What treaty helped the US to acquire Texas?

Answer 1

The treaty that facilitated the U.S. acquisition of Texas was the Treaty of Guadalupe Hidalgo, signed in 1848. This treaty ended the Mexican-American War and resulted in Mexico ceding a vast portion of its northern territories to the United States, including Texas, which had already declared independence in 1836. The U.S. formally annexed Texas in 1845, which was a contentious issue that contributed to the war. Thus, while Texas was not directly acquired through this treaty, the treaty solidified U.S. claims to the region following its annexation.
