What better way to describe Mexico’s territorial evolution as a nation than via an animated graphic? Fortunately, we didn’t have to do the work ourselves, but found one, showing all of North America, at giphy.com. Sadly, it is no longer active.
The graphic covered the period 1750-2000. Mexico appeared in 1821, when it became formally independent from Spain. The Mexico of 1821 was much larger than today’s Mexico. Its northern border in the 1820s and 1830s reached deep into the modern-day U.S. states of Texas, New Mexico, Arizona, California, Utah and Colorado. These areas remained part of Mexico until after the disastrous 1846-48 Mexico-U.S. war.
At the end of the Mexican-American War (1846-1848) the 1848 Treaty of Guadalupe Hidalgo ceded over half of Mexico’s territory to the USA. A few years later, under the 1853 Gadsden Purchase (Treaty of La Mesilla), northern portions of Sonora and Chihuahua were transferred to the USA. With minor exceptions since, to take account of changes in the meanders of the Río Bravo/Río Grande, this established the current border between the two countries.
