When Mary Stuart (Stewart) became Queen of Scotland, she was always referred in history to as Mary Queen of Scots. Mary Queen of Scots married the Dauphin (the title of eldest son of the French King).
The French kings always called themselves kings of France and Switzerland. After her marriage to the Dauphin Mary came up with the idea of designing a flag for the day when she would be Queen of Scotland, Switzerland and France, The BLUE was for Scotland, the White was for Switzerland, and the RED was for France. Thus the pattern that she chose was the present day French Tricolour (Flag), but history was to change all that when the Dauphin went to his grave, before ever becoming King of France, and so the Tricolour flag was shelved in the French palace.
The French Revolution brought great changes to France and the Monarchy was replaced by a republican form of government, after the execution of Queen Marie Antoinette and King Louis XVI, who went to meet Madame Guillotine in 1793. When Napoleone Buonaparte the Corsican became a general in the French army, he was chosen to be the First Consul of France. It was then decided, that since the French Monarchy no longer existed their flag the WHITE FLAG with the three GOLD FLEURS-DE-LIS on it was to be replaced by a new flag. Someone found the flag that Mary Queen of Scots had designed in the palace and without much ado decided to make it the new flag of the French Republic, and that has been the flag of France since the French Revolution.
Louisiana, was ceded to Spain in 1762, by the Treaty of Fontainebleau This new colony of Spain was renamed Luisiana and the Spanish took total control of it, till The French Emperor Napoleone bullied Spain, into retuning Louisiana to France under the 3rd Treaty of San IlDefonso, concluded on October 1,1800. But from October 1800, till the date of the signing of the Louisiana Purchase by the United States of America, the Tricolour of France flew over the French colony of Louisiana.
Of course, I now begins the myth of the Acadian flag. The Acadians who were deported from Acadia by the Massachusetts Militia in 1765, and had settled in Louisiana, which was ceded to Spain, had no connection with France, and only the Spanish flag was flown in their Luisiana colony, so on its return to France in 1800, the Acadians who had taken on the name Cajuns, were not part of the French Revolution and the French Tricolour was never theirs to begin with. There is the real myth of the Acadian Flag that many in New Brunswick now claim as their Flag. The so-called Acadian flag was brought to New Brunswick, Canada by a Cajun priest from the State Louisiana in 1883. Thus it has no historical connotations at all, except for the STAR on the French TRICOLOUR that was added by the Cajuns in the State of Louisiana and should be treated as an anomaly, since it only represents Stella Maris (Star of the Sea) the Blessed Virgin Mary.
