Bhati was a large region of medieval Bengal, referred to by Abu'l-Fazl ibn Mubarak and by others until at least the 17th-century CE, during the period of the Mughal Empire. It was said to encompass the river delta area now lying within the borders of Bangladesh and often referred to as eastern Bengal. The area of Bhati supposedly included the low-lying areas of the greater districts of Dhaka, Mymensingh, Tippera (Comilla) and Sylhet in the days of Akbar and Jahangir, extending perhaps all the way to Sylhet.. However Abu’l Fazl in the Akbarnama seems to suggest that Bhati was in fact larger than Bengal itself and extended to Bihar. The fact that this conflicts and overlaps with virtually all of Bengal suggests that the Mughals had no clear idea of what the region of Bhati entailed, it was likely much smaller than claimed, and furthermore, not a cohesive region at all. In Bengali, the word refers to low lying lands downstream of any given river rather than a specific region, and thus would have, as it still does, referred to small pockets of land scattered throughout Bengal rather than a true region on its own.
