Blackbeard

Blackbeard, also known as Edward Teach, was a notorious English pirate in the Caribbean Sea during the early 18th century. He appears in Pirates of the Caribbean: On Stranger Tides, played by Ian McShane, as the first historical pirate to appear in the Pirates of the Caribbean films.

History
Edward Teach was most likely born in Bristol, England. Little is known about his early life, but in 1716 he joined the crew of Benjamin Hornigold, a pirate who operated from the Caribbean island of New Providence. He quickly gained his own ship, Queen Anne's Revenge, and from 1717 to 1718 became a notorious and feared pirate. His cognomen was derived from his thick black beard and fearsome appearance; he was reported to have tied lit fuses under his hat to frighten his enemies. After separating from Hornigold, Teach formed an alliance of pirates, and with his cohorts blockaded the port of Charleston, South Carolina. After successfully ransoming the port's inhabitants, he ran his ship aground and then accepted a royal pardon. He was soon back at sea however, and attracted the attention of the Governor of Virginia, Alexander Spotswood. Spotswood arranged for a party of soldiers and sailors to find and capture the pirate, which they did on November 22, 1718. During a ferocious battle, Teach was killed by a small force of sailors led by Lieutenant Robert Maynard.

On Stranger Tides
In Pirates of the Caribbean: On Stranger Tides, he has a daughter named Angelica(who has not appeared in history). Blackbeard is in search for the Fountain of Youth, because he wants to achieve immortality.
