How did chinatown come about?

It all started during the 19th century when Sir Stamford Raffles concieved Chinatown. He was not satisfied with the way that the settlement around the Singapore River and Boat Quay had developed. The Singapore River and Boat Quay was very different if you were to compare the past and the present. Most of the immigrants that were living in Chinatown were from China at that time.
