The events around the demise of the Exarchate of Ravenna only involved the Venetians marginally. It is nevertheless important to the history of Venice.

Who were the first doges of Venice, and when and why did the Venetians decide to chose their own leaders? TL;DR It wasn't as we've been told it was.

The Venetians fleeing the Lombards migrated into the lagoons along the Adriatic coast. Lagoons in the plural, as there were several, but what kind of environment was that, why was it there, and how did the Venetian settle in?

The invasion of the Lombards in 568 set in motion another migration. A part of the people of the Byzantine province of Venetia fled the Lombards, and headed for the areas which remained under the control of Constantinople.

The Lombard invasion of Byzantine Italy in 568 was a pivotal event in Venetian history, as it kicked off the movement towards a distinct Venetian society, culture and, ultimately, state.

The principal primary sources for the earliest period of Venice are not many, but their history is rather messy.

A letter to the people of the lagoons from the Ostrogoth government, from 537.

A short episode on sewage, faeces, pits, tubes, and that kind of sh*t.

Pigs and bulls lose in the alleyways, wooden castles smashed with maces, human towers and funambulists. The Venetian carnival was quite unlike the modern replica.

A tale of pirates, maidens, box-makers, oranges, and ancient promises being kept for centuries, but others not so much.
