Le Corbusier's largest and most ambitious project was the design of Chandigarh, the capital city of the Punjab and Haryana States of India, created after India received independence in 1947. Le Corbusier was contacted in 1950 by Indian Prime Minister Jawaharlal Nehru, and invited to propose a project. An American architect, Albert Mayer, had made a plan in 1947 for a city of 150,000 inhabitants, but the Indian government wanted a grander and more monumental city. Corbusier worked on the plan with two British specialists in urban design and tropical climate architecture, Maxwell Fry and Jane Drew, and with his cousin, Pierre Jeanneret, who moved to India and supervised the construction until his death.
