Timeline

1. c. 1380–1410Korean Peninsula · Korean PeninsulaFrom the late Goryeo period to the early Joseon founding, the Korean Peninsula introduced powder arrow and sinijeon technology through Yuan-Ming exchanges, and the military began equipping arrows capable of firing powder warheads, laying the gunpowder and arrow foundation for later multi-barrel volley devices.
2. 1431Hanseong · HanseongDuring King Sejong's reign, the Office of Firearms was overhauled and firearms production expanded; the military experimented with fixing multiple powder arrows onto wooden frames or wheeled carts for concentrated firing.
