How did george washington create a model for the american presidency?

Hey there!
If we think about it, Washington was the guy. He was the full on icon for Presidency.
He led the Continental Army to victory against the full might of the British Empire, came from humble beginnings, and rose up through the ranks and became the person that the citizens of the newfound country of America wanted to rule them.
In terms of leadership, he was an intellectual.
He knew how to lead people, and what was best for them. He was one of the reasons America was able to stand up to the British and fight for their freedom. He had a vision for a democratic country, led by the people, for the people.
I hope this helps!
