Jamal al-Din Ushshaqi was born in Edirne and became known as the pir of the Cemaliyye branch of the Ushshaqiyye line of the Halveti order. He came to Istanbul in 1155/1742 and began his guidance activity, soon gathering a wide following. He served as sheikh at the Cemalizade (Savaklar) Lodge near Eğrikapı. He died in 1164/1751 and was buried in his tomb in the cemetery of that lodge. The site of the lodge lies on the Eğrikapı line at the boundary between Eyüp and Fatih (outside/inside the land walls); while sources support Eyüp, in modern administrative classification it may be attached to Fatih.
