1. Texas remains part of Mexico. Mexico would have maintained control of its northern territory, including Texas, and the United States would not have expanded westward as it did in the 19th century. This could have prevented the Mexican-American War and other conflicts between the two countries.
2. Texas becomes an independent country. Mexico could have granted Texas independence, similar to what happened with Central America in 1821. This would have created a buffer zone between the United States and Mexico, potentially reducing tensions between the two countries.
3. The United States annexes Texas. The United States could have annexed Texas regardless of Mexico's wishes, as it did in 1845. This would have likely led to war between the United States and Mexico, and the United States would likely have emerged victorious, acquiring even more Mexican territory in the process.
4. A different country or countries emerge in the region. It's also possible that a different country or countries could have emerged in the region, either through colonization by European powers or through internal divisions within Mexico. This could have created a complex geopolitical situation in the region, with multiple countries vying for control.
In reality, the Texas Revolution did not result in a clear victory for either side. After a series of battles and negotiations, Texas became an independent country in 1836, but Mexico did not recognize its independence until 1848. The United States annexed Texas in 1845, which led to the Mexican-American War and the eventual loss of more than half of Mexico's territory to the United States.
