The saffron party's previous best performance was in 1987 when it won 16 of the 20 seats it had contested.
This time, riding on Modi wave, BJP foiled the efforts of Bhupinder Singh Hooda's Congress government to retain power for the third successive time.
The saffron party had won only four seats in the previous Assembly election in 2009.
Though Hooda was confident of getting the third term, Congress' performance had declined in the 2009 Assembly poll as well compared to its performance in the 2005 election.
Even in the previous assembly poll five years ago, Congress had fallen short of majority with only 40 seats in the 90-member House (as against 46 seats required for simple majority). Om Parkash Chautala-led INLD finished second with 31 seats.
The remaining 29 seats were shared by Haryana Janhit Congress-BL six, BJP four, SAD and BSP one each and Independents seven.
But, Hooda managed to form the government after five Haryana Janhit Congress (BL) MLAs deserted their party and merged with Congress which also got support of seven Independents and a lone BSP member.
