How did the demographic makeup of Texas's population drive political movements in the US during the mid-19th century?

In the mid-19th century, Texas's demographic makeup, characterized by a mix of Anglo settlers, Mexican residents, and enslaved African Americans, significantly influenced political movements. The influx of Anglo settlers, driven by Manifest Destiny and land opportunities, fostered a push for Texas's annexation to the United States, which was seen as a means to expand slavery. This diverse population also led to tensions over issues of sovereignty, land rights, and cultural identity, fueling political debates and movements related to statehood, slavery, and relations with Mexico. Consequently, these dynamics contributed to the broader sectional conflicts that eventually culminated in the Civil War.
