Chaudhuri of Bakla-Chandradwip, an employee of the Qanungo office. These lessees later became the Zamindars of Sandwip. Khan left more than half of the island to himself and then distributed five-eighths of the remainder to Bakhtiyar Muhammad and Muhammad Hanif and three eighths to Madhusudan Chowdhury. A portion of Sandwip, Sholo Anna was jointly owned to meet various expenses. Part of the sub-contracted lessees later became known as Dihi Musapur, Dihi Bakharpur and Dihi Rampur. Khan's headquarters was located west of the Musapur Dighi (lake) and continues to be known as Sadari Bhita although the building is no longer standing. From around 1690 to the 1730s, the zamindars of Sandwip were Chand Khan's two sons, Junud Khan and Muqim Khan, Muhammad Hanif's son Muhammad Muqim, as well as Madhusudan Chaudhuri son Janardan Chaudhuri . Being the successors of Chand Khan, Junud Khan and Muqim Khan generally dominated rule over the island. In the next period, the prominent landowners of the island were Muhammad Raja (son of Junud Khan), Muhammad Husayn (son of Muqim Khan), Bakhar Muhammad and Zafar Muhammad (sons of Muhammad Muqim) and Ramchandra Chaudhuri (son of Janardan Chowdhury). Bakharpur was named after Bakhar Muhammad's zamindari. Muhammad Husayn died in 1743. The next zamindars of Sandwip were Chowdhury Abu Torab Khan, Muhammad Murad, Muhammad Ibrahim, Muhammad Wasim, Muhammad Akbar and Surya Narayan Chowdhury. From 1750 to 1763, Abu Torab overpowered the other zamindars and dominated the island under a single authority. Ghoshal, the founder of Khidrpur's Ghoshal dynasty and the clerk of Harry Verelst, the first British governor of Chittagong, suggested that Verelst colonise Sandwip in 1763 and replace the Mughal wadadar Ozakur Mal with him. One of Verelst's employees Vishnucharan Basu took the role as the first Wadadar in British Sandwip. Ram Kishore Badujej was appointed as Basu's deputy. Abu Torab could not accept Ghoshal's authority and fought against it, but was ultimately defeated. The volume of shipbuilding in Sandwip increased extensively during the Mughal period. In the 17th century, the shipyards of Sandwip were used to build warships for the Ottoman caliphs. In the late 18th century to early 19th century, Armenian merchants began to do business on the island. Khojah Kaworke, Khojah Michael and Agha Barshick owned several salt farms in Sandwip, and the existence of salt factories were noted by Italian traveller Niccolao Manucci.
