Mexican-American War Dbq
Yes, United States was justified in going to war with Mexico. The Mexican-American War was fought mostly because of Texas's border confusion.

    While most Americans call the war the, “American-Mexican War”, the other side would call it, “The U.S. Invasion”. If it is God’s reasoning to expand the U.S. territory as far as possible, then is it also his reasoning to murder those upon their own land? It is not only unjustified to take the land from the Mexicans, however to become inhuman enough to kill those while doing so is unspeakable. There was no need for any more conflict at that time, so to start a war was not ideal for anyone. Would a war be more beneficial or cost efficient than a compromise or a buyout? The Mexicans had only simple ideas of allowing outsiders into their land to increase population. In the words of General Francisco Mejia, “The right of conquest has always been…

    The United States was unjustified when going to war with Mexico for multiple reasons. One of the biggest reasons was the expansion of a slavery state. Texas is very large and great for growing cotton, so if the U.S. annexed Texas, a very large slave state would be added. The second reason was that James Polk provoked the war. He was also a big believer in Manifest Destiny. This meant that he wanted to expand the land of the U.S. , and His motto was “54 40 or fight” which meant expanding the U.S. up to the northern boundary of the Oregon territory. If this goal was not achieved, they would go to war to get it.…

    The Mexican American war started in 1846, ten years after Texas won its independence from Mexico. In 1844 Texas was annexed, upon their request, to the United States. This caused trouble with the Mexican government because they believed that the southern border of Texas was along the Del Norte river, while the American government believed that the border was the Rio Grande river. When U.S. President James Polk sent troops into this disputed territory, Mexico attacked, killing sixteen American soldiers, and starting the Mexican-American war. The United States was justified in going to war with Mexico because, Texas was independent from Mexico, Mexico engaged in violence first, and Mexico was not governing Texas well.…

    Neighbors are never going to always fully get along and agree with each other. The United States and Mexico are neighbors when it came to where their land is located and they had their fair share of issues. Mexico and the United States shared a border which meant there was going to be problems between them. The United States had finally declared war on Mexico in 1846 from a buildup of different issues. There were many factors that impacted the United State’s decision to declare war on Mexico. These decisions included the idea of Manifest Destiny, the Rio Grande boundary dispute, and Slidell’s mission. All of these things were very important when it came to declaring war on Mexico or not, but they helped put the United States over the edge.…

    Texan independence and Santa Anna's actions are key reasons for the cause of the Mexican-American War. Texans and Americans knew that the Mexican government did not have the power to stop Texas from becoming independent. Rather than letting Mexican and Texan officials talk everything out they forced the captured leader to sign a document without the consent of the Mexican people. This action was undemocratic and hypocritical of Texas and the United States. Yes, Texas was justified running its own local government because Mexico just didn't have the power to govern Texas. However, they could have made better and more fair choices that could have benefitted both parties rather than benefitting only one and making the other suffer. Mexico refused to pay $2 million in damages from the Texas's war for Independence. They didn't want to pay because they never agreed to the treaty, to begin with, and…

Half of what used to be Mexico's land is now America's most valuable land. However the process of getting it was completely inappropriate and beyond unjust. The disrespectful actions taken by American settlers once they moved to Mexico, The beliefs of manifest destiny and feeling of superiority, and pure motivation to expand slavery are all reasons that America had no right in declaring war. Nevertheless, the clash between the two countries was wrong in itself.…

    The Mexican American War was a conflict between the United States and Mexico. This was a battle for land where Mexico was fighting to keep what they thought was their property and the U.S. desired to retain the disputed land of Texas and obtain more of Mexico’s northern lands. There were two main causes of the Mexican War. First, the idea of “Manifest destiny” meaning the belief that America had a God-given right to occupy and civilize the whole continent. As large number of Americans migrated towards the west searching for land, the fact that most of those areas already had people living in them was ignored. Instead, an attitude and belief that democratic Americans would do a better job of running the lands than the Native Americans prevailed. President Polk shared and led the vision of Manifest Destiny, and did offer to buy the southwest land from Mexico. However, the Mexican government refused the offer, and because of this tensions continued to rise. The second major cause of the Mexican War actually started off with the Texas War of independence .During the 1830s, Mexico needed settlers in the under populated northern parts of the country and therefore allowed U.S. citizens to come and live in the Texas area as long as they took an oath of allegiance to Mexico and converted to Catholicism. Thousands of Americans accepted the invitation and migrated to the Mexican province of Texas. Texas was annexed by the United States in 1845. Mexico claimed the international border to be the Nuecos River, while the U.S. claimed the border to be at the Rio Grande. The Nuecos River runs roughly parallel to the Rio Grande about fifty to one-hundred miles northeast (the Texas side) of it. Therefore, by claiming their respective river boundaries, both countries were trying to expand their territory. When the Mexican army crossed the Rio Grande and skirmished with U.S. soldiers, President Polk declared that America had been invaded and American blood had been shed. These words…

    The causes given for the Spanish-American war are completely irrelevant, and do not justify imperialism at all. For instance, Spain was accused of causing an explosion aboard an American battleship called the U.S.S. Maine. Several investigations at the time were conducted, showing the explosion was most likely caused by a fire on the ship (Unger 233). The excuse for entering the war was the rebellion by the Cubans against Spanish rule and the explosion of the U.S.S. Maine. Additionally, when Congress passed the Fifty Million Dollar bill, which granted the president 50 million dollars to prepare for a war before it was declared, it made more and more people become proponents of a war with Spain. The Spanish colonies gained independence in the early 1800s, but both Cuba and Puerto Rico remained Spanish territory. Many Americans sympathized with Cuba, after seeing their plight for independence. Furthermore, Americans collectively owned nearly 50 million dollars worth of real estate and industry in Cuba. William McKinley became President of the United States in 1897, and later that year the Spanish Prime Minister, Admiral Luis Carrero Blanco, was assassinated (Golay 2). People saw these as reasons for America to become involved in the war. The Spanish-American war lasted only nine weeks, and was considered a "splendid little war." However, it led to 379 battle deaths and 5,000 American servicemen dying of disease (Hastedt 2). The Spanish-American war was a tragedy marked by a superfluous fight between two warring nations. Furthermore, President McKinley was not in favor of the war, going as far to say that "War should never be entered on until every agency of peace has failed; peace is preferable to war in almost every contingency" (Golay 3). Evidently, McKinley was not…

    The idea of Manifest Destiny became extremely popular during the 1840’s to justify US intrusion into other lands. Anglos believed it was their God-given right to expand and populate other areas. With this mentality, Anglos set out to take what belonged to Mexico. American intrusion into Mexican land created conflict between the two, leading to the Mexican-American War from 1846-1848. Mexicans living in present-day California, Nevada, New Mexico, Texas, Arizona, Utah and Colorado, which became part of the United States after the Mexican-American War, experienced a drastic change in their lives. Many false promises were made with the signing of the Treaty of Guadalupe Hidalgo officially ended the Mexican-American War. Mexicans became an underrepresented…

    Many Americans don’t believe that the war was the Americans fault but the Mexicans view this war as the Invasion of the U.S. Their main reason was the dispute over the territory Texas. When the United States finally decided to annex Texas into their territory, the Mexican government though that doing this sort of thing was illegal. Mexico believed that the United States had broken the boarder treaty of 1828, which stated clearly that Mexico still had sovereignty over that territory. Not only was it a violation of the treaty but it was also a violation of the principles of the international law. When the United States decided to do this, Mexico didn’t know which laws they were going to break next and when they were going to stop which made Mexico feel threatened. Mexico felt like they should defend themselves and finally they decided to try to do this peacefully. They sent a representative to the Capitol of the United States to figure out this dispute in the most peaceful and quiet way possible. Even with the efforts to settle this, America not only refused to cooperate, but they also demanded that they receive control of the New Mexico and California territories. They finally decided to pass a decree that didn’t declare war on America but instead one that would allow them to defend against the expansion and invasion of the United…

    A further reason the Iraq war is justified is the September 11, 2001 attack on the U.S. The Bush administration made it very clear that it would act unilaterally and preemptively if its security was threaten. September 11 was the perfect opportunity for the U.S. to knock Hussein off his throne. The failure to remove Saddam would mean that, despite the terrorist attack, we as a nation were unwilling to shoulder the responsibilities of world leadership, even to protect ourselves. (Security…

    government declaring war on Mexico was simply due to the desire for more land and wealth. It’s important to understand that the true intentions of the war on the American side was not those of defense against a dangerous enemy, nor was it to spread Manifest Destiny. It was due to greed, and the longing for something that someone else had. The Mexican-American war had been a huge historical event, and still affects us today. The conflict has corrupted the relationship between the two countries, and the withering relationship is only getting weaker. The U.S. had believed that there was not land enough, and that they had needed to take over more land, aggravating other countries until there was no choice for Mexico but to fire. The United States used this to their advantage, President Polk saying that “...Mexico has passed the boundary of the United States, has invaded our territory and shed American blood upon the American soil. She has proclaimed that hostilities have commenced, and that the two nations are now at war.” He was able to convince the U.S. government to declare war on Mexico. It is important for us to understand that the strain in our relationship was not unstemmed, in fact there is many components that lead to this strain. This connects to the current “illegal immigrants” issue, whereas America has responded by saying that we must build a wall to separate the two countries. We have to learn to learn from our mistakes and try to mend the relationship, instead of blaming one…
