Missouri Compromise Map: Understanding the 1820 Slavery Boundary Agreement #2241982 (License: Personal Use)

This educational map illustrates the 1820 Missouri Compromise, which admitted Missouri as a slave state and Maine as a free state while prohibiting slavery north of the 36°30′ parallel in the Louisiana Purchase lands. Key territories-including Michigan, Arkansas, and unorganized western lands-are labeled, with color-coding distinguishing free (green) and slave (orange) regions. The red line marks the critical compromise boundary that temporarily eased sectional conflict.

Used in history classrooms, museum exhibits, and educational websites to explain antebellum U.S. politics; matches user intent for learning about slavery expansion, congressional compromises, or pre-Civil War geography.
