 1580, Francis Drake circumnavigated the globe. Combined with his daring raids against the Spanish and his great victory over them at Cádiz in 1587, he became a famous hero—his exploits are still celebrated—but England did not follow up on his claims. In 1583, Humphrey Gilbert sailed to Newfoundland, taking possession of the harbour of St. John's together with all land within two hundred leagues to the north and south of it. In 1584, the queen granted Walter Raleigh a charter for the colonisation of Virginia; it was named in her honour. Raleigh and Elizabeth sought both immediate riches and a base for privateers to raid the Spanish treasure fleets. Raleigh sent others to found the Roanoke Colony; it remains a mystery why the settlers all disappeared. In 1600, the queen chartered the East India Company in an attempt to break the Spanish and Portuguese monopoly of far Eastern trade. It established trading posts, which in later centuries evolved into British India, on the coasts of what is now India and Bangladesh. Larger scale colonisation to North America began shortly after Elizabeth's death. Distinctions England in this era had some positive aspects that set it apart from contemporaneous continental European societies. Torture was rare, since the English legal system reserved torture only for capital crimes like treason—though forms of corporal punishment, some of them extreme, were practised. The persecution of witches began in 1563, and hundreds were executed, although there was nothing like the frenzy on the Continent. Mary had tried her hand at an
