Gevherhan Hatun

Gevherhan Hatun () was an Ottoman princess, the daughter of Mehmed the Conqueror (reign 1444–46 and 1451–81) and Gülbahar Hatun. She was the sister of Sultan Bayezid II (reign 1481–1512).
Early life.
Gevherhan Hatun was the daughter of Sultan Mehmed II known as "The Conqueror", and his wife Gülbahar Hatun. She was the younger full sister of Sultan Bayezid II.
Marriage.
In 1474, Gevherhan married Ughurlu Muhammad, a son of Aq Qoyunlu ruler, Uzun Hassan. Ughurlu Muhammad had rebelled against his father and sought refuge by the Ottomans. Her father welcomed him and got him married to Gevherhan. 
Gevherhan's marriage to Ughurlu Muhammad was the only exception, which actually proved the rule. Ughurlu Muhammad being an exile from his own land and refugee at the Ottoman court, the Aq Qoyunlu prince might be considered a kind of adjunct member of the Ottoman royal household. 
Mehmed installed his new son-in-law in the frontier province of Sivas and promised to supply him with arms and men, with which he would assert his claim to his patrimony at the proper moment. Ughurlu Muhammad was killed in the rebellion he attempted against his father in 1477.
Of this marriage, Göde Ahmed was born. Because of his father's death, Mehmed had his grandson brought to Istanbul. Ahmed married his uncle Sultan Bayezid II's daughter Aynışah Hatun in 1489.
Death.
When she died, she was buried beside her mother in her mausoleum located in Fatih Mosque, Istanbul.

In the 2013 Turkish series "Fatih", Gevherhan Hatun is played by Turkish actress Hande Soral.
