The Mexican American War began on April 25, 1846. The war lasted two years losing many men on both sides. The Mexican war was the third major fought by the United States. In 1810, Miguel Hidalgo y Costilla triggers the beginning of Mexico’s fight for independence from Spain. Mexico gained its independence in 1821 after a long and bloody revolution against Spain. For Mexico, the war between them and the United States was a fight to keep their institutions and national integrity intact, to protect themselves from present and future aggressions by the Americans, but more than anything else, the war was a struggle for land. In the early days of the republic, most Americans made their living by farming, so in 1803 President Thomas Jefferson purchased the Louisiana Purchase Territory because he wanted to provide “room enough for out descendants to the thousandth and ten thousandth generation.” In 1803 the United States purchased land from Napoleon west of the Mississippi, also known as the Louisiana Purchase. The Unites States nearly doubled in size, extending its borders two thirds of the way from the Atlantic Ocean to the Pacific Ocean. In 1804-1806 the Lewis and Clark expedition explores western North America. Mexico had a population of only about 2,500 living in Texas, they offered cheap land to attract Americans and build up the territory. Mexico only allowed one religion which was Catholicism and for everyone to follow the teachings of the church. The U.S government marked the route of the Santa Fe Trail so settlers in New Mexico can get goods from the U.S that they have not been able to get from Mexico. By the early 1800s many of the inhabitants of Mexico didn’t like the Spanish Rule and wanted to establish a democratic government. In 1810 there were several executions. The gachupines (those born in Spain) executed Miguel Hidalgo y Costilla who had led a large group of mestizos (the offspring of mixed marriages) who were rebels in stopping the gachupines from gaining more power. September 16 is celebrated as Mexico’s Independence Day, even though they didn’t achieve independence. It was celebrated on that day for when Hidalgo got executed for trying to rebel from the gachupines who were the ones with power and he became a popular folk hero and inspired many Mexicans to continue to fight for their freedom. In 1813 and 1814 Jose Maria Morelos y Pavon was also put into death for also trying to bring down the gachupines, it wasn’t until 1821 when Mexico got its independence. One of the reasons why there was even a war was because the U.S tried to annex Texas. President Anson Jones had accused the U.S of trying to “annex a war”. Mexico called the Americans Yankees because they were Anglo-Americans and they weren’t from Mexico. The other reason they went into war was because of the manifest destiny. The Americans wanted to take over the Spanish possession. Texas had gone through a lot since they were like in the middle, the reason Mexico and the United States got into the war. Texas also had to fight for their independence. Texas, Mexico, and the United States had lost men in all the battles and plus the war between the United States and Mexico.
The Rio Grande is fifth longest river of North America. At the end of May, President James K. Polk asked General Zachary Taylor to take troops from New Orleans to Texas to protect against Mexican “Invasion.” On June 11, 1845, he ordered General Taylor to take a shipload and move them “on or near the Rio Grande.” Taylor gathered his men 25 miles from the spot where the Rio Grande empties to the Gulf of Mexico. By October of 1845, 4,000 troops waited in Corpus Christi which was the last North American settlement in Texas. The Rio Grande was the boundary between Mexico and the United States. If the Nueces River was the boundary, a blockade was definitely a hostile act against Mexico. His army consisted of one regiment of dragoons (heavily armed...
