The flag of Quebec, called the Fleurdelisé, was adopted for the province by the government of Quebec, during the administration of Maurice Duplessis. It was the first provincial flag officially adopted in Canada, first shown on January 21, 1948, at the Parliament Building of the National Assembly in Quebec City. Quebec's Flag Day-January 21-commemorates its adoption each year, though for some time it was celebrated in May. At least one parade marked the flag's 60th anniversary in January 2008.
The Fleurdelisé takes its white cross from the ancient royal flags of France, and its white fleurs-de-lis and blue field from a banner honouring the Virgin Mary reputedly carried by French-Canadian militia at General Louis-Joseph de Montcalm's victory at Carillon.
Contrary to popular belief, the white fleurs-de-lis are not taken from the banner of the kings of France, who used golden ones. The white fleurs-de-lis on Quebec's flag are symbols of purity, which originally represented the Virgin Mary. The flag is blazoned Azure, a cross between four fleurs-de-lis argent.
