United States in 43 historical maps
The United States of America (USA) are named after the Italian explorer Amerigo Vespucci. The name America was introduced by the German cartographer Martin Waldseemuller. The name appeared for the first time on his famous world map published in 1507. The printed wall map was lost for a long time; the only survived copy was found in Schloss Wolfegg, in southern Germany in 1901. The map, also called the "birth-certificate of America", was purchased by the Library of Congress in 2003. The Eastern coastline of (Northern) America was drawn much more accurate on the world map of Ribero in 1527. The first separately printed map of the new continent (the Americas) was included in Sebastian Munster’s encyclopedia (1540 onwards). The first separate maps covering the area of present day United States appeared at the end of the 17th century. The name United States of America was introduced after their independence from the UK in 1776.
