As far as the two party system it came up rather quickly. Sorta as groups around particular personalities that kinda solidified into parties. The way I understood it the founding fathers had actually though each state would be putting forth favorite sons for president and they thought every election would be a battle royale. They though representatives in congress would be more about state they are from than a party. I can say even in my lifetime congressmen have become less and less about state and more and more about party. Also senators, representatives, judges, and presidents use to view each other as rivals and would go against (chastise) a president who overreached, even in their own party, to tell them to stay out of their dominion and stay in their lane.
