The Czechoslovak passport was issued to citizens of Czechoslovakia for international travel. After Czechoslovakia split into the Czech Republic and Slovakia, the two countries started issuing their own passports.
In autumn 1951, however, the government mandated that all passports be confiscated, necessitating them to be sent to the Ministry for State Security in Prague. This move left thousands of Czechoslovaks around the world effectively stateless as their documents were confiscated by their local embassy/consulate-general. Thereon, passports were only issued to people who the Communist government saw fit to possess one. The Czechoslovak ambassador in the Soviet Union, Bohuslav Laštovička, protested the sudden change in policy.
Travelling outside of the Eastern Bloc became a near-impossibility as Czechoslovak identity cards were only valid for travel inside the Iron Curtain and obtaining a passport through legitimate means was practically impossible. In 1963, however, Czechoslovak citizens were given authorization to visit relatives in the West, and subsequently, the 1965 Act No. 63 on Passports made for a more liberal passport issuance regime.
