Pirates sail around the oceans, stealing from other ships. This is called piracy and is still common to this day. The captain of a pirate ship was typically the strongest fighter and one the men could trust. Pirate ships would often take on outcasts from society to join their crew. The skull and crossbones design on the pirate's hat is known as the Jolly Roger. The pirate in the picture has most of the features that pirates in modern movies and cartoons have: a parrot, a wooden leg, a hook hand and an eyepatch. In reality, with the conditions found on ships in the 1600s, a pirate that suffered such injuries in battle would have died from infection.
