After his return to Kroměříž Čepička got involved in local administration, dealing brutally, quickly, and effectively with post war chaos. He married the daughter of Klement Gottwald, the leader of the Communist Party, who later became prime minister and President of Czechoslovakia. As a candidate of the Communist Party, Čepička was voted into parliament in the 1946 elections. In 1947, he was named into the position of minister of interior trade. After the Communist takeover of power in 1948, he became Minister of Justice. In this position he let the law system be dominated by the will of the Communist Party; a law prosecuting political opponents was approved and put into full force. In 1950, he was named head of the state commission dealing with churches. His task in this position was to suppress any sign of resistance from religious organisations, especially from the Catholic Church.
During 1950-56, Čepička served as Minister of Defence. According to historian Karel Kaplan, Čepička was ordered by Joseph Stalin personally to prepare the Czechoslovak Army for incursion into Western Europe area. The preparations included militarisation of the society, purges of those suspected of low loyalty to the new regime, salary rises of army officers, and growth in numbers of army personnel. While he was the Minister of Defence, he proposed the Hotel International Prague and envisioned a monument to the newly formed Fourth Czechoslovak Republic that would reinforce ties with the Soviet Union.
The Fall
After the death of Stalin and Gottwald in 1953 the prospect of immediate war lessened and Čepička's position became precarious. Leaders of the Communist Party were afraid of his political ambitions and rumours of his being homosexual did not help his popularity. Čepička was selected as a scapegoat for the cult of personality around Gottwald, dismissed from all functions in 1956 and put into low importance position as head of statepatent office. In 1959 he suffered a heart attack and was sent into comfortable retirement. Continuing liberalisation of political life made him a symbol of the past wrongs and in 1963 Čepička was expelled from the Communist Party for his role in the "deformations of the 50s". Čepička spent the rest of his life in retirement, never entered politics again, and died forgotten.
In fiction
In 1969 Miroslav Švandrlík wrote Black Barons, a satirical book officially published in 1990, after the fall of the Communist Party from power. The book and its sequels became popular and were followed by a film and TV series. The book subtitle "We waged war under Čepička" reminds us of the then Minister of Defense Alexej Čepička. One of the main characters in the book, major Terazky, is shown as a comical character, hopelessly trying to turn stupid army officers and bored conscripts into feared warriors, and this image of him as a clown underscores the absurdity of the socialist army.
