The pirate known as Blackbeard terrorized the Atlantic coast of North America in the early 1700s.In a few months, the United States Supreme Court will hear a case related to Blackbeard's ship.The case involves a filmmaker who claims the rights to images of the ship belong to him, not the state of North Carolina.Here is what happened. Back in 1718, Blackbeard was sailing a ship named the Queen Anne's Revenge, after a former queen of England.One day the Queen Anne's Revenge and a smaller ship went into a harbor now known as Beaufort Inlet, in North Carolina.The water was not very deep, and the ships ran into the sand. (Blackbeard may have grounded the ships on purpose, but that is another story.)Blackbeard abandoned the Queen Anne's Revenge, along with a number of its crew members. He and a few of his favorite pirates escaped with valuable treasure.A few months later, Blackbeard was killed by British forces.And, in time, the Queen Anne's Revenge disappeared under the water.
