Coridanite Civil War
The Coridanite Civil War was civil conflict in the 2150s between the government of Coridan and a rebel faction, as well as a proxy conflict between Vulcan and the Andorian Empire.
In October, 2151 United Earth was briefly pulled into the conflict when Jonathan Archer and T'pol, captain and first officer of the Starfleet vessel Enterprise NX-01 respectively, were kidnapped by the rebels and held for ransom. (ENT: "Shadows of P'Jem")
