Year '''109''' ('''[[Roman numerals|CIX]]''') was a [[common year starting on Monday]] of the [[Julian calendar]]. At the time, it was known as the '''Year of the Consulship of Palma and Tullus''' (or, less frequently, '''year 862 ''[[Ab urbe condita]]'''''). The denomination 109 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.
