From Tikiland Trading:

"Sometime in the 17th century, pirates started using the recognizable skull & crossbones as a signal to their victims that they’d be merciless. What was believed to originally have dawned as a symbol on a flag though, has much deeper, and darker, roots.

Buried deep in pirate lore, a legend has existed that the first pirates did more than board and loot their victims vessels - they’d debone the captain of each ship, and display their skull and bones at the entrance of ports the pirates controlled.

While not many have been found, the legend of the Jolly Roger is true.

Over the last few hundred years, several of these Jolly Rogers have been unearthed and coveted in private collections, but hadn't been displayed publicly - until now."
