Heraclius - Byzantine emperor

Heraclius

After the death of Justinian in 565 AD, Justin II became the next Roman Emperor. But Justin and his successors could not hold the great empire Justinian had reassembled. It was too expensive to pay for all those soldiers and ships.

In 568 AD, the Lombards invaded Italy and took half of it away from Rome. By 620 AD, the Visigoths had pushed the Romans out of Spain as well. The Romans were always at war with the Sassanids in West Asia, and that was so expensive that there was not enough money left over to keep control of the Western Mediterranean.

Then during the reigns of the emperors Tiberius II and Maurice, the Avars and Slavs invaded Greece across the Danube. In 591 AD, Maurice managed to push the Sassanids back enough to stop fighting them and go fight the Slavs for a while. But he cut the pay of the soldiers, and also tried to make them spend the winter north of the Danube, where it was cold and unpleasant. In 602 they revolted, killed Maurice and his family, and named a new emperor, Phocas (FOE-kass).

Phocas turned out to be a terrible choice for emperor, suspicious and cruel (like Domitian) and also King Khusro (KUSS-row) of the Sassanids used the murder of Maurice as an excuse to invade the Roman Empire again, where he took over all of Syria, Lebanon, Jordan, Israel, and Egypt, all the way to the Mediterranean coast. The Sassanids sacked Jerusalem and killed the people who lived there (this was widely blamed on Jewish treachery). By 610 AD Phocas was killed and a general from Africa, Heraclius (her-AK-lee-us), became emperor.

It took Heraclius a long time to fix things up, and it was very expensive. First he made a treaty with the Avars, and then in 622 he melted down all the gold of the churches in Constantinople to pay for a massive attack against the Sassanids. The attack was successful. The Sassanids finally murdered their king Khusro, and the new king made peace with the Romans in 628.

But the Roman empire was exhausted by this massive effort, and when the Arabs invaded Syria and Iraq in 633 AD, Heraclius could not defend it. By the time Heraclius died in 641, most of the south-eastern Mediterranean was in Arab hands. He left the empire to his sons, but they were not able to fight off the Arabs either.
