CSEMADOK was formed on March 5, 1949, in Bratislava as a part of the Czechoslovak National Front, an umbrella statewide organization.
The society organized cultural events, lectures and supported theater-, song- and dance groups.
During the Hungarian Revolution of 1956 the leadership supported position of Czechoslovak government toward the events; this resulted in decline of members (33,000 reported in 1957).
[1] In 1968, during the Prague Spring period, CSEMADOK supported the liberalization policies, tried to change into a political interest group and asked for more rights and privileges for the ethnic Hungarians.
After dissolution of Czechoslovakia (end of 1992) the organisation changed its name to Szlovákiai Magyar Társadalmi és Közmüvelödési Szövetség – Csemadok (Slovak: Maďarský kultúrny a spoločenský zväz na Slovensku, English: Hungarian Social and Cultural Association of Slovakia).
