Sometime in the past, the inhabitants began to extract Dyna Stones using a secret method of excavation known only to the leader of the island.
Twelve years before the main storyline, the Marines hired a pirate fleet to attack the island in order to obtain the excavation method and the Dyna Stones, acknowledging them as a huge threat to world power balance. Thanks to Jeanne's mother, the war was averted, but she lost her life in a fight. The only survived pirate is Barbados.
Some time later the future leader and Jeanne's brother Isaac left the island in order to enlist in the Marine to pursue his justice ideals. He eventually lost faith in the Marine finding out the truth behind pirates'a attack to the island, but keep ranking up till the Prison Warden position, just to make return on the island, officially in order to monitoring the Dyna Stones excavation and sending informations to the Headquarter. He made build other two gaols (Aquamarine and Santa Maria), which brought richness to the people supporting Marine's domination, while the ones oppositing them got ostracized by various power abuse episodes, factually splitting the population in two factions: Pro-Marines and Anti-Marines. Jeanne eventually became the Anti-Marines' leader.
Isaac secretly began his revenge plan ten years before the main storyline, when he gathered a huge number of pirates in Tormaline, forcing them to build mechanic parts.
Some time before the main storyline, Isaac began spreading the rumour about a hidden treasure on the island, in order to gather several pirates to obstruct CP-0 agents' investigation and to draw Marine Admiral's attention.

Almost at the same time, the World Government began to seek information, sending Rob Lucci on the island. Germa 66 too got convoked on the island due to their interest into buying Isaac's robots.
The grown grudge between Pro-Marines and Anti-Marines lead the latters to ask for Revolutionary Army's help, but it is too late. Short later Sabo's arrival on the island, some Pro-Marines shoot on Anti-Marines and civil war spreads.
Jeanne is able to appease the civillian thanks to a message spred by the Radio Tower she assaulted with Straw Hat Pirates' help. Isaac decides to make his move invading the island with his robots, keeping busy both admirals Kizaru and Fujitora as Kuzan, Smoker and Tashigi. Luffy and Jeanne decides to reach Santa Maria to personally deal with Isaac, but Fleet Admiral Sakazuki gets in the way. Thanks to Sabo's intervention, both Luffy and Jeanne are able to reach the cannon that will send them on the Sky Prison.
On the Santa Maria, Isaac reveals his true intention: he wants to launch the prison on Mary Geoise, letting the Dyna Stones collected in there explode, destroying the Holy Land. After Isaac's defeat, the prison detonates far from Jail Island. The shockwave invests the island, inducing Marines to evacuate the residents.
