Going To War With Mexico Research Paper

As stated in President James Polk’s war message of 1846, “...I had ordered an efficient military force to take a position ‘between the Nueces and the Del Norte [Rio Grande].’ This had become necessary, to meet a threatened invasion of Texas by the Mexican forces” (Document B). From the perspective of the United States, the people of Mexico were not authorized to cross the Rio Grande into American territory. However, since the Treaties of Velasco that Santa Ana signed were invalid, Texas still belonged to Mexico. Mexican troops were not “invading” Texas; they were trying to retain the land that had been stolen from them. Therefore, President Polk had no right to send American troops to Mexican territory. Some may argue that the war was justified because Mexican troops attacked American soldiers on American territory. For example, they contend that, “Mexico has passed the boundary of the United States, has invaded our territory and shed American blood upon American soil” (Document B). The United States declared war against Mexico because they believed American soldiers had been attacked by Mexican troops in American territory. However, since the annexation of Texas was illegitimate, that territory still belonged to Mexico. The American soldiers were not killed on American land; they were killed on Mexican land. Thus, America’s reasoning for declaring war was inaccurate, and the Mexican-American war was

Texas and the United States believed that the proper borderline between Texas and Mexico was the Rio Grande, but for Mexico it believed that the border between them and Texas is the Nueces River.”(Hook) As you can see the United States and Mexico had different beliefs. This evidence shows the US was justified in going to war with Mexico because the US believed that Mexico had a smaller amount of land they what they think they have. But Mexico believes that it has more land. Mexico and the United States were fighting over the disputed territory which was between the Nueces River and the Rio Grande, which made the tension between Mexico and the US more negative. “ on April 24th of April a party…..of sixty three men and officers, were… dispatched from the American camp up the Rio del Norte.(Doc B)” This evidence shows that Mexico had went against its boundary and fought with American men in the striped area where Mexico and the United states were already fighting for. This Made thing more difficult to handle because the Us and Mexico were already fighting for land and the probably made things worse between the two

The war between the United States and Mexico was the first foreign battle the US had fought in as a nation. It was also the first war fought on enemy land. In 1836 Texas won its independence from Mexico. Three times, the US wanted annexation for Mexico and three times it was denied due to the impression of slavery. In 1845 Texas was claimed as a state and because of that Mexico broke all diplomatic relations with the United States. The Mexican-American War was fought between the United States and Mexico between April 1846 and February 1848. The US claimed that the dispute started over the annexation of Texas and other territories they wanted. However, it was also claimed that the US went to war to spread slavery not for the expansion of land,

Polk had said that Mexico were planning on an invasion and declared war on Mexico. This didn’t show that we show not be afraid or fear military ambition. It showed how selfish man can be just to gain more territory because they believed that it was their right to expand the country. Mexico only wanted what was theirs after claiming independence from Spain, and not have it taken away. Texas was under Mexico law, and Mexico banned slavery. Many Americans settlers did live in Texas at the time and knew it was against Mexico’s law but still had slaves anyways. The war lasted for three years, but soon Mexico decided to sign a peace treaty that gave territories to America. America paid Mexico 15 billion for lands that are known today as California, Arizona, Colorado, Nevada, New Mexico, Utah and

“At this period, citizens of the United States had already begun to into Texas... That deal was... That this extensive prevent to become a part of the United States…” (Doc D ,Charles Sumner This evidence Demonstrate that America was not justified in going to war with Mexico because all they wanted to do was to get their lands. “A current of emigration soon followed from the United States favorite. Slaveholders cross the Sabine with their slaves, In defiance of the Mexican ordinance of freedom” Doc D,Charles Sumner. This mean that America was All About Us Us expanding slavery into stole a land and was not justified into going in with

With the widespread confusion and battles throughout the Nueces River and the Rio Grande, the U.S had offered a treaty to Texas, and shown in Document C “It would consider such an act ‘A declaration of War.’” Today Texans and American citizens believe that Mexico had attacked first, when in reality they were just defending their land. The U.S took Mexico’s land and had blamed them for attacking for the start of several battles and casualties when Mexico didn’t give up the land in the first place. Explained in Document D “Citizens of the United States had already begun to move

America was justified in going to war as Mexico invaded the country,American troops were killed by the Mexicans,and Mexico decided to strike first.When Texas declared its independence from Mexico in 1836 and stated that the Rio Grande was the border boundary.However in 1846,Mexican forces decided to cross the border line as it was known as an invasion against the US.On Document B President Polk stated, “The Congress of Texas,by its act of December 19,1836, had declared the Rio del Norte to be the boundary of that Republic.”(Doc B)On April 24th,1846,an American force of 70 men were dispatched to camp north of the Rio Grande. However,a larger Mexican force,decided to attack the American force where 16 American soldiers were killed.On Document

As Texans began demanding freedom, they deciding to away from Mexico, causing tensions between the United States and Mexico. In 1845, tensions began to lead to threats between the two countries when the United States decided to annex Texas into their country and ultimately led to the Mexican-American war. The U.S. was not justified in going to war with Mexico. A reason is that James K. Polk, president at the time, decided to send American soldiers onto disputed territory which Mexico thought was theirs. Doc C is an article written by Jesus Velasco-Marquez discussing the Mexicans viewpoint on the war with the United States in 1846. According to Doc C,¨In the eyes of the Mexican government, the mobilization of the US army was an outright attack

“The Congress of Texas, by its act of December 19, 1836, has declared the Rio del Norte to be the boundary of that republic…” ~President James Polk. The Congress of Texas declared the Rio Grande the boundary.” (Doc B Paragraph 2-3) When this happened the Americans did not listen to the boundary and crossed it. There were two major problems with this. The first problem with this was that the Americans were bringing slaves into this slave free dominion. The second major complication was that the Americans were crossing the boundaries and claiming land that was the Mexicans. This evidence shows the US was not justified in going to war with Mexico because the Americans were stealing Mexican land. They were also crossing the boundaries, and stealing the land right after Mexico declared they were a slave free dominion. “Certainly Mexico...might justly charge our citizens with disgraceful robbery, while, in seeking extension of slavery.”~Charles Sumner. (Doc D Paragraph

In 1846 throughout 1848, a war to conquer land from Mexico were orders held by James K. Polk. An unjust war is about to occur, In 1846 Texas becomes Independent from Mexico and the United States. To begin with, Mexico approves for the Americans to settle onto Texas with one condition to not bring slaves along with them. During this time period, slavery was one of the most important political concerns and they opposed slavery. The Americans didn’t hold the values of anti-slavery, during this time they valued Manifest Density strongly. Accepting some restrictions from Mexico placed was nothing compared to its own destiny to occur from preventing America to stretch outward towards the Pacific Ocean. The main conflict started with the annexation of Texas, a dispute on the nation’s border, the Mexicans consider the Nueces river to be the border of Texas as for Americans that wasn’t enough land so they consider, Rio Grande the border. A way to aim to

During the 1800s the phrase “Manifest Destiny,” meaning obvious fate, was the belief that it was America’s right and duty to spread across the North American continent. This was a cause for Americans to start expanding their land ownership throughout the continent by settling in areas which they knew had many valuable resources. During the time that America had decided to annex Texas, many problems started to rise between Mexico and the United States. In the eyes of Mexico, the annexation of Texas was an act of war. Furthermore, both countries were having a hard time trying to agree on a border, because both wanted control of the Rio Grande, but it was unfortunate that only one of them would be able to claim the river. So, in 1846, Mexican soldiers started firing at American troops who were patrolling along the Rio Grande, which lead to sixteen Americans being killed and wounded. Polk used this as a cause for war, and stated that Mexico, “has invaded our territory and shed American blood on American soil.” All in all, the United states was clearly justified in going to war with Mexico, because Mexico had invaded American territory, shed American blood upon American soil, had come within American power, and the United states was able to offer them a position above any that they have previously occupied.

In 1845 Texas was annexed as a state, however disputes between America and Mexico remained concerning where the border would be located. President Polk at the time had no choice but to send troops due south to defend Texas and the Thornton affair, won by the Mexicans, would force congress to declare war on Mexico.

The land didn’t even belong to the United States. This is supported by documents C and D. Mexico allowed the people of the United States to expand to the west into what is now the southwest part of the United States. The United States had no right to annex Texas. “The annexation of Texas into the United States would be considered “a declaration of war” (C). American settlers in California believed the land was theirs because Mexico had no control of it. The United States took the land away from Mexico by moving into their territory and calling it their own.

The US was provoking Mexico. The president played a big role in annexing Texas, he set up troops to defend against Mexico taking back Texas. John O’Sullivan also told Mexico that they were going to take California after taking Texas. Polk supported and played a big role in Texas being annexed. (Doc.A) The US needed his approval mainly to make Texas part of the US. The government voted that Texas should be annexed but without the President saying yes it would have taken a lot longer then it did to make Texas a part of the US. The President set up troops to fight with the Mexicans increasing the level of the situation also. Document B says the President set up troops between the Nueces and the Rio Del Norte. He did this because he felt that Mexico

*The type of source I am using is from the technology institute of Mexico. Jesus Veiasco Marquez was the creator of this and it is about the Mexican viewpoint on the war with the United States. *From the issue 41 of voices in Mexico it states, “ ...the annexation of Texas to the United States was inadmissible for both legal and security reasons.” In paragraph three of this issue, it also states,” ... the US army was an outright attack on Mexico…
