Who was the first territorial governor of Florida after its purchase by the United States?

The first territorial governor of Florida after its acquisition by the United States was Robert Duval. Florida was acquired through the Adams-Onís Treaty in 1819, and Robert Duval was appointed as the first governor when the territory was officially established in 1822. His role was crucial in laying the groundwork for the new territory's governance, implementing law and order, and facilitating settlement and development in Florida.

While Andrew Jackson played a significant role in the early history of Florida, including as a military leader during the First Seminole War and as a key figure in the territorial transition, he was not appointed as the territorial governor. Instead, his actions helped pave the way for the territorial governance that Robert Duval would later implement. The other names, Napoleon Bonaparte and Davy Crockett, do not relate directly to the governance of Florida during this period.
