Commemoration Day for the Victims of the Communist Regime is observed in the Czech Republic every June 27. This remembrance day honors individuals who died under the Communist regime in Czechoslovakia, which was marked by significant human rights violations following the Communist Party's seizure of power in 1948. The date was chosen to pay tribute to Milada Horáková, a political activist executed by the Communists on this day in 1950. Horáková, a member of the Constituent National Assembly, was arrested after the Communist coup and accused of plotting to overthrow the regime, leading to her death sentence. Established in 2004, this day serves as a solemn reminder of the repression faced by religious and human rights activists during that period.
