What challenges did US face in expanding after 1789?

Answer 1

After 1789, the United States faced several challenges in its expansion, including conflicts with Native American tribes, who resisted encroachment on their lands. Additionally, there were internal divisions over the expansion of slavery into new territories, which fueled sectional tensions. Geopolitical rivalries with European powers, such as Spain and Britain, also complicated expansion efforts. Lastly, the need for infrastructure and governance in newly acquired territories posed significant logistical challenges.
