The Battle of Yarmouk in 636 CE between the Byzantine Empire and the Rashidun Caliphate saw the empire experience another humiliating defeat. [10] This further led to competition between Venice, and Genoa to get emperors on the throne who supported their respective trade agenda to the detriment of the other, adding another level of instability to the Byzantine political process.[10]. [12] The loss of control over its own revenue sources drastically weakened the Byzantine empire, hastening its decline. The most significant events generally agreed by historians to have played a role in the decline of the Byzantine empire are summarised below: The collapse of imperial power and authority after 1185 revealed the inadequacy of this approach. Byzantines were Greeks in the reality. Under this arrangement, which was in its heyday from circa 650 to 1025, the empire was divided into several regions which contributed locally raised troops to the imperial armies. Manuel I Komnenos, for example, was able to muster an army of over 40,000 men. The result was a weakening of the Byzantine defenses in the region, which, when combined with insufficient resources and incompetent leadership, led to the complete loss of all the empire's Asian territory to the Turks by 1338. The damage to Byzantium was incalculable; many historians point to this moment as a fatal blow in the empire's history. The Byzantine Empire fell, and Islam spread into Eastern Europe. Second, the Byzantine Empire was weakened politically because the Monophysite Christians were not loyal to its spiritual and political leaders. The Byzantine Empire experienced several cycles of growth and decay over the course of nearly a thousand years, including major losses during the Arab conquests of the 7th century. Much of the Nicaean Emperors' efforts now went into combating the Latins, and even after Constantinople was returned to Greek rule under the Palaiologoi in 1261, the Empire exerted much of its efforts into defeating its Latin neighbours, contributing to the eventual failure of the Crusades by 1291. This was true already during the Third Crusade, which induced emperor Isaac II Angelos to make a secret alliance with Saladin to impede the progress of Frederick Barbarossa, but open conflict between Crusaders and Byzantium erupted in the Fourth Crusade, resulting in the Sack of Constantinople in 1204. One of the chief anti-unionist leaders was Michael's own sister Eulogia (aka Irene), who fled to the court of her daughter Maria Palaiologina Kantakouzene, Tsarina of the Bulgars, from where she intrigued unsuccessfully against Michael. The century also saw the invasion of the Normans who had captured vast territories in Italy by the 12th century. The final fall of the Byzantine Empire was caused by attacks from the Ottomans.

Michael at first responded with comparative leniency, hoping to win the anti-unionists through persuasion, but eventually the virulence of the protests led him to resort to force. Constantinople was now itself a Crusader state, known as the Latin Empire in historiography, but from the Greek perspective as Frankokratia or "rule of the Franks".
