Year 422 (CDXXII) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Honorius and Theodosius (or, less frequently, year 1175 Ab urbe condita). The denomination 422 for this year has been used since the early medieval period, when the Anno Dominicalendar era became the prevalent method in Europe for naming years.
March 3 – Theodosius II issues a law to form provisions in peacetime. He instructs landowners leasing towers in the Theodosian Walls to assist with the build-up of emergency goods. Theodosius pays an annual tribute of 350 pounds of gold to the Huns in order to buy peace.[1]
Theodosius II receives a statue at Hebdomon, military parade ground on the shores of the Propontis, just outside Constantinople. On its base (fragments are now in the Istanbul Archaeology Museum), an inscription praises him as “everywhere and forever victorious.”
