Gold became highly concentrated in California, United States as the result of global forces operating over hundreds of millions of years. Volcanoes, tectonic plates and erosion all combined to concentrate billions of dollars’ worth of gold in the mountains of California.

The 49ers were the first major league professional sports franchise based in San Francisco and is the 10th oldest franchise in the NFL. The name “49ers” comes from the prospectors who arrived in Northern California in the 1849 Gold Rush. The team is legally and corporately registered as San Francisco Forty Niners.

Arriving in covered wagons, clipper ships, and on horseback, some 300,000 migrants, known as “forty-niners” (named for the year they began to arrive in California, 1849), staked claims to spots of land around the river, where they used pans to extract gold from silt deposits.

The 49ers, most of whom were men, came from the eastern United States as well as other parts of the globe, including Europe, China, Mexico and South America. By the mid-1850s, more than 300,000 people had poured into California.

Forty-niners came from Latin America, particularly from the Mexican mining districts near Sonora and Chile. Gold-seekers and merchants from Asia, primarily from China, began arriving in 1849, at first in modest numbers to Gum San (“Gold Mountain”), the name given to California in Chinese.

A border skirmish along the Rio Grande started off the fighting and was followed by a series of U.S. victories. When the dust cleared, Mexico had lost about one-third of its territory, including nearly all of present-day California, Utah, Nevada, Arizona and New Mexico.

Coastal exploration by the Spanish began in the 16th century, with further European settlement along the coast and in the inland valleys following in the 18th century. California was part of New Spain until that kingdom dissolved in 1821, becoming part of Mexico until the Mexican–American War (1846–1848), when it was …

Gold had not been discovered there yet, but Polk wanted California and its magnificent San Francisco Bay as the American gateway to trade with China and other Asian nations. Polk was worried that other nations, such as England or France, might take California if the United States did not act.

The Golden State

Conflict with Mexico began when the United States annexed Texas as a state in 1845. Mexico claimed that the new border between Texas and Mexico was the Nueces River, while the United States contested the border was the Rio Grande. Fighting began when a detachment of U.S. cavalry was attacked near the Rio Grande.

The Mexican-American war (1846-1848) changed the slavery debate. It almost doubled the size of the United States and began a debate, between Northerners and Southerners, over what to do with the newly acquired land.

The war affected the US, specifically Texas, and Mexico. For Mexico, there was loss of life, economic ruin, and huge damage to property. For the US, they gained huge new pieces of land.

(1848) ended the Mexican-American War (1846-1848) and was signed in its namesake neighborhood of Mexico City. Its most significant result was the “Mexican Cession” transferring California, Nevada, Utah, and parts of four other states to the U.S. It also made the Rio Grande the boundary between Texas and Mexico.

The treaty effectively halved the size of Mexico and doubled the territory of the United States. This territorial exchange had long-term effects on both nations. The war and treaty extended the United States to the Pacific Ocean, and provided a bounty of ports, minerals, and natural resources for a growing country.

It stemmed from the annexation of the Republic of Texas by the U.S. in 1845 and from a dispute over whether Texas ended at the Nueces River (the Mexican claim) or the Rio Grande (the U.S. claim).

The fighting was at an end. By the Treaty of Guadalupe-Hidalgo (February 2, 1848), Mexico accepted the Rio Grande as its boundary. The treaty also gave the United States Mexico’s northern provinces of California and New Mexico.

Territories obtained in the Mexican American War of 1848 caused further sectional strife over the expansion of slavery in the ante bellum period. The ideological seeds of the American Civil War, in turn, were sown during that conflict.

By its terms, Mexico ceded 55 percent of its territory, including parts of present-day Arizona, California, New Mexico, Texas, Colorado, Nevada, and Utah, to the United States. Mexico relinquished all claims to Texas, and recognized the Rio Grande as the southern boundary with the United States.

If the United States annexed all of Mexico, then certain things would change. Mexico would have a more efficient government. Mexican drug cartels would be annihilated. America doesn’t need to build a very long wall anymore, it only needs a smaller one at the Southern Mexico border.

According to Gregory Weeks, author of U.S. and Latin American Relations (Peason, 2008, p. 56), “The Teller Amendment, authored by a Colorado Senator who wanted to make sure that Cuba’s sugar would not compete with his state’s crop of beet sugar, prohibited the president annexing Cuba.”

Mexico

The Mexican–American War, also known in the United States as the Mexican War and in Mexico as the Intervención estadounidense en México (U.S. intervention in Mexico), was an armed conflict between the United States and Mexico from 1846 to 1848….Mexican–American War.

Gadsden’s Purchase provided the land necessary for a southern transcontinental railroad and attempted to resolve conflicts that lingered after the Mexican-American War. Fearing the colonists would rebel as those in Texas had, Mexican President Juan Ceballos revoked the grant, angering U.S. investors.

Trist ignored the recall order and negotiated terms that allowed the United States to buy California (north of the Baja Peninsula), as well as what amounted to half of Mexico’s territory for $15 million. On February 2, 1848, the Treaty of Guadalupe Hidalgo was signed in Mexico without President Polk’s knowledge.

Mexico had claimed a huge part of land, roughly around 5,000,000 kilometers squared.

The Treaty of Guadalupe Hidalgo, signed on February 2, 1848, ended the Mexican-American War in favor of the United States.

September 28, 1821 The territorial organization of the First Mexican Empire was the largest extension of Mexico as an independent country: 4,925,283 km2.
