Anatolian beyliks
Ephesians were incorporated as vassals into the Ottoman Empire for the first time in 1390. The Central Asian warlord Tamerlane defeated the Ottomans in Anatolia in 1402, and the Ottoman sultan Bayezid I died in captivity. The region was restored to the Anatolian beyliks. After a period of unrest, the region was again incorporated into the Ottoman Empire in 1425.
