Pirates of the 17th & 18th centuries often flew a black flag, indicating allegiance to no country. In the early 1700's, many began using emblems meant to cause fear, such as a devil with an hourglass ("time is running out"), or a skull and crossbones ("surrender or die"). The skull and crossbones came to be known as the Jolly Roger. Many pirates had their own unique design. Another tactic that was often used by pirates was to have a chest with several national flags. When approaching a target ship, they would fly the flag of a friendly nation to put them at ease, then raise the Jolly Roger once they got close. Sometimes the victims would surrender, or jump overboard, rather than engaging in battle; then the pirates could take the booty without a fight-- easy money!
