Khalifa Bayezid I Yildirim (c. 1360 - 7 February, 1411)
Born: Bursa, Anatolia
Died: Sinope, Anatolia
Reign: 1389-1411
There is no contemporary evidence of the life of the first Ottoman caliph until a series of coins issued five months after the death of his father, Murad, at the Battle of Kosovo. Popular legend indicates that he seized the throne through fraticide, but there is only evidence that his brother, Yakub, died at Kosovo or shortly thereafter. Given later history, in which Bayezid had his third wife and five of his sons executed, the legend certainly appears to fit his character.
Bayezid spent the early part of his reign consolidating a vast Balkan territory. Venetian advances in Greece and Hungarian influence in Wallachia and Bulgaria compelled the blockade of Constantinople (1391-98), the conquest of Thessaloniki (1394) and the invasion of Hungary (1395). Despite Frankish support, the Byzantine Empire was reduced to the city of Constantinople and its environs by mid-1405. Venice's forces was forced to retreat to the island fortress of Corfu and to the city of Athens.
Having defended the western provinces, Bayezid turned his attention to development of a centralised state. Primarily, this required a strengthening of control over the Turkish rulers of Anatolia; many of them would be annexed outright, but two beyliks, Karaman and Dulkadir, managed to retain some level of autonomy. Nonetheless, these efforts brought him into conflict with the conqueror Timur. Fortunately for the Ottomans, Timur's death in June 1401 led to the disintegration of his empire and, instead of defending his realm against invasion, Bayezid was able to extend Ottoman control as far east as the cities of Van and Erzurum.
In the latter years of his reign, Bayezid turned his attention to the enemies of his father. The Knights Hospitaller were expelled from Rhodes, with Philibert de Naillac surrendering the island and his title of Grand Master in May 1405. A rebellion by Serbian vassals (1404-07) provided the excuse necessary to end the Despotate's nominal independence. However, it was this conflict which led to a division within the family of the new Khalifa, a title Bayezid claimed, despite Mamluk protests, in 1405.
One of Bayezid's wives and mother to four of his children was also the sister of the deposed Despot Stefan Lazarevic. While records are scant, it appears as though one of her children, Musa, conspired with her to depose Bayezid himself after his uncle was executed for his disloyalty. The failure of the plot led to the death of Musa, his mother and his three brothers in May, 1407.
Bayezid I Yildirim died in February, 1411, was repressing a peasant revolt near Sinope in northern Anatolia. He had been born as a bey of Rum, but Bayezid left this life as Sultan of the Ottomans and Caliph of Islam. He left his throne to a twelve-year-old minor, Yusef, but initially power would rest with a new Valide Sultan, Nafise, daughter of the late bey of Karaman.
