1940s
The historical Democratic Party arose in 1944 during the Slovak National Uprising as a party for all non-Communist participants (i.e. the counterpart of the Communist Party of Slovakia). In the 1946 elections in Czechoslovakia, the party won as much as 62% of votes in Slovakia, but was liquidated in 1947-1948 by the Communists, who had a majority in the central government in Prague (because as opposed to Slovakia, it was the Communists who won the 1946 elections in Czechia). The rest of the party was transformed into the pseudo-party Party of Slovak Revival (Strana slovenskej obrody) within the see National Front (Czechoslovakia).
