One of the causes of the war between the United States and Mexico was Mexico's resentment towards the annexation of Texas by the United States.

One of the causes of the war between the United States and Mexico was that Mexico resented the annexation of Texas by the United States. To understand this cause, we can examine the historical context of the time.

In the early 19th century, Mexico gained independence from Spain and established itself as a republic. However, Mexico was facing internal instability and struggled to maintain control over its vast frontier territories, including Texas. In 1836, Texas, then a Mexican province, declared independence and formed the Republic of Texas.

Soon after, Texas applied to join the United States, which caused tensions between Mexico and the United States. Mexico considered the annexation of Texas as a violation of its sovereignty and saw it as an act of aggression by the United States. Mexico refused to recognize Texas as an independent nation and insisted it was still a part of Mexican territory.

The United States, on the other hand, supported the annexation of Texas due to various reasons, including the desire to expand its territory and fulfill its "Manifest Destiny," a belief that the United States was destined to stretch from coast to coast.

As a result of these conflicting viewpoints, diplomatic relations between Mexico and the United States deteriorated over time. This eventually led to the outbreak of the Mexican-American War in 1846, when U.S. forces crossed into Mexican territory, sparking hostilities.

In summary, one of the causes of the war between the United States and Mexico was Mexico's resentment over the annexation of Texas by the United States. This illustrates the complexities of historical events and the role they play in shaping conflicts between nations.
