What peoples invaded the territory of Byzantium after the death of Justinian?

Emperor Justinian died around 565 AD. After his death, the Slavs invaded the European part of Byzantium, and a little later, in the 7th century AD, Arabs from the south and Bulgarians from the north. In 681, the Bulgarian Khan Asparukh founded the Bulgarian state in the Balkans (in 1981 they celebrated the 1300th anniversary), and at the beginning of the VIII century the advance of the Arabs was stopped. In 1071 the Turks invaded from the east and defeated the Byzantine army in a battle near the city of Manzikert.
