The role of regional parties changed over period of time. The changes are as follows:
After independence, regional identity gave rise to separatists movements and demands were put up by regional parties for separate state.
They wanted to break away from the Indian union and form a separate state.
The demands of the regional parties changed gradually and these parties started asking for autonomy.
In the later period, for the development of their region and people the parties demanded representation of their people in the state and central government.
Regional parties in the north eastern region also started demanding more autonomy after split up.
The journey of the regional parties began with a split up and then a demand for autonomy going on to share power in federation and then entry into mainstream national politics.
