Edward Teach (c. 1680 – 22 November 1718), better known as Blackbeard, was a notorious English pirate who operated around the West Indies and the eastern coast of the American colonies. Teach captured a French merchant vessel, renamed her Queen Anne's Revenge, and equipped her with 40 guns. He became a renowned pirate, his cognomen derived from his thick black beard and fearsome appearance; he was reported to have tied lit fuses under his hat to frighten his enemies.
Not all Pirates were Criminals. Sometimes it depended on your point of view. During wartime, nations would often issue Letters of Marque and Reprisal, which allowed ships to attack enemy ports and vessels. Usually these ships kept the plunder or shared some of it with the government that had issued the letter.
