Contribution of National and Regional political parties in Nation building

The presence of a political party is a mandatory condition, without which there is a government conducting and other political activities appear impossible. The role and functions of political parties vary with the basis of different types of political ideologies. Their work is different in both non-democratic, political ideology and democratic political ideology. There are some political parties whose existence can be seen in the entire country, they are called national parties, and political parties whose existence or influence is limited to one or two states are called state-level parties.
