Alaattin Ali of Karaman

Alaattin Ali of Karaman (aka Damat Ali Bey) was a bey of Karaman Beylik, a Turkish principality in Anatolia in the 14th century. Like most other Karaman beys, Ali Bey was a rival of the rising Ottoman Empire, and the two principalities engaged in chronic wars against one another.

His father was Halil Bey. After his brother Süleyman ascended to throne he was appointed as the governor of Ermenek. However, after his brother was assassinated in Karaman, he succeeded his brother in 1361. He had family ties to the Ottoman dynasty, for he married Nefise Hatun, Murat I's daughter.

In the 14th century Anatolia was in turmoil. In addition to Karaman beylik there were many other Anatolian beyliks. Ali invaded the territories of neighbouring beyliks; Hamidoğlu, Eretna and Germiyan. He even tried to raid Kadi Burhanettin's dominions, but without success.

Ottoman Sultan Murat was engaged in Rumeli (European section of the empire) and Ali saw his chance to capture Beysehir, an Ottoman fort in 1386. Murat returned to Anatolia and defeated Ali's forces in a location named Frenkyazısı, near Konya, the capital. According to Prefessor Halil İnalcık, the importance of this battle was that it showed the superiority of regular army over tribal forces. After Nefise's mediation however, Murat agreed to withdraw on the condition that Beyşehir be handed to Ottomans.
