Mexican American War 1846

Why did the war take place?

The war took place over the issue of Texas. In the 1830s, American settlers in Texas fought against Mexican rule and declared independence from Mexico. Mexico was defeated and continued to claim its right over Texas. So when U.S. Congress agreed to make Texas the 28th state of U.S.A., Mexicans were angry.

Another major reason was the disagreement over the border of Texas. The Mexican government said that the Texan border ended at Nueces River. The Texans claimed that their border went all the way until the Rio Grande River. It was finally to settle this border dispute that both sides came to war.

The Mexican American War was also known to Americans as the Mexican War, it was caused by the United States forces annexation of Texas in the year 1845.

The Mexican government claimed that the territories of Texas ended at the Nueces River, but the Americans claimed that the territory ended at the Rio Grande.

These differences of opinion caused a war which was basically a territorial dispute.

The American forces would eventually acquire more than 500,000 square miles of what time was considered Mexican territory.

 

Beginning of the Mexican American War

The Mexican American War began on April 25, 1846. American government sent an army under General Zachary Taylor to reach the Texan border and stop any Mexican army from crossing the Rio Grande River.

Mexico responded by sending its own army which crossed the Rio Grande River and attacked the American fortifications.

This led to the battles of Palo Alto and Resaca de la Palma, both of them the earliest proper battles in the war.

The Mexican army was defeated in both wars and was forced to retreat beyond the Rio Grande River, back into the Mexican territory.

American forces enter Mexico

After defeating the Mexican army on this side of the border, the American army crossed the Rio Grande River and entered Mexico. Its purpose was to force the Mexican government to accept the Texan independence and to agree the Rio Grande River as the official border.

The Mexican government, on the other hand, braced for a defensive war and said that the American forces were encroaching on Mexican territories. So the Mexican American war continued, now taking place inside Mexico.

A number of battles were fought and the Mexican army lost most of them, eventually also losing control of many important cities. These include Monterrey and the capital of Mexico, the Mexico City.

Negotiations for Peace

After losing most of the battles during the Mexican American war and finally losing control of the Mexico City in 1847, Mexico realized that it could not possibly win the war. The American government also wanted to end this military conflict which had gone on for long enough.

So both sides decided to negotiate for peace. These negotiations finally resulted in peace treaty signed by both sides in February, 1848. This was called the Treaty of Guadalupe Hidalgo. The treaty was ratified in May 1848, effectively bringing the war to an end.

Aftermath

Mexico was forced to recognize the Rio Grande River as the official border between U.S.A and Mexico. Mexico also gave up a huge portion of its northern territories which include modern-day states of New Mexico, Utah, California, Arizona and Colorado as well as parts of Wyoming and Kansas.

In return, U.S. government paid $15 million for the acquisition of these territories. Following the conclusion of peace, the American army returned to the U.S. territories, handing back the control of the conquered land to the Mexican government.
