WHY AMERICA IS CALLED UNITED STATES
The name 'United States of America' was chosen to reflect the union of the thirteen original colonies that formed the country.
The name 'America' was already used to refer to the continent, thus adding 'United States' helped identify the country.
The name also underlined the country's federal structure, with the central government and states sharing authority.
The Declaration of Independence used the word in 1776, but the Constitution in 1788 made it the US.
The name has become a symbol of American identity and unity, and is often used in patriotic contexts.
The name has also been attacked for implying that the US is the only legitimate representation of the American continent.
