There seems to be no specific or any unified theory to explain what decentralization is about and how it operates. The idea of decentralization emerged in 1950s with Riggs (1956), Maddick (1963) and the United Nations (1962) and etc., and those seem to be influenced by neoclassical economic writings. During the late 1970s and the 1980s the subject had become a popular strategy in the field of development administration. Rondinelli and Cheema (1983) Rondinelli, Nellis and Cheema (1983) and Mawhood (1983) see decentralization as organizational arrangements. Slater (1989), Smith (1985) and Conyers (1983) viewed the term as relatively related with politics, which has much wider role to play.
