During the period of the Czechoslovak Socialist Republic, regular victory day parades were held by the Czechoslovak People's Army (ČSLA) in Letná. The first parade took place in 1951 and have since been held every five years on 9 May up until 1990. The parade also marked the Prague uprising. The last of these parades took place in 1985. "Kde domov můj" (the Czechoslovakian national anthem) was performed by the massed bands on parade before being followed by the "State Anthem of the Soviet Union". Parades were also held in Bratislava and Pilsen as well.
