"The History of Sulu" by Najeeb M. Saleeby is a historical account written in the early 20th century. The work primarily focuses on the Sulu Archipelago, tracing its geographical features, genealogy, and significant historical events from prehistoric times to the Spanish conquest, examining the rise of the Sulu sultanate and its interactions with foreign powers. At the start of the narrative, the author discusses the aim of his research, which was to uncover notable historical events predating Spanish colonization and to explore the origins of the Sulu Archipelago's inhabitants. Saleeby highlights the difficulties he faced in gathering authentic genealogical records and historical data from local leaders, ultimately sourcing a manuscript detailing the genealogy of Sulu which formed a significant basis for his work. The opening chapters lay out the geographical description of the islands, setting the stage for a deeper understanding of the social and political dynamics of the region and its rich history, as well as the connections to broader Malayan history.
