Flag of France
|Design||A vertical tricolour of blue, white, and red. |
The tricolour flag is derived from the cockades used during the French Revolution. These were circular rosette-like emblems attached to the hat. Camille Desmoulins asked his followers to wear green cockades on 12 July 1789. The Paris militia, formed on 13 July, adopted a blue and red cockade. Blue and red are the traditional colours of Paris, and they are used on the city's coat of arms. Cockades with various colour schemes were used during the storming of the Bastille on 14 July. The blue and red cockade was presented to King Louis XVI at the Hôtel de Ville on 17 July. Lafayette argued for the addition of a white stripe to "nationalise" the design. On 27 July, a tricolour cockade was adopted as part of the uniform of the National Guard, the national police force that succeeded the militia.
A drapeau tricolore with vertical red, white and blue stripes was approved by the Constituent Assembly on 24 October 1790. Simplified designs were used to illustrate how the revolution had broken with the past. The order was reversed to blue-white-red, the current design, by a resolution passed on 15 February 1794. Despite its official status, the tricolore was rarely used during the revolution. Instead, the red flag of the Jacobin Club, symbolizing defiance and national emergency, was flown. The tricolore was restored to prominence under Napoleon.
When the Bourbon dynasty was restored following the defeat of Napoleon in 1815, the tricolore—with its revolutionary connotations—was replaced by a white flag, the pre-revolutionary naval flag. However, following the July Revolution of 1830, the "citizen-king", Louis-Philippe, restored the tricolore, and it has remained France's national flag since that time. 
The three colours are occasionally taken to represent the three elements of the revolutionary motto, liberté (freedom: blue), égalité (equality: white), fraternité (brotherhood: red); this symbolism was referenced in Krzysztof Kieślowski's three colours film trilogy, for example.
On the other hand, the French government website wrote that the white field is the color of the king, while blue and red were the colors of Paris.
Blue and red are associated with the Virgin Mary, the patroness of France, and were the colours of the oriflamme. The colours of the French flag may also represent the three main estates of the Ancien Régime (the clergy: white, the nobility: red and the third estate: blue).
