Tej Singh Prabhakar was the last ruling Maharaja of the princely state of Alwar, which is presently known as Alwar District in the state of Rajasthan in the northwest of India. He was a distant cousin of the preceding ruler Jai Singh Prabhakar who was exiled from the state of Alwar and was stripped of his rank, power and titles by the British Government for misconduct, cruelty and misdemeanor. Later Tej Singh was chosen by the British East India Company as the next Maharaja of Alwar.

Rule of Tej Singh Prabhakar
He was a rather popular and efficient ruler who reigned over the territory from the year 1937 to 1947, when the country gained independence from the British administration. He was knighted in the year 1943. He strongly detested the growth of the Indian National Congress Party and was much loyal to the British Government. After the murder of Mahatma Gandhi, Tej Singh Prabhakar was detained by the Delhi authorities on the controversial charges of being involved in the assassination plot. Moreover, the state of Alwar was seized by the Government of India.

In the year 1948, Alwar was merged with the princely states of Eastern Rajputana, which formed the Matsya Union. It was later merged again with the Greater Rajasthan in 1949. Sir Tej Singh Prabhakar retired to Delhi in the year 1948. Later in 1971, he stripped of his titles and styles, due to the mass de-recognisation of the royal families under the regime of Indira Gandhi.
