The ten amendments created became the bill of rights. These were the standard that were signed off and now should be followed by every citizen. Breaking it can lead to very bad consequences.
10 years after the Bill Of Rights were created, Thomas Jefferson wanted more to be added to the Constitution. As it was they were perfecting the Constitution waiting for it to be all signed and complete.
The Constitution was created because one was to create the government such as The Legislative Branch, The Executive Branch, and The Judicial Branch. it was also created because it wanted to give equal fair rights between the federal government and the citizens.
The way the constitution was created was that each of the Founding Fathers wrote their own part about how the power should be made. After the Fathers would work together to see if it was necessary to do or if adjustments needed to be made. At the very bottom of the Constitution, the signatures were signed from all of the Founding Fathers.
