Vestian

Vestians are natives of the Vestios system. The Vestians settled several planets within their system, including Vestios Prime and Vestios II, all ruled by a Vestian Council.

There had been numerous conflicts between the Vestians and the Federation in the early years of the 23rd century. A treaty between the two in the 2310s ensured peace between the two for several years.

In 2320, a civil war broke out amongst the Vestians, involving rebels on Vestios II. These rebels attacked Federation ships, apparently in an effort to involve the Federation in the fighting. Toward the end of the war, a Starfleet ship patroling the border, the USS Aldrin, did destroy a rebel ship, and fired on an official military vessel. The Vestians opted to overlook these instances to avoid an interstellar incident.

The Vestians became members of the Federation in 2310. Ambassador Spock attended a conference on Vestios Prime in 2320 to mark the tenth anniversary of their membership. (TOS novel: Burning Dreams)
