Who was the first Spanish Governor of Louisiana who fled due to French resistance?

Don Antoine de Ulloa was indeed the first Spanish governor of Louisiana, appointed in 1766 after Spain acquired the territory from France. His governorship faced significant challenges, particularly due to resistance from the French settlers and local population who were unhappy with Spanish rule. Ulloa struggled to implement Spanish policies effectively and faced open opposition, which ultimately led to his departure from the colony in 1768. This flight was not just a strategic retreat; it was a response to a rebellion fueled by dissatisfaction over Spanish administration and economic policies. This context of political turmoil and the resistance he encountered underscore why Ulloa’s governorship was notably short-lived.

The other figures listed do not align with the specifics of the question. General Alexander O'Reilly succeeded Ulloa and was known for his efforts to restore order and integrate Spanish authority, while Pierre Le Moyne d'Iberville was a French explorer and not a Spanish governor. Antoine Crozat was a French proprietor and heavily associated with the early French colonization of Louisiana, again not fitting the criteria of a Spanish governor.
