Among the minor crops of Bangladesh, the sugar crop is significant. Among them, date palm juice is deeply intertwined with the country's culture and traditions. Date molasses made from it occupies an important place in the micro-level market system, though it has not caught the attention of all nationally. Therefore, since Saroganj is Bangladesh's largest and oldest date molasses market, this study looks at its history. Researchers have also looked into how it became a local-regional sustainable economic hub and its nature and traits. In addition to historical research methods, techniques like oral history interviews, interviews with key informants, and sustained observation have been used to meet the research goals. The research results show that a ganj called Maharajaganj was established here in the late eighteenth century and was changed to Sarojganj in the second decade of the twentieth century. Moreover, since then, seasonal date molasses hat has started to be established here. Within a hundred years, this hat became a mixed hub where some characteristics of financial, trade, and industrial hubs exist. It is expected that if the existing problems-the lack of planting date trees and decreasing the production of date juice, and the production of adulterated molasses-are solved, this hat can play a more effective and sustainable role in improving the quality of life of the people in the area in the coming days. At the same time, a small crop sector that has been ignored can help Bangladesh's economy grow in a big way at the micro level.
