One event that helped start the Renaissance was the fall of the Byzantine Empire.
The siege and capture of the city by sultan Mehmet the Conqueror, in 1453. That also meant the end of the Byzantine Empire itself.
The collapse of the Western Roman Empire opened the Byzantine Empire to being attacked as well. The resources and troops were used for that, rather than being used to defeat the Persians.
The Byzantine Empire fell in 1453 C.E. when the Ottoman Turks, led by Sultan Mehmed II, captured Constantinople. This event marked the end of the Byzantine Empire, which had been a significant power in the Mediterranean for over a thousand years. The other years listed, such as 476 C.E., are associated with the fall of the Western Roman Empire, not the Byzantine Empire.
The Byzantine Empire was effectively destroyed by the Ottoman Empire, which was a rising power in the late medieval period. The pivotal event was the Fall of Constantinople in 1453, when the Ottomans, led by Sultan Mehmed II, captured the city, marking the end of the Byzantine Empire. This conquest allowed the Ottomans to expand their influence across Southeastern Europe and the Eastern Mediterranean.
The Byzantines were people of the Byzantine Empire, which was called the Roman Empire during the Middle Ages. The reason it is called Byzantine is to distinguish it from the ancient Roman Empire, the Carolingian Empire, and the Holy Roman Empire, all of which were called the Roman Empire by at least someone. The Byzantines provided a center of learning, government, and trade through the Middle Ages, until they were conquered by the Ottoman Turks, an event many call the end of the Middle Ages. There is a link below to an article on the Byzantine Empire.
In 1453, the Ottoman Empire under Mehmed II successfully captured Constantinople, the capital of the Byzantine Empire. This event marked the end of the Byzantine Empire and the beginning of Ottoman rule in the region, as well as the fall of one of the most significant cities in the medieval world.
The Battle of Manzikert is seen as the beginning of the end of Byzantine control over Asia Minor. After that, the Seljuks continued to expand into Asia Minor.
The people of the Byzantine Empire were angered when Pope Leo III crowned Charlemagne as the Holy Roman Emperor in 800 AD because they viewed this act as a direct challenge to their own authority and legitimacy. The Byzantine Empire, with its capital in Constantinople, considered itself the continuation of the Roman Empire and believed that the title of emperor should rightfully belong to the Byzantine ruler. Additionally, the crowning of a Western ruler by the pope symbolized a shift in power dynamics, undermining the Byzantine claim to be the center of Christendom. This event heightened tensions between the Eastern and Western branches of Christianity, contributing to the eventual schism.

The Ottoman Empire attacked Constantinople in 1453. Led by Sultan Mehmed II, the Ottomans laid siege to the city, which was the capital of the Byzantine Empire. After a prolonged siege, Constantinople fell on May 29, marking the end of Byzantine rule and a significant expansion of Ottoman territory. This event is often considered a pivotal moment in history, leading to the rise of the Ottoman Empire as a major power in the region.
Becuase they were weak The Greeks never had an empire. All they were globally were a collection of independent city-states. Alexander the Great tried to establish an empire but at his death it all fell apart. So there is no comparison.
