The Hub's central council was founded at the end of the Great Merchant Wars in 2128 as a result of the negotiations between Roy Greene and the various merchant factions. The council consisted of two representatives from each other Hub caravan parties: The Water Merchants, Crimson Caravan and the Far Go Traders and was presumably chaired by the current town sheriff; each of which would have been the descendants of Roy Greene. In 2161 his grandson Justin Greene is sheriff. The council's job was to maintain the status quo of the Hub, and help mediate any disagreements between the various merchant factions.
The Hub's central council is mentioned in the original Fallout.
