Map of territories in the southwestern quadrant of the United States (EUA) and México. Areas are shaded in tan, pale peach, and gray along the Rio Grande and cream white across the rest of the US.

Extended Description

A roughly rectangular tan area encompassing parts of modern-day California, Nevada, Utah, and Arizona is labeled “1848, Ceded by Mexico/México cedió.” To the east, a gray area loosely mirroring modern-day Texas, is labeled “1845, Annexed by US/EUA anexó.” A blue line representing the Rio Grande (Río Bravo) winds from about halfway down the tan area and along most of the western border of the gray area to the gulf. A sliver of lighter tan between the territory ceded in 1848 and México is labeled “1854, Gadsden Purchase from Mexico/Venta de La Mesilla a EUA.”
