Why Are In Society, Creoles Are Mixed People But Throughout Time In Louisiana They Were French/spanish Whites?

I would like to know how did Creole go from talking about whites of French/Spanish heritage to half black mixed people? All throughout Louisiana’s history (except for today) Creoles were white people in New Orleans from Latin roots. All the fancy Creole restaurants in New Orleans reflect thier food not the black creoles. So how did this happen? Also I understand that anything or anyone from New Orleans is Creole. Oh I’m from New Orleans by the way. Spanish/French heritage.

What’s The Difference Between Creoles And Cajuns?

I was bored the other day and I got wondering about this. What the heck is the difference between Creoles and Cajuns? And please note I’m talking about the cultures, NOT the food.
