George Washington's Oath of office explanation

The United States of America was first born when The Articles of Confederation were adopted on March 1, 1781 and served as the form of government for the first 8 years of the new nation's history:

Articles of Confederation

To all to whom these Presents shall come, we the undersigned Delegates of the States affixed to our Names send greeting.
Articles of Confederation and perpetual Union between the states of New Hampshire, Massachusetts-bay Rhode Island and Providence Plantations, Connecticut, New York, New Jersey, Pennsylvania, Delaware, Maryland, Virginia, North Carolina, South Carolina and Georgia.

I.

The Stile of this Confederacy shall be
"The United States of America"

The United States Constitution was written in 1787 during the Philadelphia Convention. After ratification in eleven states, in 1789 its elected officers of government assembled in New York City, replacing the earlier 1781 Articles of Confederation government. Following its establishment, the original Constitution has been amended twenty-seven times. The meaning of the Constitution is interpreted and extended by judicial review in the federal courts. An original copy of the parchments is held at the National Archives Building.

Who ordained the constitution for the United States of America??  We the People of the United States.

We the People  of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America.

Article II is the only time (other than the Preamble) that the United States of America is mentioned in the Constitution, even though the style of the name of the union of states was United States of America, in the Articles of Confederation,  and the constitution is ordained for the United States of America.  The use of particular words were no accident.

Article II

Section 1

1:  The executive Power shall be vested in a President of the United States of America.  He shall hold his Office during the Term of four Years, and, together with the Vice President, chosen for the same Term, be elected, as follows:

George Washington took his oath on April 30, 1789, as it is prescribed by article 8:

8:  Before he enter on the Execution of his Office, he shall take the following Oath or Affirmation:--“I do solemnly swear (or affirm) that I will faithfully execute the Office of President of the United States, and will to the best of my Ability, preserve, protect and defend the Constitution of the United States.”

Not only did George Washington take his oath to faithfully execute the Office of President of the United States, but also to peserve, protect, and defend the Constitution of the United States  - - - but this is the constitution for the United States of America. And every president after him has taken the same oath.
