This article surveys and analyses the available materials on Dato Mogul, the putative first ruler of Singora (present-day Songkhla) in the early seventeenth century. It argues that the narrative in Thailand surrounding Dato Mogul and his emergence is sketchy at best. In reviewing the literature and drawing on new and extant primary sources, we argue that Dato Mogul was likely a Malay governor authorised by Ligor. This reappraisal presents a more accurate biographical narrative and provides greater insight on polity formation in Lower Siam in the period under review.
