Byzantine–Ottoman wars

The Byzantine–Ottoman Wars were a series of decisive conflicts between the Ottoman Turks and the Byzantine Greeks that led to the final destruction of the Byzantine Empire and the rise of the Ottoman Empire . After the loss of Constantinople in 1204 the Byzantine Empire was left divided and in chaos; taking advantage of the situation the Sultanate of Rum began seizing territory in Western Asia Minor until the Nicaean Empire was able to repulse the Seljuk Turks against the remaining territories still under Greek rule. Eventually Constantinople was re-taken from the hated Latin Empire in 1261 by the Nicaean Empire. However the position of the Byzantine Empire in the European continent remained uncertain due to the presence of the rival kingdoms of the Despotate of Epirus , Serbia and the Second Bulgarian Empire . This, combined with the reduced power of the Sultanate of Rum (Byzantium's chief rival in Asia) led to the removal of troops from Asia Minor to maintain Byzantium's grip on Thrace . However the weakening of the Sultanate of Rum was by no means a blessing to the Empire as nobles known as ghazis began setting up their fiefdoms, at the expense of the Byzantine Empire. While many Turkish beys participated in the conquest of Byzantine and Seljuk territory, the territories under the control of one such Bey named Osman I poses the greatest threat to Nicaea and to Constantinople . By 1299 , Osman I felt assured of his position to declare himself Sultan and thereafter his territories became known as the Ottoman Empire . Within 50 years of Osman I's establishment of the Ottoman beylik, Byzantine Asia Minor had ceased to exist and by ca. 1380, Byzantine Thrace was lost to the Ottomans. By ca. 1400, the once mighty Byzantine Empire was nothing more than a collection of the Despotate of the Morea , a few Aegean islands and a strip of land in Thrace in the immediate vicinity of the Capital. The Crusade of Nicopolis in 1396, Timur 's invasion in 1402 and the final Crusade of Varna in 1444 allowed a ruined Constantinople to stave off defeat until 1453 . With the conclusion of the war Ottoman supremacy became established in the eastern Mediterranean . Byzantium was the shield of Western Europe.

The Byzantine–Ottoman wars were a series of decisive conflicts between the Ottoman Turks and Byzantines that led to the final destruction of the Byzantine Empire and the rise of the Ottoman Empire . In 1204 the Byzantine capital of Constantinople was sacked and occupied by the Fourth Crusaders , an important moment of the Christian East–West Schism . The Byzantine Empire, already weakened by misrule , was left divided and in chaos. Taking advantage of the situation, the Seljuk Sultanate of Rum began seizing territory in Western Anatolia , until the Nicaean Empire was able to repulse the Seljuk Turks from the remaining territories still under Roman rule. The position of the Byzantine Empire in Europe remained uncertain due to the presence of the rival kingdoms of the Despotate of Epirus , Serbia and the Second Bulgarian Empire . This, combined with the reduced power of the Sultanate of Rum (Byzantium's chief rival in Asia) led to the removal of troops from Anatolia to maintain Byzantium's grip on Thrace . The weakening of the Sultanate of Rum brought no long-term advantage to the Empire, as nobles known as ghazis began setting up fiefdoms at the expense of the Byzantine Empire. While many Turkish beys participated in the conquest of Byzantine and Seljuk territory, the territories under the control of one such bey, Osman I , posed the greatest threat to Nicaea and to Constantinople . Within 90 years of Osman I's establishment of the Ottoman beylik, the Byzantines lost all their Anatolian territory and by 1380, Byzantine Thrace was also lost to the Ottomans. By 1400, the once mighty Byzantine Empire was nothing more than the Despotate of the Morea , a few Aegean islands , and a strip of land in Thrace in the immediate vicinity of the capital. The Crusade of Nicopolis in 1396, Timur 's invasion in 1402 and the final Crusade of Varna in 1444 allowed a ruined Constantinople to stave off defeat until it finally fell in 1453 . With the conclusion of the war, Ottoman supremacy in the eastern Mediterranean was established.

The Byzantines, already having been in a weak state even before the partitioning of their Empire following the 4th Crusade , failed to recover fully under the rule of the Palaiologos dynasty . Thus, the Byzantines faced increasingly disastrous defeats at the hands of the Ottomans. Ultimately, they lost Constantinople in 1453 , formally ending the conflicts (however, several Byzantine Holdouts lasted until 1479). Taking advantage of the situation, the Seljuk Sultanate of Rum began seizing territory in western Anatolia , until the Nicaean Empire was able to repulse the Seljuk Turks from the remaining territories still under Byzantine rule. The position of the Byzantine Empire in Europe remained uncertain due to the presence of the rivals in Epirus , Serbia and Bulgaria . This, combined with the declining power of the Sultanate of Rum (Byzantium's chief rival in Asia Minor) led to the removal of troops from Anatolia to maintain Byzantium's grip on Thrace . The decay of the Sultanate of Rum brought unexpected instability to the Anatolian frontier, as nobles known as ghazis began setting up fiefdoms at the expense of the Byzantine Empire.
