Question

While the House of Representatives had a majority of Northerners in 1819, admitting any new state, either slave or free, would upset the balance in what?

Answer 1

Admitting a new state into the Union would upset the balance of the Senate.

Answer 2

Senate

Step-by-step explanation:

The seats in House of Representatives were given to states based on their populations. However, the Senate operated differently. In the Senate, each state had the same number of representants. This meant that, if a new state was admitted, the balance between free and slave states would be altered. This concern led to what is known as the Missouri Compromise.
