George Washington was aware that many of his actions would be regarded as precedents. Here are three precedents that Washington established:

Washington created the first Presidential Cabinet.  Who was on the Cabinet, and what Departments did they represent?  Who is on the Cabinet today, and what Departments do they represent?
Washington was the first President to leave office after two terms.  Is that precedent still followed today?  Why or why not?
Washington was the first to establish foreign policy, and issued the Proclamation of Neutrality.  What situation did this proclamation address?  What agency advises the President on foreign policy today?  What is the role of this agency?
