Great Song chemical incendiary manuals circulate
Song military writers compiled the Wujing Zongyao and related texts with recipes for gunpowder mixtures, fire arrows, and flamethrowers. The manuals represent the earliest detailed gunpowder literature anywhere and mark the transition from alchemical curiosity to battlefield practice. The formulas described varying ratios of saltpeter, sulfur, and charcoal for different effects, from smoke screens to incendiary projectiles to crude explosive bombs.
Haakon IV crowned King of Norway
The bastard-born claimant ended a long civil war and received the Norwegian crown in Bergen from a papal legate. His court of skalds and saga-writers preserved Old Norse literature; Iceland would submit to his successors within a generation. Haakon's ambition extended Norway's reach to its greatest territorial extent, encompassing Iceland, Greenland, and the Faroes under a single Scandinavian crown.
Baiju campaigns in Anatolia
The Mongol general Baiju Noyan consolidated control over the former Seljuk lands of Anatolia, installing compliant sultans and collecting tribute. His marches terrified the Armenian kingdom of Cilicia into a permanent alliance with the Mongols that would last decades. Baiju's presence in Anatolia also disrupted trade routes, forcing Italian merchants to seek alternative paths eastward through the ports of Trebizond and Tana.
Song engineers develop the fire lance
Chinese military workshops refined the fire lance, a gunpowder-charged bamboo tube that spewed flame and shrapnel at close range. Deployed by Song infantry against Mongol cavalry, it was the ancestor of all firearms, a crude weapon whose descendants would reshape every civilization on earth. Later versions added projectiles to the tube, creating a proto-gun that would evolve into the cannon within a century.
