Bayezid I
Bayezid I was sultan of the Ottoman Empire.
History
Bayezid I was born the son of Murad I.
Murad was killed in the Battle of Kosovo, leaving Bayezid to succeed and complete the conquest of Serbia. He further conquered Bulgaria, beseiged Constantinople, and attempted to invade Hungary. While the last was not successful, he was able to rebuff the Crusade of Nicopolis.
A tentative peace had formed in the balance of powers surrounding the lands of the former Sultanate of Rum. For example, the beylik of Dulkadir emerged in the 14th century power vacuum left by the short-lived Eretnid sultanate. Qaraja vassalized the state to the Mamluks in 1337. His younger son Suli rebelled against the suzerainty and allied with Timur. The Mamluks had Suli assassinated in 1395 and installed his son Sadaqa. Shortly thereafter Bayezid intervened, this time installing Sadaqa's cousin Mehmed.
Bayezid conquered the beyliks of Karaman and Djanik (alt. Canik) in 1399, disrupting this peace, so Timur then declared war against both the Ottomans and the Mamluks. In the Battle of Ankara in 1402, the Ottomans were defeated and Bayezid was captured. He died in captivity the next year, triggering the Ottoman Interregnum.
