Year 623 (DCXXIII) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. The denomination 623 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.


Byzantine Empire

  • Byzantine–Sassanid War: Emperor Heraclius invades Armenia, leaving his son Constantine (age 11) and co-regent Bonus to defend Constantinople against the Persians still at Chalcedon (modern Turkey). He sails with 5,000 reinforcements to join the Byzantine army at Trapezus. Raising additional forces in Pontus, Heraclius strikes through the mountains of Armenia and the northern sub-Caucasian principalities. He plunders Media (Azerbaijan), and avoids the Persian armies who attempt to trap him.
  • Europe

  • King Clothar II gives Austrasia to his son Dagobert I, age 20, effectively granting the kingdom semi-autonomy in repayment for the support of its nobles, most notably Pepin of Landen (Mayor of the Palace), and in recognition of calls from the Austrasians for a king of their own. Arnulf, bishop of Metz, becomes advisor to Dagobert.
  • Samo, reputedly a Frankish merchant, is elected king of the Slavs in Moravia, Slovakia and Lower Austria. A string of victories over the Avars proves his utilitas (usefulness) to his subjects, and he secures the throne to establish his own kingdom, which stretch from the upper Elbe to the Danube.
