An opportunity to further the mapping of An opportunity to further the mapping of trade routes, as trade routes are regarded trade routes, as trade routes are regarded as critical to the spread of Islamas critical to the spread of Islam

Points, Polygons, and Points, Polygons, and UncertaintyUncertainty
Secondary sources use spatial shorthand, including citing a city for an area that may be larger than a city alone, or only a few individuals within that city
Secondary sources may cite a contemporary geographic name that may or may not represent the same spatial unit in different understandings (i. e. “trade with China”)
Evidence and UncertaintyEvidence and Uncertainty
Early period: extreme uncertaintyArtifacts: graves in central Java with Islamic inscriptions
Chronicles: Ma-Huan, traveling with Zheng He to passisir coast, north Java
Later: clearer indications, such as rulers inviting Islamic scholars from middle East to teach, and presence of Islamic manuscripts
Points, Polygons, and Points, Polygons, and UncertaintyUncertainty

These chronicles have information relevant to trade with These chronicles have information relevant to trade with Indonesia, but are compiled outside IndonesiaIndonesia, but are compiled outside Indonesia
Points, Polygons, and Points, Polygons, and UncertaintyUncertainty
At worst:
Important cultural and political entities that leave little record
Example: Srivijaya, a major trading entrepot, site of large monasteries, exporter of culture that left its mark in inscription and art objects across western Indonesia, Malaysia, and peninsular Thailand
Capital possibly near Palembang in Sumatra
Likely to have been built of largely perishable materials, perhaps much of it over water, so little survives
