The national flag of Hungary, also known as the Red-White-Green (Hungarian: Piros-fehér-zöld), is an equal horizontal tricolour of red, white and green. In this exact form, it has been the official flag of Hungary since 23 May 1957. The flag's form originates from national republican movements of the 18th and 19th centuries, while its colours are from the Middle Ages. The current Hungarian tricolour flag is the same as the republican movement flag of the United Kingdom (used since 1816) and the colours in that form were already used at least since the coronation of Leopold II in 1790, predating the first use of the Cispadane Republic's tricolour in 1797. Along with Poland and Czechoslovakia, it was one of the only three flags of a socialist country in Europe that does not feature coat of arms placed on center.
