Partap Singh Kairon (1 October 1901 – 6 February 1965)^[1] was the 3rd Chief Minister of the Punjab province (then comprising Punjab, Haryana and part of Himachal Pradesh), and is widely acknowledged as the architect of post-Independence Punjab Province (or Punjab, Haryana and Himachal as of today). Moreover, he was an Indian independence movement leader. He was jailed twice by the British Empire, once for five years for organizing protests against British rule. His political influence and views are still considered to dominate politics in Punjab.^[2]

Partap Singh Kairon was born on 1 October 1901, into a Dhillon Jat Sikh family.^[3] His last name was taken from the village of Kairon in the Amritsar district, of Tehsil Tarn Taran in province of Punjab during the British Raj era.^[4] His grandfather was Sardar Gulab Singh Dhillon. His father, Nihal Singh Kairon (1863-1927), was a pioneer in initiating women's education in the province. Partap studied at Col. Brown Cambridge School in Dehra Dun and Khalsa College, Amritsar and then went to the United States for further studies. During his time in USA, he supported himself by working on farms and in factories. He received his Master's degree in political science from the University of Michigan. He also received his Master's degree in Economics from University of California at Berkeley before going to Michigan. He was impressed by farming methods practised in the U.S.A and hoped to replicate the same in India later.

Partap Singh Kairon had 3 children, including Surinder Singh Kairon, Gurinder Singh Kairon and Sar Brinder Kaur respectively. While the younger Gurinder remained Congressman like his father, Surinder later joined Shiromani Akali Dal. Surinder's son Adesh Partap Singh Kairon is married to the daughter of Prakash Singh Badal, Preneet Kaur and has been a minister in the Punjab government (Shiromani Akali Dal).^[5][6]

In 1964, following the publication of the report of the commission of inquiry which had exonerated him of the bulk of the allegations made against him by his political adversaries, Partap Singh Kairon resigned from his position as chief minister of the Punjab.

On 6 February 1965, he was on his way from Delhi to Chandigarh when he was waylaid near Rasoi village, Sonipat district, and shot dead along with his personal assistant — an IAS officer, and the driver. The three were murdered by Sucha Bassi, Baldev Singh and Nahar Singh 'Fauji'.^[7] Sucha had planned the killing of Kairon in revenge, because he believed that Kairon had taken a personal interest in securing the conviction of one Ajit Singh and his father Bir Singh in a murder case. Sucha Bassi, Baldev Singh and Nahar Singh 'Fauji' — were convicted and hanged in 1970, while the fourth accused, Daya Singh was sentenced to life imprisonment and released in 1994.^[8]
