What was proposed as a basic framework of the national government by James Madison and other delegates?

James Madison and other delegates proposed a framework for the national government that emphasized a system of checks and balances among three branches: the legislative, executive, and judicial. This structure aimed to prevent any one branch from gaining too much power and to ensure a separation of powers. Additionally, the framework included a strong central government while still preserving certain rights for states and individuals, as seen in the Virginia Plan, which served as a basis for discussions during the Constitutional Convention.
