Year 628 (DCXXVIII) was a leap year starting on Friday (link will display the full calendar) of the Julian calendar. The denomination 628 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.


By place

Byzantine Empire

  • Spring – Byzantine–Sassanid War: Emperor Heraclius issues an ultimatum for peace to King Khosrow II, but he refuses his generous terms. The war-weary Persians revolt against Khosrow's regime at Ctesiphon, and install his son Kavadh II on the throne on February 25. He puts his father to death and begins negotiations with Heraclius. Kavadh is forced to return all the territories conquered during the war. The Persians must give up all of the trophies they have captured, including the relic of the True Cross. Evidently there is also a large financial indemnity. Having accepted a peace agreement on his own terms, Heraclius returns in triumph to Constantinople.[1]
  • Third Perso-Turkic War: The Western Göktürks, under their leader Tong Yabghu Qaghan, plunder Tbilisi (modern Georgia). The Persian defenders are executed or mutilated; Tong Yabghu appoints governors (tuduns) to manage various tribes under his overlordship.[2]
