Prior to the adoption of the Articles of Confederation, representatives of the British colonies in America met in a Continental Congress. The “United Colonies of America” elected the following presidents:
September 5, 1774 to October 22, 1774
Henry Middleton October 22, 1774 to October 26, 1774 (filling in for a sick Randolph)
Peyton Randolph May 20, 1775 to May 24, 1775 (he chose to leave to preside over the Virginia House of Burgesses)
John Hancock October 27, 1775 to July 1, 1776
After the Declaration of Independence, when the colonies officially became the United States of America, there were yet more presidents:
July 2, 1776 to October 29, 1777
Henry Laurens November 1, 1777 to December 9, 1778
John Jay December 10, 1778 to September 28, 1779
Samuel Huntington September 28, 1779 to February 28, 1781
When the Articles of Confederation, formally called “Articles of Confederation and Perpetual Union,” established the United States of America as a confederation of sovereign states and were adopted by all parties in March of 1781, Samuel Huntington was chosen to continue as President of the United States. He only served from March until July, however, because of poor health.
Next, Thomas McKean served from July until November 4th. (McKean, also the Chief Justice of Pennsylvania, agreed only to serve until his court commenced in late October.) John Hanson was then chosen unanimously, and was the first President of “the United States” to serve a full year.
[The Articles of Confederation only allowed a President to serve a one-year term during any three-year period, so Hanson served in that office from November 5, 1781 until November 3, 1782.]
Hanson’s successors were as follows:
4th President of the United States
in Congress Assembled
November 4, 1782 to November 3, 1783
Thomas Mifflin 5th President of the United States in Congress Assembled November 3, 1783 to June 3, 1784
Richard Henry Lee 6th President of the United States in Congress Assembled November 30, 1784 to November 23, 1785
John Hancock 7th President of the United States in Congress Assembled November 23, 1785 to June 6, 1786
Nathaniel Gorham 8th President of the United States in Congress Assembled June 1786 – November 13, 1786
Arthur St. Clair 9th President of the United States in Congress Assembled February 2, 1787 to October 29, 1787
Cyrus Griffin 10th President of the United States in Congress Assembled January 22, 1788 to March 4, 1789
Following the ratification of the Constitution by the required nine States, George Washington was inaugurated on April 30, 1789 as the first President of (the Constitutionally-defined) United States.
