After 1990, Indian politics saw a rise of regional political parties in many states. It was also the beginning of the era of Coalition Government at the Centre. A Coalition Government is a Cabinet of a Parliamentary Government in which several political parties cooperate. The usual reason given for this arrangement is that no party on its own can achieve a majority in the Parliament.A Coalition Government might also be created in a time of national difficulty or crisis.
A coalition government is one which is formed by the coming together of at least two political parties. Usually, it is the partners in an electoral coalition that form a political alliance and adopt a common political programme.
