Year 474 (CDLXXIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Leo without colleague (or, less frequently, year 1227 Ab urbe condita). The denomination 474 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.
February 9 – Zeno, father of Leo II, is crowned as co-emperor (Augustus). He rules the empire together with his son, and stabilises the Eastern frontier.
November 17 – Leo II dies of an unknown disease (possibly poisoned by his mother Ariadne), after a reign of 10 months. Zeno becomes sole Eastern Emperor.[2]
Winter – Zeno sends an embassy, to conclude a peace with King Genseric. He succeeds in an agreement with the Vandals, to secure the commercial routes in the Mediterranean.

As corroboration for 18 January, Cyril of Scythopolis notes that Euthymius died on 20 January 473 and that the emperor Leo I died 'at the end of the first year after the death of the great Euthymius'.
