Did the french and indian war affect the growth and development of louisiana in 1763?

Yes, the Indian and French War affected the growth and development of Louisiana in 1763.  

Explanation:

Due to the Seven Year’s war between the Great Britain and France, France decided to give Louisiana to Spain to make Spain conflict from their side. They signed a “Family Compact” to ensure that Spain and France won’t fight with each other, secretly. The British found about their secret and attacked Spain.

So, in November 1762, France finally handed over Louisiana along with Isle of Orleans to Spain, stretching its hands for friendship. Finally, in 1763 the British officially handed over Louisiana’s ownership to Spain, ending the French and Indian War.
