Byzantine in the period of emperor Herakleios (610-641)

Herakleios, the son of the Carthage Exorcist Herakleios, revolted against the oppression regime of Emperor Phokas (602-610). Herakleios, who came to Constantinople on October 3, 610 at the beginning of a fleet of North African troops, with the sup-port of the state of Egypt, sat on the Byzantine throne. When the emperor Heraclius appeared on the Byzantine throne, the state was suffering. In fact, these problems af-ter the reign of Justinian I (527-565) were even worse because of his successors. Emperor Herakleios began his work with radical reforms to stop the evil and restore the state. He corrected his economy through the church. Then he turned to the army, the most important thing for the state. For this purpose, the "thema"(military province) system was established on Anatolian soil. After establishing the Thema army, Herakleios first went to the Sassanids and, in 625, with the support of the Khazars, from Armenia to Syria. In 626, the Avars appeared in front of the walls of Constanti-nople. But these two threats, which were important for Byzantium, were defeated by Heraclesonia, on the one hand by Patriarch Sergios and the people. When the war ended in 628, the empire was completely free from the threat of Sasanid and Avar; but this peaceful circuit was short-lived. Islamic conquests that began very little later and changed the course of all history erased the achievements of the Byzantine Empire in the east. Herakleios died during the struggle against the Islamic armies in 641 AD. Heraclius death was followed by a short family conflict. Finally, the grandson II. Constance (641-668) prevailed.
