The introduction of gunpowder-based weapon in Nusantara archipelago can be traced back from Mongol invasion of Java (1293), where the Chinese-Mongol troops used cannon ("pao") against the forces of Kediri in Daha. Between 14th-15th century, numerous local sources mentioned about bedil (gun or gunpowder-based weapon), but since this is a broad term it is difficult to discern what type of weapon used in a passage. A small hand-gun dated from the year 1340 thought to be Chinese was found in Java, but the dating may have been wrong.
