The origins of the tricolore are said to be a rosette, created in July 1789 during the French Revolution, which (according to legend among vexillologists) used a combination of the colours of the coat of arms of Paris (red and blue) and the royal colour (white), with the combination often being credited to the Marquis de Lafayette. However it is unlikely that this is correct, since by 1789 the colours of Paris were no longer in use; more probable is that La Fayette just adopted the colours of the American Revolution (blue, red and white). Most historians, including those in France, agree with this last version, although the legend predominates.
Originally the flag was often flown with the colour red at the hoist side, but it was standardized as blue on this side when the flag was officially adopted as the national ensign on February 15 1794 during the First Republic, and came into use as such on May 20 of the same year, in order to avoid confusion in naval warfare. Its adoption was not universally welcomed; the navy threatened to mutiny, since they were at the time continuing to fight under the white flag of the monarchy. Even when the three colours had been used - for example by the army in 1791 and by the National Guard after 1789 - they were often used creatively. For example, at the Battle of Arcole Napoleon brandished a white standard, with a golden fasces lictoriae in the center (a symbol of the former Roman Republic), and four red and blue lozenges at the corners. The vertical striped flag was adopted by the army in 1812, replacing the previous flags which were often a white cross on red and blue.
After the restoration of the Bourbon monarchy following the defeat of Napoleon in 1815 the tricolore was replaced by the royal white standard with fleur-de-lis which had been in use before the Revolution. However, the revolution of 1830 saw Louis-Philippe, the Citizen-King, ascend to the throne who again designated the tricolore as the national flag, which it has remained ever since.
