Bartholomew Roberts was a man who lived a long time ago, in the 1700s. He was a pirate who sailed on a big ship with a crew of other pirates. Roberts was very good at being a pirate and he became famous for it.
Roberts and his crew would go around on their ship and steal things from other ships. They would take things like gold, silver, and other valuable items. Sometimes they would even capture the other ships and make the people on them become pirates too.
One of the things that made Roberts different from other pirates was that he cared about rules. He made his crew follow a set of rules that he called the "Articles of Agreement." These rules were like laws that the pirates had to follow, and they helped to keep the crew in line and make sure everyone was treated fairly.
Roberts also had a very fancy ship that was painted black with gold trim. It was called the Royal Fortune and it was one of the fastest and most well-armed ships on the seas. Roberts was able to use his ship and his crew to become one of the most successful and feared pirates of his time.
Despite his success, Roberts had a very short career as a pirate. He was only a pirate for about three years before he was killed in battle. But his legacy lived on and he is remembered as one of the greatest pirates in history.
