Why was there an uproar when Missouri applied to join the union in 1819 as a salve state?

Answer 1

The uproar over Missouri's application to join the Union as a slave state in 1819 stemmed from the contentious debate over the expansion of slavery into new territories. This issue intensified sectional tensions between the North, which opposed the spread of slavery, and the South, which supported it. The crisis ultimately led to the Missouri Compromise of 1820, which aimed to maintain a balance between free and slave states. The controversy highlighted the deepening divide in the nation over slavery, foreshadowing future conflicts.
