What if Mexico Kept California?

On 2 February 1848 Mexico signed away roughly half its territory. California, Nevada, Utah and most of Arizona and New Mexico went to the United States for fifteen million dollars. Gold had been found at Sutter's Mill nine days earlier, and nobody at the negotiating table knew it yet. This video asks what North America looks like if the war goes the other way. The Mexican-American War began in 1846 over the border of a state Mexico had already lost. Twelve years after Texas broke away, the two governments could not agree whether that border ran along the Nueces or the Rio Grande, and the dispute became the pretext for a campaign that ended with an American army in Mexico City. A Mexican victory does not simply redraw a line. It removes the gold rush as an American event, which means no hundred thousand migrants crossing the continent in 1849, no San Francisco as a boom port, and no Pacific coastline for the United States at all. It also changes the argument that tore the country apart over the following decade, because the question of whether the new territories would permit slavery is what broke the compromises of the 1850s. On the other side it hands Mexico a coastline it had never been able to settle. Alta California held only a few thousand non-indigenous inhabitants in 1846, its garrisons were minimal, and Mexico City had lost effective control of its far north long before the war. Holding that ground against a growing neighbour is a different problem from winning a battle. Covered in this video: the state of Mexican California before the war, the border dispute and the declaration of war, the campaigns of 1846 and 1847, the Bear Flag revolt, the treaty and what it transferred, the timing of the gold discovery, and a step by step alternate timeline running through the 1850s and beyond. #alternatehistory #whatif #mexicanamericanwar #california #history
