1. Prundential reasons: (a) Prundential reasons are based on careful calculations of gains and losses. For example, in the Nepal movement for democracy even the Maoists, an armed revolutionary group, was given some share after the formation of government. The major gain for this was peace in Nepal. (b) Prundential reasons help to reduce the possibility of conflict between social groups. (c) Prundential reasons are good way to ensure political stability. (d) Imposing the will of majority community over the majority may look like an attractive op³tion in the short run, but in the long run, it undermines the unity of the nation. Tyranny of the majority is not just oppressive for the minority; it often brings ruin to the majority as well 2. Moral reasons: (a) Power sharing is the basic spirit of democracy. A democratic rule involves the sharing of power with those who have to live with its effects. (b) A democratic government is chosen by the people. So they have the right to be consulted on how they are to be governed. A legitimate government is one where groups, through participation acquire a stake in the system. (c) Decentralisation of power, i.e., formation of state government, local governments is an example of moral reason.
