The United States of America is a federal republic of 50 states, a federal district and 14 territories. It is located mostly in central North America. The U.S. has three land borders, two with Canada and one with Mexico, and has sea borders with Cuba, the Bahamas, the Dominican Republic, Bermuda and Russia, and is otherwise bounded by the Pacific Ocean, the Bering Sea, the Arctic Ocean and the Atlantic Ocean. Of the 50 states, only Alaska and Hawaii are not contiguous with any other state. The U.S. also has a collection of districts, territories, and possessions in the Caribbean Sea and Pacific Ocean. Each state has a high level of autonomy according to the system of federalism. The U.S. traces its national origin to the declaration by 13 British colonies in 1776 that they were one free and independent state. They were recognized as such by the Treaty of Paris in 1783. Since then, the nation has grown to become a superpower and exerts a high level of economic, political, military, and cultural influence.
