Origins & rise

The Candar dynasty (Candaroğulları), often called the Isfendiyarids after its most famous ruler, was an Oghuz Turkmen house of the Kayı branch established in Paphlagonia, the mountainous Black Sea region of northern Anatolia. Its founder, Şemseddin Yaman Candar, had been a commander in Seljuk service; around 1291 he was granted the district of Eflani as an iqta — according to Turkish scholarship, by the Ilkhanid ruler Gaykhatu — as Mongol authority replaced the collapsing Sultanate of Rum. His son Süleyman I (r. 1309–c. 1339/41) transformed this modest appanage into a real principality, conquering Kastamonu and Safranbolu inland and then the port of Sinop on the coast from the heirs of the Pervaneoğulları. Thereafter the beylik functioned in two complementary halves: Kastamonu as the dynastic capital and Sinop as its maritime window.

History & key rulers

Süleyman I acknowledged Ilkhanid suzerainty until the death of the last effective Ilkhan, Abu Sa'id, in 1335, after which he struck coins with the grandiose title "es-sultânü'l-a'zam" ("the most exalted sultan"). His son Ibrahim I ruled Sinop and gave the beylik a naval reputation: he captured about ten Genoese ships in Sinop's harbor and won a sea battle against a Venetian-Genoese fleet in 1341. Under Kötürüm Bayezid (1361–1383) the dynasty fought the rival Kadi Burhan al-Din of Sivas; in 1383 his son Süleyman II, backed by the Ottoman Murad I, seized Kastamonu and split the principality into Sinop and Kastamonu branches. Süleyman II was killed by Bayezid I in 1391/92, and the Ottoman sultan briefly absorbed the beylik. After Timur crushed Bayezid at Ankara in 1402, İsfendiyar Bey (1385–1440) was restored, holding Kastamonu, Kalecik, Tosya and Çankırı; pressured by Murad II, he withdrew to Sinop in 1423, and the line's last decades — Ibrahim II, Ismail, and the three-month reign of Kızıl Ahmed — were spent in the coastal remnant until Mehmed II took Sinop in 1461, extinguishing the longest-lived Anatolian beylik after the Karamanids.

Government, religion & culture

The Candar court was Sunni Muslim and cultivated a reputation for scholarship: the Moroccan traveler Ibn Battuta, visiting in 1331–32, described Süleyman Bey as a dignified ruler. Ismail Bey composed the Hulviyyât-ı Şâhî, a work of fiqh preserved in the Süleymaniye Library, and endowed a library of some 300 books. Surviving monuments include the Kötürüm Bayezid Mosque in Sinop and the Ibn Neccâr Mosque in Kastamonu.

Peak & territory

At its height the beylik controlled the Paphlagonian coast from around Sinop east and west along the Black Sea, plus the inland valleys of Kastamonu, Safranbolu, Çankırı and Tosya — a compact but wealthy state whose map footprint (1305–1332) reflects the coastal Sinop half at roughly 14,000 km².

Decline & legacy

The Ottoman-Timurid whipsaw of 1391–1402 permanently halved the dynasty, and Mehmed II's 1461 campaign erased it. Its legacy endures in Sinop's medieval walls, dockyards and mosques, and in the dynasty's reputation as a patron of learning among the beyliks.
