Missouri Compromise Map (1820) - Slavery Division & U.S. Territorial Expansion #2242014 (License: Personal Use)

The map depicts the United States in 1820 following the Missouri Compromise, highlighting newly admitted states like Missouri (slave) and Maine (free), alongside unorganized territories and the critical 36°30′ latitude line that prohibited slavery north of it (except Missouri). Color coding distinguishes free states/territories (yellow), slave states/territories (green), areas closed to slavery by the compromise (pink), and those open to slavery (purple). Key dates of statehood and territorial organization are annotated for historical context.
