The situation of Communist Party of Bohemia and Moravia (CPBM) is in the context of formal Central and East European satelites of Union of Soviet Socialist Republic to a great extent especial. In addition to the Czech Republic only in Belarus and partly in Ukraine there were no consistent transformation of former state-party into socialistic or social-democratic party. Czechoslovak communist party did after the fall of communist non-democratic regime at the end of 1989 precipitous progress, where after four years in the 1993 was affirmed a neocommunist party line. There is analysed one out of many indicators of the realization of the communist party reform in the paper CPBM and its Attitude towards own History namely the attitude towards own history, or towards history of Czechoslovakia under rule of communist party. For the record just obscure attitude towards history is one of the most important reason of informal exclusion CPBM out of chances to forme the executive coalitions.
