When Sultan Alaeddin Keykubad I conquered Alanya in 1221, he didn't just win a fortress - he won a bride. As part of the surrender agreement, the Byzantine commander Kyr Vart offered his daughter, Princess Destina, in marriage to the Sultan.
Destina was renamed "Mahperi" (Moon-Like Lady) and given the title "Hunat Hatun" (Great Lady). Against all expectations, the captive princess didn't merely survive - she thrived. She converted to Islam, learned Turkish, and became the Sultan's most trusted advisor.
When Sultan Alaeddin was poisoned by rivals, Mahperi faced the greatest challenge of her life. Another wife, Melike Adil, wanted her own son on the throne. What followed was a brutal succession war fought in shadows - with assassinations, bribes, and political maneuvering.
Mahperi won. Her son, II. Gıyaseddin Keyhüsrev, became Sultan, and she became regent - effectively ruling the Seljuk Empire. Her enemies met harsh fates: Melike Adil was imprisoned in Ankara Castle, her sons murdered in Borgulu Castle, her daughters exiled.
A Sufi legend claims Sheikh Turasan Veli converted Mahperi to Islam through a mystical vision. She became deeply religious, building mosques, caravanserais, and madrasas across Anatolia. The Mahperi Hatun Kervansarayı on the Silk Road still stands after 800 years.
Her tomb inscription reads: "Saffetü'd-dünya ve'd-Din" - The Purity of the World and Faith. A title usually reserved for male rulers.
