Note 734 — APPENDIX B THE EMIRATES OF ASIA MINOR DURING THE FOURTEENTH CENTURY
Reading edition
Muralt, in the bibliography of his Chronographie Byzantine, puts Ibn Batutah at 1320. There can be no doubt about this being an error, for when Ibn Batutah visited the Ottoman domains, Orkhan was ruling, and Nicaea had been captured. I put 1340 as latter limit, because Ibn Batutah speaks of some places captured by Orkhan before 1340 as being still independent.
