Mojave Boot-Riders

The Mojave Boot-Riders (simply referred to as the Boot Riders by members) were a nomadic tribe inhabiting the Mojave, before their evolution into the Chairmen.

Background
One of the many nomadic tribes that formed out of the ruins of the Old World, the Boot-Riders inhabited the ruins of Las Vegas. Their situation dramatically changed when they were approached in 2274 by a securitron. The tribesmen destroyed it in a "minute flat." The following day, twenty Securitrons approached them and they were forced to negotiate with Mr. House. In return for shelter, food, and medical care (all the things a nomad always needed), they would settled down, renovate The Tops, and work with Robert House to establish the city of New Vegas. Most of the tribe was against settling down, with the most vocal critics being its chief, Bingo. Benny, on the other hand, saw it as an opportunity.

The disagreement over this issue eventually led to a confrontation between Benny and Bingo. The latter challenged Benny to a ritual knife fight over the leadership of the tribe. The fight went down three days after House had made his proposal. Benny's superior skill with a knife left him as the victor and new leader of the tribe. The tribe moved to Vegas and began renovating the Tops, bringing it back to life. As they worked, a number of House's securitrons dropped off boxes with suits, ties, and wingtip shoes, together with a message from their employer announcing they were the Chairmen now. The tribe was in an uproar over the new name, but Benny used his authority to force them to accept it. As he put it, it was "ciao to the old ways" and "time to swing in style."

Appearances
Mojave Boot-Riders as such are mentioned in Fallout: New Vegas and actually appear only as the Chairmen. The actual Boot Riders before they became the Chairmen are shown in the All Roads graphic novel.
