United States of America

United States of America appears on the map from 1776 to today. At its greatest recorded extent, in 1945, it covered about 12.19 million km².

Thirteen British colonies along the Atlantic coast declared independence on 4 July 1776 and won it in the Revolutionary War with French help. The Constitution of 1787 created a federal republic with an elected president, Congress and courts, and George Washington became the first president in 1789. The young nation expanded westward through the Louisiana Purchase in 1803, war with Mexico in 1846–48 and the acquisition of Oregon and Alaska, displacing Native American nations by force and treaty.
