The governing body of the American democracy is the Congress. It is composed of the Senate and the House of Representatives, and works in the Capitol Hill, in the picture above.
Many researchers derive democracy from ancient Greece. How would ancient Greece compare with modern America?
Ancient Greeks actually developed a proto-democracy: they happened to have city-states, kings or queens, and depended heavily at times on military leaders and bequeathed elitism.
There have been no kings or queens of the USA. The head of the state is the President, who resides in the White House.
Washington D.C. is the capital of the USA. District Columbia is on the American East Coast. The state of Washington is on the West Coast. We can get maps of the USA at the National Atlas website, NATIONAL ATLAS.GOV.
There are many places named Washington, in the United States. ■George Washington remains a prominent figure. He fought for American freedom in the Revolutionary War against England. He was President in years 1789-1797, the first head of state after the War of Independence.
The Revolutionary War had its written formulation in the Declaration of Independence. The Revolutionary victory brought another prominent writing, the United States Constitution. Feel welcome to the ■Civics for grammar.
United States government was built “from scratch” by the ■Framers:
The constitutional reallocation of powers created a new form of government, unprecedented under the sun. Every previous national authority either had been centralized or else had been a confederation of sovereign states. The new American system was neither one nor the other; it was a mixture of both — reports Wikipedia after historian Forrest McDonald.[40]
The new form of government is ■democracy, more advanced than Greek prototypes. We may care to see the ■Federalist reflections by ■James Madison.
