French diplomat and writer who encouraged the Franco-Russian alliance before and during World War I.

Paléologue entered the diplomatic service at an early age and went successively to Tangier, Rome, Germany, Korea, and Bulgaria. He became in 1909 deputy director and in 1911 director of affairs in the foreign office. Shortly before the outbreak of World War I, Paléologue was appointed ambassador to St. Petersburg, and he retained this post until the Bolshevik Revolution in 1917. During the war he consolidated the Franco-Russian alliance and helped to ensure effective military action on the part of Russia. In 1920 he was secretary-general of the ministry of foreign affairs.

Paléologue published in 1921–22, under the title of La Russie des Tsars pendant la grande guerre (“Tsarist Russia During the Great War”), records of his diplomatic experiences in St. Petersburg. He also wrote critical works on Vauvenargues and Alfred de Vigny (1890) and several novels. He was admitted to the French Academy in 1928.
