Given a reference text about Former Indian Prime Minister Shri P.V Narasimha Rao, tell me when they were born, when they were Prime Minister and their most significant accomplishments in office
Shir P.V. Narsimha Rao was born 28 June 1921 and was the 9th Prime Minister of India from 1991 to 1996. His most significant accomplishment was the major shift of the Indian Economy from one governed by fiscally conservative socialistic and protectionist policies ("License Raj") to a more liberal free market enterprise with lesser regulations and protectionism.

On the demographic front, Rao's ascendancy is significant because he was the first Prime Minister from South India and the second from non-Hindi speaking region.
