2156–2160 - Earth–Romulan War - The Earth-Romulan War was the last major conflict between Earth and an alien species before the United Federation of Planets was formed and was mostly shown or discussed on Star Trek: TOS and Enterprise. The war lasted from 2156 to 2160, although tensions had been building during the early 2150s as Romulans sought to keep humanity from becoming a major galactic power. Open hostilities ended in 2160, when human, Vulcan, Andorian, and Tellarite forces allied to defeat the Romulans. The end of the war resulted in the creation of the Romulan Neutral Zone, and the four allied forces in the battle became the Federation's founding members.
2256-2293 - Federation-Klingon War - The outbreak of the war was marked by the Battle of the Binary Stars, which was provoked by T'Kuvma, a Klingon who rallied the Empire to a common cause as he had portrayed the Federation as an existential threat, whose space had encroached unacceptably close upon that of the Klingons. Even after the war, relations remained tense.

2340s-2367 - Federation-Cardassian War - During the war, both Cardassian and Federation forces battled for control over locations along the Federation-Cardassian border, but by the mid-2360s, the fighting had come to a stalemate, which led to the peace treaty and armistice being drawn up in 2367. The armistice created further problems however when it established a demilitarized zone along the border. During the creation of the demilitarized zone, a number of planets with both Federation and Cardassian colonies on them fell into dispute, giving rise to the formation of the Maquis.
