What effect did the Adam-onis treaty have on filibusters?

The Adams-Onís Treaty of 1819, which ceded Florida to the United States from Spain, significantly impacted filibusters by legitimizing U.S. territorial expansion and emboldening private military expeditions into Spanish territories. It effectively reduced the perceived legitimacy of such ventures, as the U.S. government sought to establish control over new territories and discourage unauthorized incursions. As a result, while some filibusters continued their activities, the treaty marked a shift towards more formal U.S. expansionist policies and a decline in popular support for filibustering efforts.
