What do you mean by a coalition government?

The political parties are the pillars of a democracy. In a large country like India, it is difficult for any one party to accumulate majority votes. They need to form alliances with other parties.

The government formed with the alliance of several parties is called a coalition government.

Example: The Bhartiya Janta party was founded in 1980. The party came into power in 1998, with the support of various regional political parties. The alliance of BJP with various state parties was named as National Democratic Alliance.
