The Imperial Presidency by Arthur M. Schlesinger, Jr

A critique of the twentieth-century growth of executive power into an 'imperial' presidency, tracing how crises (the Great Depression, World War II, and the Cold War era) and institutional changes concentrated authority in the Oval Office; it examines the expansion of secrecy, unilateral military action, emergency powers, and the erosion of congressional oversight and judicial checks, uses historical examples and contemporary controversies to argue that unchecked executive autonomy endangers constitutional democracy, and calls for reforms—stronger legislative oversight, judicial enforcement, transparency, and limits on wartime and emergency authority—to restore proper separation of powers.
