Shrimant Maharaja Sir Pratap Singh Rao Gaekwad (29 June 1908 – 19 July 1968), belonging to the Gaekwad dynasty of the Marathas, was the last ruling Maharaja of Baroda.
He succeeded to the throne upon the death of his grandfather Sayajirao Gaekwad III in 1939.
In 1947, India became independent of Britain, and by 1949, Baroda had been merged into the Dominion of India.
Pratapsinh retained his title and certain privileges, but he was "deposed" by the government of India in 1951 for irresponsible behavior.
He then retired to Europe with his second wife, a woman of notorious reputation, and settled in Monaco.
He died in 1968 and was succeeded by his eldest son, Fatehsinghrao Gaekwad, who had been officiating as Maharaja since 1951.
He founded the Maharaja Sayajirao University of Baroda in 1949 as per the wishes of his grandfather, Sayajirao, and settled the "Sir Sayajirao Diamond Jubilee and Memorial Trust" which still exists, and caters to the educational and other needs of the people of the former Baroda State.
