Reddit mentions of The Alexiad (Penguin Classics)

I strongly recommend checking out Steven Runciman's History of the Crusades. The first one has Behemond I as a major actor. He is an incredibly entertaining character, and Runciman goes into great detail about him. The book itself is narrative, so it reads very easily. Though, Runciman is a little biased against the Crusaders because he is a Byzantine scholar himself. All three books in the series provide a very good historical overview of the Crusades in general, and paint a great picture of the amazing cast of characters of the time period.

On a side note, one of the funniest things with Bohemond is Anna Komnene's apparent attraction to him from her description in The Alexiad

Here's the most recent translation if you decide to give it a go.

You are p dumb and also you rely on Wikipedia for knowledge. The Roman (not Greek) emperor renamed the city after himself but to the Greek population until and after the fall of the city in 1453, thirteen centuries later, it remained Byzantium. and that was the name of their empire as a result.

I suggest that you first read John Julius Norwich's superb three-part history of the Byzantines:

https://www.amazon.co.uk/Byzantium-Early-Centuries-v/dp/0140114475
https://www.amazon.co.uk/Byzantium-v-Apogee-Apogee/dp/0140114483/
https://www.amazon.co.uk/Byzantium-Decline-John-Julius-Norwich/dp/0140114491/

Then a useful primary source to start with would be Anna Komnene's Alexiad, written about her father the Emperor and infused with first-hand knowledge of the city of Byzantium and its empire: https://www.amazon.co.uk/Alexiad-Penguin-Classics-Anna-Komnene/dp/0140455272

Then perhaps something like Procopius' Secret History. Then come back and try and tell me that you don't cringe at that time you thought the Greeks called their city "Constantinople".
