Who picked the name "The United States of America"? And when was it chosen?

Question

In 1776, the Declaration of Independence was written under the name "The United States of America", but when and who chose the name? When was it officially adopted?

Answer 1

The U.S. Constitution was officially adopted on June 21, 1788 when New Hampshire became the ninth state to ratify.
The Constitution is titled "The Constitution of the United States of America".
Thomas Jefferson is considered to be the principal author of the Declaration of Independence. James Madison is considered to be the author of the U.S. Constitution.

Answer 2

Actually, it is the SEVERAL States of America.

The original 13 COLONIES, which were the only political entities at the time the Constitution was written, were NOT States until they were raised to that status by the Constitution... at that time the States stood UNITED in a single cause.

At that time, and still today, the SEVERAL STATES of America are considered as FOREIGN COUNTRIES to each other... this is why each State can write it's own laws and make it's own foreign contracts.

The Federal Government only exists to deal with INTERSTATE commerce or problems while the SEVERAL State Governments are free to deal with INTRASTATE problems.

This was also the basis of the problems leading to the Civil War... The STATES RIGHTS which are granted to the SEVERAL STATES by the U.S. Constitution... was in conflict with the laws governing the individual States.
