Francis Day and his superior Andrew Cogan can be considered as the founders of Madras (now Chennai). They began construction of the Fort St George on 23 April 1640 and houses for their residence. Their small fortified settlement quickly attracted other East Indian traders and as the Dutch position collapsed under hostile Indian power they also slowly joined the settlement. By the 1646, the settlement had reached 19,000 persons and with the Portuguese and Dutch populations at their forts substantially more. To further consolidate their position, the Company combined the various settlements around an expanded Fort St. George, which including its citadel also included a larger outside area surrounded by an additional wall. This area became the Fort St. George settlement. As stipulated by the Treaty signed with the Nayak, the British and other Christian Europeans were not allowed to decorate the outside of their buildings in any other color but white. As a result, over time, the area came to be known as 'White Town'.
According to the treaty, only Europeans, principally Protestant British settlers were allowed to live in this area as outside of this confine, non-Indians were not allowed to own property. However, other national groups, chiefly FrenchPortuguese, and other Catholic merchants had separate agreements with the Nayak which allowed them in turn to establish trading posts, factories, and warehouses. As the East India Company controlled the trade in the area, these non-British merchants established agreements with the Company for settling on Company land near "White Town" per agreements with the Nayak. Over time, Indians also arrived in ever greater numbers and soon, the Portuguese and other non-Protestant Christian Europeans were outnumbered. Following several outbreaks of violence by various Hindu and Muslim Indian communities against the Christian Europeans, White Town's defenses and its territorial charter was expanded to incorporate most of the area which had grown up around its walls thereby incorporating most of its Catholic European settlements. In turn they resettled the non-European merchants and their families and workers, almost entirely Muslim or of various Hindu nationalities outside of the newly expanded "White Town". This was also surrounded by a wall. To differentiate these non-European and non-Christian area from "White Town", the new settlement was termed "Black Town. Collectively, the original Fort St. George settlement, "White Town", and "Black Town" were called Madras.
