United States [SEP] Etymology
The first known use of the name "America" dates back to 1507, when it appeared on a world map created by the German cartographer Martin Waldseemüller. It comes from the given name of Italian explorer Amerigo Vespucci, who was the first to postulate that the West Indies did not represent Asia's eastern limit, but part of a previously unknown landmass. The full name "United States of America" dates to the Revolutionary War. The second draft of the Articles of Confederation, prepared by John Dickinson, and Thomas Jefferson's original rough draft of the Declaration of Independence both included the name. However, it is unclear which of these two usages came first.
