In the films, pirates have exciting and adventurous lives. But what was life actually like for an 18th-century pirate? Which aspects of the film pirate are real, and which are invented?
While film pirates are men in search of adventure, the average pirate was usually trying to escape from a difficult life. Some were ex-sailors who were treated poorly on their ships. Others were escaped slaves who wanted their freedom. They came from many different backgrounds. But on a pirate ship, equality was important. Men elected their captain and created the ship's rules together. The men also divided the income from stolen goods, and they shared these earnings fairly.
In films, pirates have chests full of gold and piles of money stolen from other people. However, it was far more common for pirates to steal things like cloth, spices, and even medicine. They often sold these things. Of course, purchasing stolen goods from pirates was illegal, but many people did it. Also, unlike film pirates, real pirates didn't bury their money, says Cori Convertito, who works at a maritime museum in the U.S. "They blew it as soon as they could on women and booze".
Film pirates often wear eye patches and have wooden legs. Many real pirates also looked like this. Why? One factor was the poor living conditions. "Life at sea was hard and dangerous, says David Moore, a maritime museum employee. Disease was also common. For these reasons, some pirates lost eyes and legs. But many pirates did one thing for their health: They wore earrings - just like in the films. They believed putting weight on the ears stopped seasickness.
