Chinese Gunpowder Weapons System

Timeline

1. 1000–1250Kaifeng and Lin'an armament workshops · Song dynastiesFrom the Northern Song through the early Southern Song, court armament agencies systematically compounded gunpowder, developing rockets, fireballs, caltrop fireballs, and early tube-shaped firearms, establishing basic craft standards for formula ratios, charges, and fuses.
2. 1251–1260Xiangyang-Fancheng and Diaoyu Fortress · Southern SongIn the 1250s, as Mongol forces besieged Xiangyang, Fancheng, and Sichuan fortresses, Southern Song defenders made extensive use of thunderclap bombs, heaven-shaking thunder, fire lances, and fire-oil pumps to slow the siege; in the 1259 Battle of Diaoyu Fortress, firearms coordinated with ballistae became a key component of the city defense system.
3. 1260–1300Dadu and provincial arsenals · YuanAfter acceding to the throne, Kublai Khan integrated craftsmen from the former Jin and Song states and gunners from the Western Regions, incorporating firearms into the standing armament of the Yuan army, laying the foundation for later western campaigns and their spread in East Asia, marking the upgrade of gunpowder weapons from a regional technology to an imperial military system.
