Marxist-Leninist party formed in 1921 once dominant as the "Communist Party of Czechoslovakia" (KSČ) in pre-Velvet Revolution Czechoslovakia. Party in its current form (since changing its name in 1990 after being declared a "criminal organization" and banned) remains the last of the 'unreformed' Communist parties in Europe. Party uses the emblem of the two red cherries with a green leaf, which has its origins in the French uprising called the 'Paris Commune' (March 18 to May 28, 1871) against the Adolphe Thiers government. Party had been chaired by Vojtech Filip since October 1, 2005. Filip resigned on October 9, 2021, after the party was booted out of parliament after elections held on October 8-9, 2021, the first time out of the legislature in its 100 year history [Komunistická strana Čech a Moravy (KSČM)].
