The framers disagreed upon many issues during the creation of the constitution, but they were most concerned about state representation, creating checks and balances within the centralized government, avoiding giving the central government too much power that would interfere with people's basic rights and the development of the court system. To create a system of checks and balances, the three governmental branches were created: judicial branch (to keep order), legislative branch (to create laws) and executive branch (to govern).
The largest disagreement perhaps amongst the framers was the issue of state representation. This issue could not be solved quickly as the creation of a checks and balances system had been. The framers soon found that the larger state delegates wanted to use population numbers to decide how many people would be chosen as delegates for Congress. However, the framers who were from smaller states felt that they would not be able to make a difference in the legislative branch if the larger states were given too much additional power.
To solve the disagreement of the delegates in Congress, the framers decided to create two parts to the legislative branch. These two parts were the Senate and the House of Representatives. The Senate would allow two delegates from each state regardless of size while the House of Representatives would have a fixed number of delegates that would be divided amongst states based on the overall population size in each state.
