Gülçiçek Hatun

Gülçiçek Hatun (; - ), was a Greek woman from Bithynia who became a concubine of Ottoman Sultan Murad I and Valide Hatun to their son Bayezid I.

Biography According to a tradition, Gülçiçek was a concubine of Aclan Bey, one of the Karasid princes. She was captured when Orhan conquered the principality ( 1344) and placed in the Sultan's harem. However, modern historians do not accept this claim. It is believed that the wife of Aclan Bey and Murad’s concubine were two separate women. Around 1359, when Orhan's son Murad had reached adulthood, she became his concubine.

She bore Murad two sons, Bayezid I and Yahşi Bey. She appointed her son Yahşi as trustee for an endowment deed she made for a Dervish Monastery. In her lifetime she established a religious and charitable foundation which demonstrated her Muslim piety publicly. With its revenues she built a mosque, the first Ottoman concubine to build one, and a tomb in Bursa where she was buried when she died, around 1400.
