Separation of powers is a constitutional principle that divides government authority among three distinct branches—the legislative (Congress), executive (President), and judicial (Supreme Court)—to prevent any single branch from accumulating excessive power and becoming a 'usurper.' This system, championed by Enlightenment thinker Baron de Montesquieu in his 1748 work 'The Spirit of Laws,' ensures checks and balances where each branch has specific powers and limitations: Congress declares war, collects taxes, and regulates trade; the President enforces laws and serves as commander-in-chief; and the judiciary interprets laws and exercises judicial review to declare unconstitutional acts.
