In The Federalist Paper n. 51 James Madison explained and defended the checks and balances system in the new Constitution. The Checks and Balances system consists of each branch of the government has a power to check the power of the other two branches, each branch of the government is dependent on the people who are the source of legitimate authority.
This was very important because it was a revolutionary feature that influenced the US Constitution and other Constitutions around the world.
