The Faction was a group that managed the supernatural community in New Orleans. They represented the four main species that reside in the French Quarter: vampires, witches, werewolves, and humans. After the Original hybrid Klaus returned to the city and took control, the Originals were also represented in the Faction as well.
The Faction was created by Klaus at some point after he and his family arrived in New Orleans in the early 18th century. When the Faction was created, it was composed of pirates and corrupt politicians, which remained more or less the same in the centuries after its creation. Decades after Klaus and his siblings were forced to flee from New Orleans, the Faction, at the time led by Father Kieran O'Connell, established a new rule that the organization would only be run by humans, though this rule was ultimately changed to welcome representatives of all five supernatural species in Season One of The Originals.
In Fruit of the Poisoned Tree, Niklaus Mikaelson approached the group in the middle of one of their meetings and remarked that he had created the Faction three hundred years prior. Father Kieran informed him that the Faction was now human-only, and that no vampires-- and especially no Originals-- were allowed to be members. Klaus revealed that he had come to ask them to use their resources to track down the witch Agnes, who had attacked the mother of his child with the Needle of Sorrows via Sophie Deveraux, who was magically linked to her. He then took great care to mention to Kieran that Agnes was also the witch who was responsible for hexing his nephew Sean, which caused him to lose his mind and murder his fellow seminary students in the church before finally killing himself. Kieran, desperate to avenge his nephew, agreed to Klaus' terms, but only because he wanted to deal with Agnes himself, and the Faction eventually found Agnes' address, which was given to Kieran and Klaus.
In Reigning Pain in New Orleans, all of the members of the Faction, including the mayor and the police chief (and with the exception of Kieran, who was not let in on the plan), put a hit out on the vampires as a warning to the new king, Klaus. This resulted in the vampires' hangout, the Pit, being attacked in a drive-by shooting, and several vampires dying from the subsequent sunlight exposure after the windows were shot out. Furious at this open attack on their people, Klaus and Marcel confronted the Faction at Rousseau's, where Kieran was already shouting at the rest of the members for attacking them behind his back. Klaus ultimately decided to kill all of them, except for Kieran, though he did argue that they were all important members of the community whose deaths would surely be questioned by the public. Klaus wasn't troubled by this statement, however, and reminded him that they were easily replaceable before instructing him to work to elect new and more trustworthy members.
In Moon Over Bourbon Street, Elijah, annoyed by Klaus' lack of motivation to run the city he worked so hard gain, decided to take matters into his own hands and run the city himself. He began by revamping the Faction, this time allowing the group to consist of a representative of each of the five species of New Orleans: he would represent the Originals, while Diego represented the vampires, Genevieve represented the witches, Francesca represented the humans (after Kieran was no longer fit to represent them), and Hayley represented the werewolves. There was much arguing between the representatives of the newly-created factions, but after a party at the Mikaelson compound where all of the different members could mingle together, they finally managed to agree to a new peace treaty, which they all signed in a mixture of their own blood. Elijah had Klaus sign the treaty as well, but Klaus wasn't a member of the Faction at the time, as he didn't believe that peace could exist between the different supernatural species in the city.
In The Battle of New Orleans, Francesca and her brothers revealed themselves to be untriggered werewolves who had been living under the guise of being human for decades. They then stole the moonlight stones that were meant for the Crescent Clan and killed their bodyguards, triggering their transformations and giving them the power to stage a coup to take control of the city from the Originals. Afterward, the Faction was more or less disbanded, as the peace treaty had become null and void with the Guerrera's tyrannical rule over the city. However, despite the Faction no longer existing formally, the birth of Klaus and Hayley's daughter Hope has led the Mikaelson family (including Hayley) to want to continue the Faction's mission of keeping the peace between the supernatural factions, so that the city can become safe for Hope and she can finally return home to her parents where she belongs.
