"Manifest Destiny was a slogan popular in the 1840s. It was used by people who claimed it was God's will for the U.S. to expand all the way to the Pacific Ocean. These people did not include many Mexicans."The year is 1846. The Southern United States' plantation economy is becoming less and less practical as Europe gets more of its cotton from other sources, particularly India and to a lesser extent Egypt. Industry is driving more and more people north, and the balance between free and slave states is rapidly shifting. This only increases when the Oregon Territory is annexed. The answer: build a railroad from New Orleans to the Pacific coast, where many American expatriates already live. But the land in between is in the hands of a hostile Mexican government... Meanwhile, European powers are developing spheres of influence in China, and the US government finds itself in need of a large Pacific port, and there's a big one in the Mexican province of Alta California, which everyone knows is much more valuable than the newly-annexed Texas. Unfortunately, relations with the British Empire are tense and there's a great fear that this will be their next conquest. Lasting from 1846-1848, the Mexican American War was fought between the United States and Mexico over a small land dispute in Texas. Despite its small origins, it eventually resulted in the invasion of Mexico. Though the war is seldom depicted in contemporary media, both the United States and Mexico as we know them exist, in part, as a result of this war.

Depictions in fiction
- In the Dear America series, Valley of the Moon, is the diary of Maria Rosalia de Milagros, who lives in Alta California in 1847. The novel primarily deals with Maria's personal life, but it also has bits about the early parts of the war when California briefly becomes a country.
- It must count for something that Zorro lives in California in the era before this war, i.e. California when it was under Spanish/Mexican rule. The Mask of Zorro is actually set on the eve of the Mexican-American War, while its sequel, The Legend of Zorro, picks up shortly after the war and is set on the backdrop of California becoming a state.
- Similar to the Zorro example, The Lone Ranger takes place in the brief interlude of Texas statehood prior to the war.
- In one of Sound Horizon's songs, "A Beautiful Starry Night," the protagonist's winding path at one point leads him right into the Mexican American War in 1846, where his knee is shattered from a musket wound.
- The 1999 Tom Berenger film One Man's Hero is about the Saint Patrick's Battalion.
