İbrahim of Menteşe

İbrahim Bey was the fourth ruler of the Menteşeid beylik of southwestern Anatolia, succeeding his father Orhan Bey. After a crusader fleet took İzmir from Aydın in 1344, the Menteşeids joined Aydın in attacking Crete.

As İbrahim prepared in 1350 to march on İzmir, Venice threatened the harbour and compelled him to sign a treaty disarming the beylik. He died around 1355, and his lands passed to his sons Musa, Mehmet and Ahmet.
