Missouri Compromise of 1820 Map - U.S. Expansion and Slavery Boundaries #2241993 (License: Personal Use)

The map depicts the political geography of the United States following the Missouri Compromise, with free states shaded solid, slave states in cross-hatch, and territories categorized by status-some closed to slavery (e.g., Missouri Compromise Line), others open. Key regions like the Unorganized Territory, Arkansas Territory, and Missouri’s admission as a slave state are clearly labeled, alongside neighboring entities such as New Spain and Oregon Country. A legend clarifies symbology, and a compass rose and scale bar aid spatial interpretation.

Used in educational history websites, digital textbooks, and museum exhibits to explain antebellum U.S. politics, territorial expansion, and the roots of sectional conflict leading to the Civil War; targets students, educators, and history enthusiasts seeking visual context for legislative compromises on slavery.
