Détente (a French word meaning release from tension) is the name given to a period of improved relations between the United States and the Soviet Union that began tentatively in 1971 and took decisive form when President Richard M. Nixon visited the secretary-general of the Soviet Communist party, Leonid I. Brezhnev, in Moscow, May 1972.
He used diplomatic maneuvering alliances to increase French territory and centralize its government.
