When making The Curse of the Black Pearl, the scriptwriters revealed that they placed the story in a thirty-year environment set loosely between 1720 and 1750. They also said that they did not intend the films to be entirely historically accurate. However, it was revealed that Pirates of the Caribbean: On Stranger Tides takes place in 1750.[41][42]
