Slavery is the term used for the act of enslaving another person against their will, forcing them to work for their "master" and treat them like property of their "master" instead of a normal person.

Other CasesEdit

Practice of SlaveryEdit

Hancock Slave Mark

Hancock shows the mark of slavery which was branded upon her back.

Though slavery was prohibited by the World Government over 200 years before the current storyline, it still survives in certain places in the world, Sabaody Archipelago included. It is implied that the World Government receives bribes in exchange for ignoring the slave trade. The World Nobles practice slavery, using wanted pirates, other people and races as servants, trophies and "pets". To mark them as slaves, the Celestial Dragons brand them with the symbol called "The Hoof of the Soaring Dragon" (天駆ける竜の蹄 Ama Kakeru Ryū no Hizume?, FUNimation subs translate this as the Claw of the Celestial Dragons), forever marking them as "less than human".

Slaves are treated particularly horribly. Owners, particularly Celestial Dragons, would purchase them to work them down to the bone, threatening them with death for failure and opposition of any kind. Koala was so traumatized that she continued her slavering personality after her freedom. In fact, several slaves were tortured in gruesome manners simply to entertain the owners; some who are dismissed would end up taking their own lives to spare themselves of the misery, while others would have their personalities distorted to either continue acting as slaves or come to hate the world.[2]

Many slaves were once infamous people. Some have bounties of more than Beli50,000,000 and some are just wanted by buyers because of their species.

Slave OwnersEdit

Aside from the World Nobles, other people can also own slaves, if they were to buy it at certain auction houses that are (secretly) authorized by the World Government. Such an example can be Tequila Wolf, where they forced many slaves to build a bridge for 700 years.

Helping SlavesEdit

Unfortunately, the fact that no one can harm a Celestial Dragon or stand up to them means that no one can help a slave in need, or else they would risk certain death; however, brave people such as Fisher Tiger or Monkey D. Luffy may be immune to the intimidation. Aside from the "Hoof of the Soaring Dragon", the slaves also wear a Bomb Collar around their necks. If the prisoner attempts to escape from the Celestial Dragons, the collar explodes, heavily injuring (if not directly killing) the slave.

Bomb CollarEdit

Dias's Collar Explodes

Devil Dias' collar explodes.

The bomb collar is a device strapped around the neck of slaves. They are connected to a chain, which, if broken, will cause the collar to explode, strong enough to cause severe burns on the victim. Their purpose is to prevent slaves from attempting to escape, and only the key or a highly skilled person is able to unlock it. It first appeared in Chapter 497 and Episode 391, the collar being on Devil Dias.

Selling SlavesEdit

The Shichibukai Donquixote Doflamingo owned the Auction House before handing it over to his subordinate Disco. To hide the fact that slavery still exists, the sign on the door to the Auction house reads "Public Employment Security Office", a euphemism also used by the authorities to allow them to ignore this blatantly criminal enterprise.

Slave Price List

The slave price list.

There is also a list of how much a slave can sell for, depending on what kind of slave the person is. The current starting auction prices[3] is as follows:

  • Male: Beli50,000,000+
  • Female: Beli10,000,000+
  • Female: Beli70,000,000+
  • Male: Beli1,000,000+
  • Parted female: Beli10,000,000+
  • Devil Fruit users: Market price
  • Other rare species: Market price

Known Locations of SlaveryEdit

Sabaody Archipelago is a place where slavery is heavily enforced by sellers. Another known location is Tequila Wolf, where slaves were forced to build a bridge that connects the islands in the East Blue. It had been under construction for over 700 years, but was still incomplete due to the scale of the work involved, and may remain like that after all the slaves are freed by the revolutionaries. Also, Nico Robin was the newest slave there, after being teleported there by Bartholomew Kuma, and was only a slave for a short period of time.


It is unclear when slavery started, but it has been going on for more than seven hundred years because the people of Tequila Wolf had been building the bridge for seven hundred years.

Robin told Nami that slavery was a fearful pastime of humans, reminding people at present times how fearful and cruel people were in the old days. Also, Boa Hancock and her sisters were once slaves of the World Nobles, and they suffered greatly.

Donquixote Ancestor's Cruelty

The Donquixote king enslaving the Tontatta Kingdom dwarves.

Eight hundred years ago, the Donquixote Family used the dwarves of the Tontatta Kingdom for slave labor for their strength and gullibility. After the family left for Mariejois, the first king of the Riku Family made amends for the dwarves for the horrible treatment the preceding family had caused by granting them rights to take whatever resources they please.[4] Upon Donquixote Doflamingo ousting the Riku Family and retaking the throne in his family's name, he reestablished his clan's practice of using dwarves for slavery.[5]

Boa Hancock told Luffy the story of Fisher Tiger, who broke into Mariejois and freed hundreds of slaves from the Celestial Dragons. He, being a fishman, took many fishmen and formed the Sun Pirates, with Jinbe and Arlong included. Fisher then took the symbols of the Celestial Dragons that was marked on the Fishmen and transformed them into a symbol of the Sun Pirates, a sun. With the symbol modified, the Marines did not have evidence of who is a liberated slave.

Current EventsEdit

As seen in Nico Robin's cover story from Tequila Wolf, the Revolutionary Army arrived and liberated all slaves including her.

Two Years LaterEdit

After the timeskip, the Human Auctioning House has fallen into disarray and its owner, Disco, is now a vagrant.[6] Although as easily surmised and then directly stated by Caribou,[7] the slave trade lives on implying that this is not the only auction house.

Anime and Manga InfluencesEdit

Slavery was a huge trade during the real world's own Pirate Age. The slaves were often of African origins and had traveled across sea in appalling conditions with many dying along the way. The ones that survived the journey often ended up living a life of misery and abuse, sometimes in conditions not much better then the ones they traveled across the sea in. The branding of slaves with the owner's mark was also practiced in the real world. Just as in the One Piece storyline, in many cases the marked slaves were no longer considered human beings.

Those slaves who ended up being sold often tried to escape; slave owners over time turned to putting traps around the edge of their property to prevent the slaves from leaving, much as the exploding collar on the One Piece slaves serves this same purpose. The slaves lucky enough to escape were unable to return home and escaping slavery was also a risky situation; when caught by the authorities, they were either being returned to their masters, or even put them to death for escaping. Those that were returned to their masters often faced serious punishment, usually beating or scourging, which could be so brutal that some slaves did not survive it. In the One Piece storyline, such a thing was seen with the Sun Pirates, where the Marines attacked Fisher Tiger demanding that he return the slaves he stole, even though it was impossible to tell who was a slave anymore.

As pirate crews raided ships at sea, it was not uncommon for those crews to come across slave ships. Some crews gave the slaves a chance to join the crew, these slaves often took up the offer as the life of a pirate was more often than not a better lifestyle than that of a slave. The slaves were often very thankful for their freedom and very loyal to the crews they joined. The recruitment of slaves into a pirate crew also led to a number of crews being multi-racial. In One Piece, Fisher Tiger himself was not against the idea of taking Koala on board his ship or returning her to her home island and even burned the "mark of the sun" onto her back, despite being a human. The crew itself consisted mostly of fishmen, but at least one merman was also known to be on board with the crew.


Donquixote Doflamingo at Age 8

Doflamingo believes the clothes make him look like a slave.

  • In the anime, when Donquixote Doflamingo was dressed by his parents into normal noble clothes (a simple light-colored dress shirt with a red cravat and blue pants), he detests it as he believes it make him look like a slave. This suggests that certain slaves of the Celestial Dragons wear normal noble clothes.[8]
