55 delegates met together on May 25, 1787 in Pennsylvania in the state house to originally revise the Articles of Confederation but made a completely new thing. They first elected George Washington as president and then came up with a rule of complete secrecy.
I will rule the people for four years! Yay!
The idea of three branches, the legislative, executive, and judicial branch in government came up and then two plans were proposed; the Virginia Plan, stating legislative should have two houses based on population and the New Jersey Plan, stating only one legislative house not based on size
The Great Compromise incorporated both state plans, stating that the House of Representatives based on population and the Senate was a fixed number of two. Another compromise made was that congress could not tax exports and could not interfere with the slave trade.
Another argument arose between the delegates; how many people should lead the people, three versus one. Eventually, a conclusion of one came around and it was also decided a president would serve for four years and be elected by a system called the electoral college system.
A conclusion between the delegates was made that nine out of the 13 states had to pass or approve the constitution. On September 17, 1787, the delegates declared the constitution complete.
