1.1.a) HISTORY OF KOLKATA It is interesting to explore the origin & history of kolkata, the capital of British India. Calcutta history is not that old as that of Delhi. Calcutta, the city of joy was established in the year 1686, as a result of the expansion plans of the British Raj. It was during those times that European powers were heading their way towards capturing the small villages of Sutanati, Govindpur, and Kalikata. Calcutta derived its name from the last of the village settlements of kalikata.The city kept progressing until 1756, when Siraj-Ud-Daula (Nawab of Bengal) attacked and succeeded in driving the British away from the town. It was during that time that most of the British civilians had escaped, but a few of them were captured and imprisoned in a suffocating room. This incident has become a history in itself and was given the name 'Black hole tragedy'. In 1757, the following year, Battle of Plassey took place, in which Robert Clive took over the city by defeating the NawabThe end of battle witnessed the establishment of Supreme Court in 1774,
