Mehmed I
After Musa’s defeat by Ottoman sultan Mehmed I in 1413, Bedreddin was exiled to Iznik, and his followers were dispossessed of their timars. However, he soon decided to capitalize on the climate of opposition to Mehmed I following the disorder of the still-fresh interregnum. Leaving his exile in Iznik in 1415, Bedreddin made his way to Sinop and from there across the Black Sea to Wallachia. In 1416, he raised the standard of revolt against the Ottoman state.
