The USA is the world’s foremost economic and military power, with global interests and an unmatched global reach.
America’s gross domestic product accounts for close to a quarter of the world total, and its military budget is reckoned to be almost as much as the rest of the world’s defence spending put together.
The country is also a major source of entertainment: American TV, Hollywood films, jazz, blues, rock and rap music are primary ingredients in global popular culture.
The United States originated in a revolution which separated it from the British Crown. The constitution, drafted in 1787, established a federal system with a division of powers which has remained unchanged in form since its inception.
