The political developments after the 1990s in India witnessed significant changes in the political landscape of the country. One of the major developments during this period was the emergence of Congress dominance. Let us analyze this in detail.

Emergence of Congress Dominance:
1. Historical Context:
- The Indian National Congress (INC) had played a pivotal role in the freedom struggle and had a strong presence in the political arena even after independence.

- The Congress Party, under the leadership of Prime Minister P.V. Narasimha Rao, initiated these reforms, which brought about significant changes in the Indian economy.
- The economic reforms helped in stabilizing the economy, attracting foreign investments, and promoting economic growth.

3. Political Stability:
- The Congress Party, with its vast experience and organizational strength, was able to provide political stability during this period.
- The party successfully navigated through various coalition governments at the center and managed to form alliances with regional parties.

4. Electoral Performance:
- The Congress Party witnessed electoral success in the 1991 general elections, where it won a significant number of seats and formed a minority government.
- The party's success can be attributed to its ability to adapt to the changing political scenario and connect with the aspirations of the people.

5. Regional Dynamics:
- The emergence of regional parties and the rise of coalition politics was another significant development during this period.
- However, despite the rise of regional parties, the Congress Party managed to maintain its dominance by forming alliances with them and incorporating regional issues in its agenda.
