The United States Constitution led to a stronger central government, a bicameral legislature, three branches of government, and a division of power between the states and the central government. It also lead to a more stabel economical stance due to the government being able to tax. The United States Constitution also gave small states a voice against bigger states. The Constitution also created a practicle way of passing laws and making amendments. Laws were passed if they got a two thirds majority vote instead of everyones vote.
this was made very easy for them to do so they did it and it made sense
