Colonial cities in India developed under European colonial rule between the 16th and 20th centuries. Chennai, originally known as Madras, is highlighted as a case study. It began as a small trading settlement established by the British East India Company in 1639. Over centuries, the British expanded control of the area and merged surrounding villages to form the modern city of Chennai. Colonial development transformed Chennai into an important political and economic center, establishing institutions and infrastructure that supported its growth into a major city.
