Directory

317 CE

Emperor Constantine the Great and co-emperor Licinius elevate their sons Crispus, Constantine II and Licinius II to Caesars. After this arrangement Constantine rules the dioceses Pannonia and Macedonia, and establishes his residence at Sirmium, from where he prepares a campaign against the Goths and Sarmatians. Sixteen Kingdoms: Jingwen (later Yuan of Jin) flees with remnants of the Jin court and noble families to the south. He succeeds Emperor Min of Jin as first ruler of the Eastern Jin Dynasty and decides to make Jiankang (modern Nanjing) his new capital. The earliest historically verified reference to tea is recorded, although the Chinese have been drinking the beverage for centuries.
