Question

Also, what precedents did washington set as a president? What was the result of the XYZ affair, and what caused two political parties to develop?

Answer 1

Under the Jay Treaty, both sides achieved many objectives. The British agreed to vacate the six western forts by June 1796 (which was done), and to compensate American ship owners (the British paid $10,345,200 by 1802). In return, the Americans gave most favored nation trading status to the British, and acquiesced in British anti-French maritime policies. The United States guaranteed the payment of private prewar debts owed by Americans to British merchants that could not be collected in U.S. courts (the U.S. paid £600,000 in 1802). Two joint boundary commissions were set up to establish correctly the boundary line in the northeast (it agreed on the Saint Croix River) and in the northwest (this one never met).

The balance of your question is too complicated to answer here.
