Ladislav Kopriva was a Czechoslovak Communist during the era of Gottwald, after the Czechoslovak Communist Party took control of the country during a 1948 coup. His position was Minister of National Security, and he was largely responsible for a series of purges of party members, such as Czech Vice Premier Rudolf Slansky, stating that "Our Czechoslovak traitors . .. can be compared with Russia's Trotsky ... Our conspiracies are not extraordinary, but only further evidence that our country is subject to the same laws of socialistic development as the Soviet Union."
Kopriva soon fell out of favor; he was "voluntarily" relieved in late January 1952, to be replaced by Karol Bacilek, who would initiate yet more purges.
Like many high Communist officials out of favor, he was soon the scapegoat of many a mistake; in April 1963 he was expelled from the party because of his role in the purges after the findings of the Kolder Report, which partly rehabilitated many of those purged.
