Mexican-American War Dbq

As Americans, we’ve taken far greater than just tacos, burritos, and nachos from the culture of Mexico. Through America’s past relations with Mexico, America has taken large amounts of land, and a sense of power from country south of the United States, Mexico. In 1846, James Polk, a former president of the United States, declared war on Mexico. There was confusion between Mexico and America. Land was being traded, new borders were being formed, but disorientation was aroused causing conflict. Differences in culture, beliefs, and even national law led to dispute among these two countries, making it even more difficult to reach a treaty of peace, or a deal. The Mexican-American War was not justified because it was an excuse for gaining land,

John Sullivan founded the manifest destiny movement (Doc A). This idea of God leading the U.S. westward into new territory spread, reaching the president, James K. Polk. He liked this idea, for he wanted to gain more land, especially from Mexico. James Polk was greedy for more territory, as he was a Democrat, who supported annexing Texas and Oregon. Using manifest destiny to obtain this land for the U.S. meant more Americans would support the westward expansion. Therefore, Polk was able to send Americans, particularly farmers, westward, which would soon cause great conflict with Mexico, leading to war. Polk sent multiple representatives to Mexico, wanting to make deals for land in Mexico’s possession (Doc E). One specific person Polk sent was WIlliam Emory. He went to offer a friendship with Mexico and to state reasoning for the U.S. invading Mexican territory. James Polk knew the Mexican Republic was angry at America for invading Texas. So, logically, he sent one of many “ambassadors” to create a peace treaty, and offer a friendship supplying benefits, such as protection for Mexico. Although, Mexico declared the U.S. as “invaders” and rejected the proposed treaties. Though it may seem former president James Polk was pro-manifest destiny, and genuinely wanted a national agreement of peace with Mexico, he was really eyeing their land, where he could obtain the territory, and

These two countries had reached a deal of new boundaries between themselves. Although, Mexico believed the Nueces River was the newly formed border, while America thought the Rio Grande serves as the new border. President James Polk sent a total of sixty three troops to station along the northern banks of the Rio Grande. Now, the Rio Grande was south of the Nueces River. Because the Mexicans believed the Nueces, which was farther north, was the new border, it led them to believe the Americans had “invaded” Mexico, causing confusion, and bloodshed, eventually leading to a declaration of war from the U.S. government. The Mexicans had crossed what America thought was the border, the Rio Grande. James Polk issued a declaration of war with Mexico after hearing his troops were being killed, due to a “Mexican invasion” (Doc G). While James Polk believed Mexico had invaded Texas, now a part of the Union, the Mexican Republic believed American troops were at fault for invading Mexico. Rumors spread throughout both countries of the other invading. The Mexicans had formerly offered peace, yet none was reached, continuing on to the war. Confusion of new borderlines and “invasions” of troops spread causing more conflict between America and Mexico, which was one of the major causes of the Mexican War. Once again, the Mexican War was not justified because it was an excuse for gaining land, it was meant
