<em>The concepts of checks and balances were established by the authors of the Constitution so that no single branch of the government would gain too much power.</em>
This concept is a valuable precept because with the checks and balances can prevent wrongdoings from the other parts of the government and the exercise of power is divided equally.

The difference between the Articles of Confederation and Constitution is that the Articles of Confederation are the rules that were agreed by the United States of America in the 18th century whereas the constitution is the rules that democratic countries and other legalized institutions develop to implement law and order in their body.
