__NOTOC__
Year '''324''' ('''[[Roman numerals|CCCXXIV]]''') was a [[leap year starting on Wednesday]] (link will display the full calendar) of the [[Julian calendar]]. At the time, it was known as the '''Year of the Consulship of Crispus and Constantinus''' (or, less frequently, '''year 1077 ''[[Ab urbe condita]]'''''). The denomination 324 for this year has been used since the early medieval period, when the [[Anno Domini]] [[calendar era]] became the prevalent method in Europe for naming years.

* [[September 18]] – [[Battle of Chrysopolis]]: Constantine I definitively defeats Licinius at [[Üsküdar|Chrysopolis]], and becomes sole Emperor, thus ending the period of the [[Tetrarchy]]. Licinius escapes and gathered around 30,000 of his surviving troops at [[Nicomedia]].
* [[December 19]] – Licinius abdicates his position as Emperor. He is pardoned by Constantine I as a result of the supplication of his wife [[Flavia Julia Constantia|Constantia]] (who is Constantine's halfsister), and banished to [[Thessaloniki|Thessalonica]] as a private citizen.
