highest summit (23,406 feet [7,134 metres]) of the Trans-Alai Range on the frontier of Kyrgyzstan and Tajikistan. Once thought to be the highest mountain in what was then the Soviet Union, Lenin Peak was relegated to third place by the discovery in 1932-33 that Stalin Peak (after 1962 called Communism Peak; now Imeni Ismail Samani Peak) was higher and by the finding in 1943 that Victory Peak was also higher.
