As usual, I prefer the politically incorrect:
This country was started BBB (in the Brothels and Bars of Boston). The first time the colonies were called United States in a formal document, John Hancock was president of the Continental Congress. John Hancock signed The Declaration of Independence twice. First as president of The Continental Congress and then the big signature as the representative of Massachusetts. Though Hancock was a smuggler, he should not be dismissed as not being very important in our history. Hancock had the Articles of Confederation being worked up about a year before we declared independence.
Mentioning the Articles of Confederation is the political incorrectness. I do not know the sequence of presidents before the second Continental Congress enacted the Constitution and Washington was inaugurated.
