What system of government divides power among different levels rather than giving all power to a central government?
Actually, just about every government has to do this to some extent or another. No single central government can control everything. In order to function all governments must delegate power to lower levels. If they don’t, then the central government will become so bogged down the the minutia of day-to-day matters that it will not be able to deal with the bigger matters. However, I suspect that this is not the answer for which your teacher is looking. I suspect that the answer that he/she wants is a federal system of government such as we have in this country. In a federal system, the central government is primarily tasked with dealing with foreign countries and regulating the relationships between the various states. Beyond this the individual state are supposed to pretty much take care of everything else. (This delegation of powers has been eroded quite a bit since the Constitution was first written.
It is a democracy government. Although it is rule by the people, democracies usually follow the social contract theory. John Locke was the philosphor of this theory. This theory states that the powers are seperated and are given to more than one system of government, and where the people are mostly the power. This also states that men were naturally free and have basic natural rights for freedom, pursuit, and happiness. The United States is a great example of a democracy that developed the social contract theory. It was first leaded by the Magna Carta, followed by The Petition of Rights, The English Bill of Rights, and finally resulted in the Declaration of Independence.
