George Washington, who had led the war, became its first president. During the 19th century, the United States gained much more land in the West and began to become industrialized. In 1861, several states in the South left the United States to start a new country called the Confederate States of America.

Answer 2

Nation state (or nation-state), in the most specific sense, is a country where a distinct cultural or ethnic group (a "nation" or "people") inhabits a territory and have formed a state (often a sovereign state) that they predominantly govern. It is a more precise term than "country" but of the same general meaning, being that it is an ethnic nation with its own land (thus "homeland") and government.
