““Jackson began raids into Florida, arguing it was a sanctuary for escaped slaves and for marauding Indians. Florida, he said, was essential to the defense of the United States. It was that classic modern preface to a war of conquest. Thus began the Seminole War of 1818, leading to the American acquisition of Florida. It appears on classroom maps politely as “Florida Purchase, 1819”—but it came from Andrew Jackson’s military campaign across the Florida border, burning Seminole villages, seizing Spanish forts, until Spain was “persuaded” to sell. He acted, he said, by the “immutable laws of self-defense.””
