What prevents one branch of government from becoming too powerful?

The concept that prevents one branch of government from becoming too powerful is known as checks and balances. This system is integral to the structure of the U.S. government, as it ensures that each branch—executive, legislative, and judicial—has the ability to limit the powers of the others. This prevents any single branch from exercising unchecked authority and helps maintain a balance within government operations.

For example, the legislative branch has the power to create laws, but the executive branch can veto legislation. Meanwhile, the judicial branch can declare laws unconstitutional, thus invalidating them. This interplay means that cooperation and compromise are needed to govern effectively, promoting accountability and preventing tyranny.

Other concepts, like judicial review, while significant, are a component of the checks and balances system rather than an overarching system in itself. Federalism refers to the division of powers between national and state governments, and majority rule pertains to decision-making in a democracy but does not safeguard against the concentration of power within a single branch.
