How was the federal government originated under the Constitution?

The federal government was established under the Constitution in 1787 as a response to the weaknesses of the Articles of Confederation, which had created a loose confederation of states with limited central authority. The Constitution created a stronger federal framework with three branches—executive, legislative, and judicial—to balance power and prevent tyranny. It also incorporated a system of checks and balances, ensuring that no single branch could dominate the government. Ratified by the states, the Constitution laid the foundation for a more unified and effective national government.
