Why did our founders not want a president under the articles of confederation?

When we think of the President of the United States, many people do not realize that we are actually referring to presidents elected under the U.S. Constitution. Everybody knows that the first president in that sense was George Washington. But in fact the Articles of Confederation, the predecessor to the Constitution, also called for a president- albeit one with greatly diminished powers. Eight men were appointed to serve oneyear terms as president under the Articles of Confederation. In November 1781, John Hanson became the first President of the United States in Congress Assembled, under the Articles of Confederation.
