Which elections marked the end of Congress system in India?

1989

The correct answer is option (2) - 1989

The elections held in 1989 marked the end of what political scientists have called the ‘Congress system.

The primary turning point during this era (1990s) was the Congress party's defeat in the 1989 elections. After securing a significant 415 seats in the Lok Sabha during the 1984 elections, the party's representation plummeted to a mere 197 in this subsequent election. Although the Congress managed to regain power after the mid-term elections of 1991, the 1989 elections marked the conclusion of what political analysts refer to as the 'Congress system'.
