The map depicts the United States as it stood in 1830, with 24 states (orange), organized territories (light blue), unorganized territories (green), claimed but disputed areas (pale green), and foreign-controlled regions such as Mexico (southwest) and the joint U.S.-British Oregon Country (Pacific Northwest). Key milestones include Missouri’s admission in 1821, Arkansas Territory established in 1828, and Florida Territory acquired via the Adams-Onís Treaty in 1822. The Mississippi River serves as a central geographic and political boundary during westward expansion.
