The Claim That America ‘Stole’ California From Mexico Is An Ignorant Lie

A brief study in California history reveals the real population of the Golden State.

Recently, Katy Perry claimed on her Instagram page that California has always belonged to Mexico and is another example of U.S. racism and bigotry.

That’s not quite … right. California, like most of the world, has a history that’s slightly more complex than will fit an average bumper sticker.

Prior to the Spanish arrival in 1542, there were more than 100 different tribes inhabiting modern-day California. Most were small, and the total population of the area is estimated to be approximately 300,000.

Although there were some minor explorations and small settlements, Spain left California largely unexplored and unsettled for nearly the next 200 years. This was due to a combination of factors such as distance from Spain, the strained Spanish finances, and also because there were no pack animals, little agricultural tradition, and a food supply that was less than appealing to Spanish palates.

By the late 18th century, however, the Spanish decided they needed to better organize their North American territories to preempt incursions from other European powers, particularly the French and Russians. As a result, Spain began a more robust exploration of the state and would slowly colonize it, setting up missions along the vast coastal areas.

By the early part of the 19th century, however, Spain’s fortunes were changing, the empire was stretched too thin, and after a decade of fighting, Mexico gained its independence in 1821. The new nation included what is today Mexico, as well as California and much of the American Southwest, stretching east to Texas and north to Colorado. Here’s where the rub in the argument that the United States stole California begins.

The population of California in 1800 was approximately 300,000 — almost all natives — essentially the same as it had been for centuries. By 1848, however, it had dropped to half of that due to disease, which was responsible for 60-80 percent of the decline, and the Spanish working to death or killing the natives.

California, at the time of Mexico’s independence, was sparsely populated, with just 200,000 people, and that number was rapidly shrinking. For perspective, that’s 0.5 percent of today’s 40 million inhabitants. Add to that the fact that Mexico could barely be called a functioning country, as in the 27 years from 1821 to 1848, it had literally 40 heads of government. As would seem obvious, the governments were dysfunctional, had an incredibly large land mass to govern, little tax revenue coming in, and very limited finances with which to field an army to secure it, never mind to carry out the minimum responsibilities of a government.

To better understand how dysfunctional and empty Mexico was, consider Texas. In 1835, Texas had a population of less than 45,000 people, 30,000 of whom were Anglo settlers who’d been given permission to settle the lands by the Mexican government. The remainder included approximately 7,000 Mexicans and 5,000 black slaves. Because of conflict with the Mexican government on issues from slavery to religion, in October of that year, Texas started a war for independence. By March 1836, it had declared itself the Republic of Texas. That could never have happened had Mexico been able to populate the area on its own or keep it from breaking away. But it couldn’t, so Texas was born.

The American annexation of Texas, a decade later in 1845, was the catalyst that brought California into the United States. When the U.S. annexed Texas, Mexico disputed exactly where the southern border was. The Americans said it was the Rio Grande while the Mexicans said it was the more northern Nueces River. After negotiations failed to reach an agreement, American troops marched to the Rio Grande to bolster the American claim. The Mexicans, seeing this as an encroachment on their land, attacked the American troops, and the United States then declared war.
