On his return to Prague at the end of the war, Benes became the first foreign minister of the new state. From 1918 to 1935, he worked to strengthen the security of Czechoslovakia, the cornerstone of which was a 1924 alliance with France. In addition, he worked to cooperate with Romania and Yugoslavia, with the three states signing collective security arrangements that led to the so-called Little Entente. Benes was also a tireless advocate of the League of Nations, serving as League Council chairman five times. He secured a mutual security pact with the Soviet Union in 1935.
In December 1935, Benes succeeded Masaryk on the latter's resignation as president of Czechoslovakia. The one intractable problem he could not solve was that of the minorities in his nation. The Czechs were not even a majority of the population of the state, and there were serious problems with the Ukrainians, the Slovaks, and especially the Germans. Adolf Hitler pushed the demands of the latter from relief of grievances into annexation by the Reich of those areas in which Germans were a majority. Benes and his government went as far as they could without actually ceding territory, but at the September 1938 Munich Conference, the British and French agreed to Hitler's dismemberment of Czechoslovakia. A week later, Benes resigned and went into exile in France.
Benes became president of the Czechoslovakian government-in-exile in London in July 1940. He hoped to make his country a bridge between the East and the West, and he signed a 20-year treaty of alliance with the Soviet Union in 1943. He returned to Prague on 16 May 1945, stopping first in Moscow to confer with Josef Stalin.
Benes was reelected president in 1946, but his hopes of nonalignment ran afoul of the Cold War. The Soviets staged a coup d'état in Prague in February 1948, and Benes was forced to accept Communist control. Rather than agree to a new constitution that would legalize the Communist seizure of power, he resigned on 7 June 1948. He died in Sezimovo Üsti, Bohemia, on 3 September 1948. Annette Richardson
