The Function Of a Constitution. A constitution is a written document that sets forth the fundamental rules by which a society is governed. For the purposes of this paper, the most important function of a constitution is the creation and delimiting of a political entity. This paper concludes that constitutions are not a cure-all but they function to allow states to rise above ethnic, geographic, and regional diversity. They do this by providing a political framework for the governmental life of the nation to operate on; they also act, at their best, as embodiments of the national character, and symbols of the state. 9 pgs. 18 f/c. 6b.
