Communist Party of Slovakia
In August 1991, upon the request of SDL, the party mutated into the Federation of the Communist Party of Bohemia and Moravia and the Party of the Democratic Left ("Federácie KSČM a SDĽ"). KSČM unsuccessfully appealed to two Slovak communist splinter parties, the Communist Party of Slovakia – 91 (KSS '91) and the Union of Communists of Slovakia (ZKS), to join the Federation. At the first SDL congress in December 1991, SDL formally withdrew from the Federation with the KSČM. The Federation was formally declared dissolved in April 1992.
