Slavery

Slavery is the term used for the act of enslaving another against their will and forcing them to work for their "master".

One Piece Slavey


In One Piece, slaves are used by the World Nobles, even though slavery itself was branded illegal years ago. To hide the continuing slavery that occurs, the Auction House that Donquixote Doflamingo owned was branded "Public Employment Security Office". Since no one would dare stand up to a World Noble, slaves seen at the hands of the World Nobles are not aided in any way.

All slaves are branded with the representation logo of the World Nobles; the hoof of the Dragon. These symbols are burnt into the skin so they remain there for the rest of the slave's life, labelling them forever as "less then human".

Another location connected with slavery is the island of Tequila Wolf, in the East Blue, where the enslaved inhabitants have been working on a bridge for the last 700 years. Nico Robin also became a slave on the island after being teleported there by Bartholomew Kuma.

History
It is unclear when slaver exactly started, but it exists since at least 700 years on Tequila Wolf in the East Blue. However the oldest slaves to date would be the Gorgon siblings. They were taken at the age of twelve, roughly about fifteen years ago. They were branded and thus became a "lesser" human being. Four years later a fishman named Fisher Tiger climbed the red line and successfully infiltrated Mariejois, freeing hundreds of slaves from the Tenryuubito.
