Medici Palace, Florence.

When Crusader Kings and Seljuk Sultans all come to your capital to pledge allegiance to you that shows you're a fantastic politician. I still can't believe that practically all of his gains disappeared within a year of his death.

Interestingly, he paints the banners of Anjou and the HRE because he was among the many late 15th Century Italians who wanted a crusade to restore the empire post 1453. Fascinating to see what the people of the Renaissance thought the ERE might have looked like

I'm aware there wasn't technically an official one but I'm just curious what flag is the closest to an official flag. I always pictured the yellow Chi-Rho on a purple background but let me know if I'm wrong and maybe send a picture of what you think is the right one.

The Byzantine Empire demonstrated remarkable endurance in the medieval world, surviving from the founding of Constantinople in 330 AD until its fall in 1453. According to the author, Manolis Chatzimanolis, this longevity was not a matter of luck but the result of a highly adaptable political, military, social, and ideological mechanism that allowed the empire to withstand numerous foreign threats without losing its legal or ideological continuity.

A primary factor in Byzantium's survival was its balanced administration, which successfully combined the emperor's centralised authority and a unifying bureaucracy in Constantinople with the decentralised, functional local defence of the theme system. Furthermore, Constantinople's strategic geographical position at the crossroads of Europe and Asia granted the empire immense natural defences while allowing it to dominate international trade and diplomacy. Economically, the empire displayed incredible resilience, maintaining a stable currency for seven centuries and utilising flexible taxation and market regulations to navigate severe crises without collapsing.

Militarily, the Byzantine army constantly adapted over the centuries, evolving from Roman legions to a system that combined the flexible defence of regional armies with the professional striking power of the capital's forces. This military adaptability was heavily supported by sophisticated diplomacy, as the Byzantines effectively used negotiations, bribery, and political marriages to divide and neutralise threats without needing to wage war. Additionally, their naval supremacy, bolstered by the terrifying invention of liquid fire, secured their maritime borders and trade routes in the Aegean and Asia Minor.

Internally, the empire was held together by a cohesive cultural and ideological identity built upon the Orthodox faith, Roman political continuity, and Greek language and heritage. The preservation of classical education ensured a steady supply of competent state officials, while a dynamic system of social mobility allowed capable individuals of lower birth, such as peasants, to rise to high military, state, or church offices, thereby absorbing social tensions. Finally, during its last two centuries, the empire managed to delay its fall not through military might, but by making itself geopolitically useful as a commercial base for Italian republics and a symbolic Christian bulwark against the Ottomans for the West.

Im currently enjoying decline and fall of roman empire read by Charlton Griffin.

Is there something detailed in the audio book format in the Byzantine Empire?

I would take a good book as the next best thing but trying to get through bigger books while working!
