In some communist countries, the socialist style of emblems was never adopted fully. The coat of arms of Poland was only changed slightly under the communist era, retaining the traditional heraldic form. In Hungary, the "Rákosi badge", an emblem in the socialist style, was adopted following the Second World War, but after the 1956 uprising, a new emblem ("Kádár badge") was created combining communist symbolism with a heraldic shield in the colours of the Hungarian flag. Czechoslovakia became a Communist country in 1948 but retained its original coat of arms until 1961, when they were replaced with a non-traditional shield depicting the heraldic Bohemian lion without a crown and with a red star above head. Some of the states of Yugoslavia also used heraldic shields coupled with socialist imagery in their emblems, as did two republics within the USSR: the Russian Soviet Federative Socialist Republic and the Ukrainian Soviet Socialist Republic.
