Ottoman Triumvirate

The Ottoman Triumvirate was not really a triumvirate in the same meaning as the Roman Triumvirates, but a period in the beginning of the 15th century when chaos reigned in the Ottoman Empire following the defeat of sultan Beyazid I in 1402 by the Mongol warlord Timur Lenk. Around 1410 the three sons of Beyazid left alive after the Battle of Ankara[?] ruled each half of the remaindants of the empire. The eldest son, Suleiman Çelebi, ruled nothern Greece, Bulgaria and Thrace. His brother, İsa Çelebi ruled Greece and the westermost of Anatolia, however he was overthrown by the younger half-brother Mehmed from his capitol in Bursa in 1404. Suleiman then accuired southern Greece as well and Mehmet ruled over Anatolia. Mehmet then sent his younger brother Mûsa across the Black Sea with a large army to conquer Suleiman. Mûsa won in Bulgaria in 1410 and Suleiman was forced to retreat south to Greece and Mûsa proclaimed himself as sultan of the Ottoman Empire. Mehmed became furious and sent small army over to Gallipoli where it was defeated. Mehmed later came to his senses and forced an allians with the Byzantine Empire. Three years later Mehmed sent over a new army. This time it was much stronger and defeated Mûsa in Kamerlu, Serbia. It was then easy for Mehmed I to overthrow his last brother in Greece and become the Ottoman sultan.
