The Federation-Klingon War of 2267 was a brief conflict fought between the United Federation of Planets and the Klingon Empire in 2267. It was the result of the tensions built up during the Federation-Klingon Cold War. Captain James T. Kirk and Spock fought against Kor, son of Rynar to secure the planet Organia, which occupied a strategic location. The war abruptly ended when the native Organians imposed a peace treaty on both sides. (TOS episode: "Errand of Mercy")
