The concept of political change is operated in the democratic countries by peaceful or constitutional means mainly through elections. India politics is closely related to its geographical expression of heterogeneity and pluralism. The diversity is marked by multiplicity of communities, caste and sub-castes, ethnic groups, linguistic groups, different regions and sub-regions with varying economic indices etc. Thus India presents an authentic plural society, striving hard to secure the long cherished goal of national integration through a federal democratic, parliamentary paradigm. At the national level there has been a significant change in regard to the political fortunes of different political parties. The domination of Congress was an uninterrupted phenomenon, which slowly transformed into that of a prominent Congress model and by nineties it was eclipsed to a great extent.

Until 1983 it was the dominance of Congress party, but a shift is marked with the advent of regional Telugu Desam Party with the capture of political power in a most spectacular way.
