İsfendiyar Bey

Mubāriz al-Dīn Isfendiyār Bey (Old Anatolian Turkish: ; – 26 February 1440), was a member of the Candar dynasty that reigned as ''bey'' from 1385 until his death in 1440. Although the name of the dynasty is ''Candar'', following his reign, as a testament to its longevity certain historians of the Ottoman Empire also began to refer to the beylik by the name ''İsfendiyar.''

Early life

Isfendiyār was the son of Süleyman II of the princely Candar dynasty, while his mother was Sultan Hatun of the imperial Ottoman dynasty, daughter of Süleyman Pasha, son of the second Ottoman sultan Orhan.

Ascendance

Before his enthronement, the Beylik of Candar had been reduced to a small area around Sinop, a port on the Black Sea coast. In a bid to avoid the loss of his last dominion, as ''bey'' İsfendiyar adopted a policy of maintaining peace with his neighbors.

During the reign of the Ottoman Sultan Bayezid I (1389–1402), who had conquered most of the other beyliks of Anatolia, İsfendiyar was able to establish good relations with the other Oghuz Turkic clans. It is believed that the emergence of Kadı Burhaneddin's short lived but powerful Turkmen state in the Central Anatolia was one of the main factors for Ottoman- Candar cooperation.Research by Yaşar Yücel p.160
Nevertheless, several beys whose territory had been annexed by the Ottomans took refuge in İsfendiyar Bey's beylik.

Expansion

During Timur's campaign in Anatolia in 1402, he kept the territory of his beylik with Timur's approval. During the Ottoman Interregnum (1402–1413), he followed a balanced policy between the contestants. During the reign of Mehmed I of the Ottoman Empire (1413–1421), he was an ally of the Ottomans.Prof. Yaşar Yüce-Prof. Ali Sevim: ''Türkiye tarihi'' Cilt I, AKDTYKTTK Yayınları, İstanbul, 1991 pp. 202-293

Kazım’s revolt and final years

In 1416, his son Kazım, with Ottoman support, revolted which forced İsfendiyar Bey to abandon all territory south of the Ilgaz Mountains (i.e. Çankırı). In 1419, the Ottomans annexed the eastern part of the beylik (i.e. Samsun). The death of Mehmed I and the two revolts during the early years of the new sultan Murad II gave İsfendiyar a chance to regain his losses. However, after Murad II stabilized his domestic situation, İsfendiyar was quickly defeated.

According to the terms of the treaty signed circa 1423, İsfendiyar Bey was to abandon his gains but was permitted to keep the territories of Kastamonu and Sinop.

In latter years, İsfendiyar established close familial ties with the Ottomans, firstly with the marriage of his eldest daughter Tacünnisa Hatice Halime Hatun to Murad II, followed by the marriage of his eldest son and heir Tâceddin Ibrâhim II Bey to Selçuk Hatun, daughter of Mehmed I and half-sister of Murad II.
