Hacı Sufi Burhanettin Musa, was a bey of Karaman Beylik, a Turkish principality in Anatolia in the 14th century.
[1] Although he appointed his brother Yahşi as the governor of Konya, the Seljuk capital, Emir Coban, the Mongol commander, captured the city and Musa had to be contended with the former possessions of his beylik.
However, he even lost Karaman, his capital city (ancient Larende) to his rebelling brother İbrahim, who was backed by the Mamluk Sultanate of Egypt.
But in 1352, after a chaos period in the beylik, he was invited to Karaman, where he ruled till 1356.
In his last days, he went to battle with the Armenian Kingdom of Cilicia and took many of their territories.
