Since India's independence in 1947, its political system has undergone significant changes. Some major developments are:

• Adoption of the Constitution in 1950, establishing India as a sovereign, democratic, and republican state.
• The emergence of the Indian National Congress as a dominant political force in the first few decades after independence.
• Introduction of the two-party system with the formation of the Janata Party and the Bharatiya Janata Party in the late 1970s and early 1980s.
• Implementation of the Mandal Commission report in 1990, which gave reservations to other backward castes in government jobs and educational institutions.
• The liberalization policy of 1991, which opened up the Indian economy to foreign investment and reduced the role of the public sector in certain industries.
• The rise of regional parties and coalition governments at the state and national levels in the late 1990s and early 2000s.
• The implementation of the Goods and Services Tax (GST) in 2017, which replaced multiple indirect taxes and created a unified market throughout the country.

Despite these changes, India's political system remains complex and multifaceted. The country continues to grapple with issues related to corruption, communalism, and economic inequality.
