Answer: It couldn't have!

The US-Mexican War, which took place from 1846 to 1848, significantly influenced the outcome of the Texas Revolution. To understand this connection, let's break it down step by step:

1. Background of the Texas Revolution: The Texas Revolution was a conflict between Texan settlers, who sought independence from Mexico, and the Mexican government led by President Santa Anna. The Texan forces, under the leadership of figures like Sam Houston, fought to establish the independent Republic of Texas.

2. Annexation of Texas: In 1845, the United States annexed Texas and admitted it as the 28th state. This decision heightened tensions between the US and Mexico, as Mexico still considered Texas as part of its territory, and it saw the annexation as a violation of its sovereignty.

3. Triggering the US-Mexican War: As a result of the annexation, the border dispute between Mexico and the United States intensified. The two nations had conflicting views on the boundaries of Texas. The United States claimed the Rio Grande as its border, while Mexico argued that it was the Nueces River. This dispute eventually led to armed conflict, thus initiating the US-Mexican War.

4. Impact on the Texas Revolution: The US-Mexican War significantly impacted the outcome of the Texas Revolution in several ways:

a. Diversion of Mexican forces: With the outbreak of the war, Mexico had to divert a substantial portion of its military resources to defend its northern territories against the United States. This diversion weakened the Mexican government's ability to effectively address the situation in Texas and suppress the ongoing revolution.

b. Support for the Texan cause: The United States, due to its annexation of Texas, saw the Texan rebels as a natural ally against Mexico. During the war, the US provided political, diplomatic, and limited military support to the Texan revolutionaries. Though the official US involvement was limited, this support bolstered the Texan cause and indirectly aided their fight for independence.

c. Recognition of Texan sovereignty: As the US-Mexican War progressed, the United States military achieved significant victories against Mexico. This success, coupled with diplomatic negotiations, eventually led to the signing of the Treaty of Guadalupe Hidalgo in 1848, which formally ended the war. As part of this treaty, Mexico recognized the Rio Grande as the border between Texas and Mexico, thereby confirming Texan sovereignty.

In summary, the US-Mexican War influenced the outcome of the Texas Revolution by diverting Mexican military resources, providing indirect support to the Texan rebels, and eventually leading to the recognition of Texan independence through the establishment of the Texas-Mexico border.
