What are the reasons for the fall of Byzantium?

The fall of Byzantium lies in the combination of several factors. The most important role in the collapse of Byzantium was played by internal problems in the empire. The decline of the peasant economy, foreign interference in the affairs of the state, which led to the general impoverishment of the country’s economy, the extinction of its dominance in the seas. The great misfortune of Byzantium was also that the empire did not have reliable and strong allies. But there were more than enough enemies, and everyone had tremendous influence in the world. It is impossible to say why exactly the empire collapsed, you can only analyze the factors that took place.
