Which issue did Texans and other Americans face after the United States gained new territories from Mexico in 1848?

After the United States gained new territories from Mexico in 1848, Texans and other Americans faced several issues.

1. Slavery: The most significant issue was whether these new territories would allow slavery. The North and South had different views on this matter, leading to increased tensions between the two regions. The North wanted the new territories to be "free states," while the South wanted to expand slavery into these areas.

2. Land Disputes: There were also disputes over land ownership. Many Mexican citizens already living in these territories had claims to the land, but these were often ignored or overridden by incoming American settlers, leading to conflict.

3. Cultural Differences: There were significant cultural and language differences between the incoming Americans and the existing Mexican population. This led to social tensions and difficulties in integrating the two groups.

4. Economic Issues: The new territories were rich in resources, leading to competition and conflict over control of these resources. This was particularly true in California, where the Gold Rush began shortly after the territory was acquired.

5. Political Power: The addition of new territories also led to a rebalancing of political power within the United States. There was a lot of debate over how these new territories should be governed and how they would be represented in Congress.
