İbrahim II of Karaman

Ibrahim II (died 1464) was a bey of Karaman.

During the post-Seljuk era in the second half of the middle ages, numerous Turkmen principalities, which are collectively known as the Anatolian beyliks, emerged in Anatolia. Initially the Karamanids, centered on the modern provinces of Karaman and Konya, were the most important power in Anatolia. But towards the end of the 14th century the Ottomans began to dominate most of Anatolia, reducing Karamanid influence and prestige. Thus the campaign of Timur to Anatolia and the ensuing Ottoman Interregnum gave the Karamanids a chance for revival. However the Karamanids also experienced a period of interregnum during Ottoman interregnum, so they were unable to end Ottoman domination in Anatolia.

Ibrahim Bey was Mehmet Bey's son. He fought against his uncle Ali Bey, and with Ottoman support he ascended to throne in 1424. Nevertheless, their help did not ensure his fidelity to the Ottomans. He secretly allied himself with Kingdom of Hungary against them. During the Ottoman wars in Europe, he was able to capture the city of Beyşehir from the Ottomans. However, in 1433, Ottoman Sultan Murat II returned to Anatolia and Ibrahim sued for peace in 1435. Nevertheless, shortly after the peace, Ibrahim laid a siege on Amasya an important Ottoman city to which Murat reacted by supporting the Dulkadirids to capture the city of Kayseri and İsa, Ibrahim's brother, to capture Akşehir from Karamanids. Ibrahim was forced to lift the siege in 1437. During the following seven years peace prevailed in Anatolia. But in 1444 when a great crusader army began marching on the Ottoman capital, Ibrahim saw his chance and plundered Ottoman cities in Anatolia including Ankara and Kütahya. Murat, caught between two fires, had to sign the Treaty of Szeged with the crusaders and then returned to Anatolia and retaliated. Ibrahim was forced to sign a treaty with unfavarable terms (called sevgendname). Although after Murat's death Ibrahim allied himself with Venice, he didn't fight against the Ottomans.
