rdf:langString Names of the United States

rdf:langString Several names of the United States of America are in common use. Formal alternatives to the full name include the "United States", "America", as well as the initialisms "U.S." and the "U.S.A."; colloquial names include "the States" and the "U.S. of A." It is generally accepted that the name "America" derives from the Italian explorer Amerigo Vespucci. The term dates back to 1507, when it appeared on a world map created by the German cartographer Martin Waldseemüller, in honor of Vespucci. The full name "United States of America" was first used during the American Revolutionary War, though its precise origin is a matter of contention. The newly formed union was first known as the "United Colonies", and the earliest known usage of the modern full name dates from a January 2, 1776 letter written between two military officers. The Articles of Confederation, prepared by John Dickinson, and the Declaration of Independence, drafted by Thomas Jefferson, both contain the phrase "United States of America." The name was officially adopted by the second Continental Congress on September 9, 1776.
