Flag of Prague with Coat of Arms
Until 1784 when the four Prague cities were united: Staré Město, Nové Město, Hradčany and Malá Strana, each of them used its own coat of arms. United Prague adopted the coat of arms of Staré Město as the seat of the Magistrate. Through the years the coat of arms was slightly changed, the present form was established in 1991.
The hand with the sword was added by Ferdinand II as acknowledgement for Prague to a successful defence against the Swedish army in Thirty Year War.
This flag is sometimes confused with the traditional flag of Moravia. The colours used on the flags are simply “coincidental” and based on the heraldic rules used when making flags from the colours of coat-of-arms. Other than the colours, they are not related.
