The U.S. has federal states just as in Germany does. States which are created by the U.S. which are distinct from the creator(s) of the U.S. With Germany, there are are the federal states which are creatures of the republic that was created by the "Lander" which are NOT federal states. When the lander and the federal states have the same name.... it gets 'interesting'.
However, with Missouri, Arkansas, Colorado, Louisiana it might get even more interesting because a French Colony preceded Missouri, Arkansas, Kansas, Nebraska, etc rather than a British Colony.
The term "States of the Union" (which is called the United States) can refer to federal states created by the United States rather than referring to any creator of the United States. Whereas it might be safe that the states of America are not creations of the United States.Follow the yellow brick road.
