The Isfendiyarids — also called the Jandarids — controlled the Black Sea coastal region of Kastamonu and Sinop through a period of extraordinary political pressure, squeezed between the expanding Ottoman sultanate and the disruption caused by Timur's 1402 invasion of Anatolia. Isfendiyar Bey actually exploited Timur's defeat of Bayezid I at Ankara to reclaim territory the Ottomans had previously absorbed, temporarily restoring the beylik's autonomy.
Copper mangirs of this dynasty are poorly documented in the major catalogues, and attribution by ruler remains difficult where mint names are absent from the flan.
