Rules and laws are essential for the welfare of the society and nation. From olden times itself, the kingdom or monarchy has been set for governing the affairs and leading the country to the path of prosperity. The duty of today’s government is more or less the same. But the system prevailing today has been the result of a series of evolutions which were judged by the people from time to time. Various systems of government exist today in different nations, but there are certain features in common. Many of the governing systems ensure the active participation of people and the citizens enjoy a major role in the formation of governments.
