Siege of Constantinople

Date: June 29, 626 • Location: Beyoğlu, Turkey

This milestone marked the outbreak and beginning of this historic period, which spanned 626.

The Avars and Sassanids besiege Constantinople, held by Byzantine troops under Patrician Bonus.

The Pannonian Avars or Carpathian Avars were a confederation of Eurasian nomads. They were also known as the Obri in the chronicles of the Rus, as the Abaroi or Varchonitai, or Pseudo-Avars in Byzantine sources, and as the Apar to the Göktürks. They established the Avar Khaganate, centred in the Carpathian Basin, which lasted from the late-6th to the early-9th centuries CE. They exerted influence and control over surrounding areas in Central, Eastern and Southeastern Europe.
