Vulcan - Andorian history Vulcan - Andorian history is marked with great tensions between the powers of and the Andorian Empire in the 22nd century . First Contact and Beginning of Hostilities . At first , relations between Vulcan and Andor were promising , but the Vulcan s believed that the Andorian s were duplicitous , wishing to only honor agreements that did not conflict with their interests . In the 1950s , the Vulcans were suspicious of the Andorians ' territorial and militaristic nature while the Andorians believed that the only thing keeping the Vulcans from invasion was the threat of mass retaliation . The class D planetoid , called Weytahn by the Andorians and Paan Mokar by the Vulcans , was terraformed and colonized by the Andorians and had a key strategic position on the frontier between Vulcan and Andoria . After the Andorians refused to allow the Vulcans to inspect the colony for an invasion force , the Vulcan High Command ordered the forced removal of all Andorian colonists . ( ) Cold War . The Vulcans and Andorians signed a peace treaty and the Vulcans put a satellite in orbit of Paan Mokar to see that the treaty was obeyed . The Vulcans also created a very powerful surveillance device under the ancient monastery of P ' Jem . The Andorians believed strongly in the existence of the listening device and occupied the monastery several times but leaving soon afterwards , not being able to prove its existence until they were assisted by the Human s of the starship . They later returned and bombed the monastery , though they gave the monks a chance to escape . ( ) Another conflict in the cold war was when Coridan , an inhabited planet rich in dilithium that was controlled by a corrupt government supported by the Vulcan High Command , was undergoing a civil war where the rebels were being supported by the Andorians . ( ) Soon afterward , an old conflict re - emerged . The Vulcan satellite detected the Andorians landing on Paan Mokar and occupying the settlement . The Vulcans retaliated and took control of half of the settlement . The Vulcans then offered a cease fire which Shran , the commander of the Andorian regiment , agreed to as long as Captain Jonathan Archer of the Earth starship " Enterprise " mediate the negotiations . The Vulcans and Andorians had reinforcements on the way , but , with some help from the Humans , they arranged a new , fairer treaty . ( ) The Andorians assisted the Humans during the " Enterprise " s mission in the Delphic Expanse when they planned to steal the Xindi weapon prototype . The Andorians really planned to steal the weapon for themselves to gain the advantage in the Cold War , but it was destroyed by the " Enterprise " . ( ) Battle of Andoria and End of Cold War . Minister V ' Las of the High Command , which had taken control of the Vulcan government , convinced the other ministers that the Andorians had recovered the Xindi technology . He used this fake evidence to convince the others that the best course of action was an invasion of Andoria . The Vulcans created fake warp signature s outside of Weytahn while a real fleet of twelve ships were amassed at Regulus , a star outside of the range of Andorian listening posts . The Andorians were only able to muster six ships and were aided by the " Enterprise " . After finding no Xindi technology on the Andorian ships , minister V ' Las was overthrown ( though the battle itself continued for sometime ; see Battle of Andoria ) and a new more peaceful government was installed on Vulcan , thereby ending the Vulcan - Andorian Cold war .
