Calcutta (or Kolkata as it is now called) is the capital of the Indian state of West Bengal. It is located in eastern India on the east bank of the River Hooghly. The city is a colonial city developed by the British East India Company and then the British Empire. The city was the capital of the British Indian empire till 1911 when the capital was relocated to Delhi. Kolkata witnessed a fast rise as the second city of the British Empire in the 1800s accompanied by the development of a culture that was a coalescence of European philosophy with Indian tradition. The city is also noted for its revolutionary history, ranging from Indian struggle for independence to the leftist Naxalite and trade union movements. Labelled the "Cultural Capital of India", "The City of Processions", "The City ...more >>of Palaces", and the "City of Joy", Kolkata has also been home to luminaries such as Rabindranath Tagore, Subhash Chandra Bose, Mother Teresa and Satyajit Ray. Problems related to rapid urbanisation started to plague the city from 1930s and still the city is an example of an urban hotbed of the developing nations.
