Parliamentary elections were held in Czechoslovakia on 30 May 1948. They were the first elections held under undisguised Communist rule; the Communist Party of Czechoslovakia had seized complete power three months earlier.
The Communists had become deeply unpopular, and all indications were that they would be voted out of office in the elections due in May. The endgame began on 13 February, when a majority of the cabinet demanded that Communist Interior Minister Vaclav Nosek stop packing the police with Communists. Nosek refused, and was supported by Prime Minister and Communist Party leader Klement Gottwald. On 21 February, 12 non-Communist ministers resigned, believing that President Edvard Beneš would side with them and force Gottwald to either back down, resign, or call early elections that the Communists would not have time to rig. Beneš initially supported their position, and refused to accept their resignations. By this time, however, Gottwald had dropped all pretense of democracy. He not only refused to resign, but demanded the appointment of a Communist-dominated government under threat of a general strike. His Communist colleagues occupied the offices of the non-Communist ministers.
Fearing Red Army intervention, Beneš gave way on 25 February and appointed a new government in accordance with Gottwald's demands. Communists and pro-Moscow Social Democrats held most of the key posts. Members of the other parties still figured, so it was still technically a coalition. However, all except Foreign Minister Jan Masaryk were fellow travellers handpicked by the Communists. On 9 May, a new constitution was approved by the now-subservient National Assembly. While it was not a completely Communist document, its Communist imprint was strong enough that Beneš refused to sign it.
