In the world of One Piece, no organization is as powerful as the World Government, which was established around 800 years ago on the back of the defeat of the Ancient Kingdom and the death of Joy Boy at the hands of the 20 Kings. After the conclusion of the war that took place in the Void Century, the 19 Kings created the World Government and put down their weapons in front of the Empty Throne to swear an oath of equality. On this day, the World Government was created, and this organization has continued to evolve since.
