Kolkata (Calcutta) is third most populated city in India, with a
population of around 5 million. In 2001, the city's name was officially changed
from Calcutta to Kolkata. The city is now eastern India's centre of business,
commerce and finance.
Kolkata is home to five Nobel laureates – Ronald Ross, Rabindranath Tagore, Mother Teresa,
CV Raman and Amartya Sen.
Kolkata is not as old as other Indian cities, like Delhi;
it's almost entirely a British creation and was the capital of British India
until 1912.
