Why did Andrew Jackson lead American troops into spanish Florida?

Andrew Jackson led American troops into Spanish Florida in 1818 primarily to pursue runaway slaves and combat the Seminole Indians, who were harboring them. He aimed to quell the increasing raids across the border and assert U.S. authority in the region. His actions ultimately contributed to the U.S. acquiring Florida through the Adams-Onís Treaty in 1819, solidifying American control over the territory. Jackson's military campaign was controversial but reflected the expansionist desires of the U.S. at the time.
