During the Hussite Wars when the City of Prague was attacked by "Crusader" and mercenary forces, the city militia fought bravely under the Prague Banner. This swallow-tailed banner is approximately , with a red field sprinkled with small white fleurs-de-lis, and a silver old Town Coat-of-Arms in the centre. The words "PÁN BŮH POMOC NAŠE" (The Lord is our Relief) appeared above the coat-of-arms, with a Hussite chalice centred on the top. Near the swallow-tails is a crescent-shaped golden sun with rays protruding.
