Born at Patiala City in Patiala State, within the British Raj (now in Punjab, India) in 1914 into a Sikh Jat family of the Sidhu clan, Maharaja Yadavindra attended Aitchison College in Lahore.
He served in the Patiala State Police, became its Inspector General and served in Malaya, Italy and Burma during the Second World War.

Yadavindra Singh was the ninth and last ruling Maharaja of Patiala from 1938 to 1971.
He succeeded his father, Maharaja Bhupinder Singh, as the Maharaja of Patiala on 23 March 1938 and subsequently married his second wife, Mehtab Kaur (1922–2017), in 1938.
Although the stated reason for his second marriage was that it was due to his first wife being issueless, it was believed that the actual reason was the influences of Akali leaders who wanted the future Maharaja of Patiala to marry a woman from a Jat Sikh family in order to beget genuine Sikh heirs.
Yadavindra served as president of the Indian Olympic Association from 1938 to 1960.
He was instrumental in organizing the Asian Games.
He was a noted horticulturist by passion and later served as chairman of Indian Horticulture Development Council.

At a special session he said "After centuries time has come when India has gained independence from foreign rule and it's the time when we all (princely states) should unite for our motherland" and persuaded many other rulers to join India.
During the Partition of India numerous pogroms occurred in and around the princely state of Patiala.
In several cases, organized bands of Sikhs were responsible for atrocities.
The late Harkishan Singh Surjeet, of the Communist Party of India (Marxist), witnessed the events and claimed in an interview: 'The communal attacks on the minorities were definitely planned.
I know more about the persons involved in the eastern wing because I was there.
I saw those dreadful acts with my own eyes.
In that conspiracy, the Maharaja of Patiala was involved.
The idea was that if the Muslims were driven out.' The attacks on Sikhs and Hindus in March 1947 in Rawalpindi are regarded as one of the major crimes that triggered off others.
Nehru believed the Maharaja had sought to ethnically cleanse the territory of Muslims as part of this effort.
Maharajas of Patiala and Faridkot, and Yadavindra Singh is quoted as having said "We won't leave a Muslim here" at a party with British officers.
The Foreign Minister of Patiala, Sardar Bari Ram Sharma issued a denial stating "I definitely assert that no Patiala soldier has associated himself with or has been involved in any killings in any part of the East Punjab."

He agreed to the incorporation of the princely state into India on 5 May 1948.

In 1956, Sir Yadavindra Singh donated the Anand Bhawan, a 150 bigha palace, to the Government of Punjab (before the creation of Himachal) for a holiday home for poor children, which was later leased out to Baba Ramdev for his Patanjali Trust.
He founded Yadavindra Public School.
Lal Bagh Palace, the building in which Yadavindra Public School is housed was donated by Sir Yadavindra Singh.
The Yadavindra Public School, Mohali is also named after him and was established by the members of his family.
