The body was founded in 1966, when the state was created from part of the state of Punjab, by the
Punjab Reorganisation Act, 1966. The house initially had 54 seats, ten reserved for
scheduled castes, this was increased to 81 seats in March 1967, and to 90 seats (including 17 reserved seats) in 1977. The highest number of seats ever won was in 1977 when
Janata Party won 75 out of 90 seats in the aftermath of the
1975–77 emergency by
Indian National Congress's (INC)
Indira Gandhi. INC won only 3 seats,
Vishal Haryana Party and independents both won 5 seats each. Since the formation of Haryana in 1966, the state politics became infamously dominated by the
nepotistic clans of five
political dynasts, Lal trio (
Devi Lal,
Bansi Lal and
Bhajan Lal) as well as the
Hooda clan and
Rao Birender clan. The
Mewat region, remotely to the rest of Haryana since its formation, has been dominated by three major political dynasts (
Tayyab Husain,
Rahim Khan,
Khurshid Ahmed). The infamous
Aaya Ram Gaya Ram politics, named after
Gaya Lal in 1967, of frequent
floor-crossing,
turncoating,
switching parties and
political horse trading within short span of time became associated with Haryana. == Floor Leaders and Ministers ==
