Şehzade Abdullah
Şehzade Abdullah was an Ottoman prince, son of Ottoman Sultan Suleiman the Magnificent and his favorite Hurrem Sultan. He was born around 1525 in Eski Saray, the Ottoman Empire and died due to a disease, possibly smallpox, in Constantinople, around 1528. He was buried in the Yavuz Selim Mosque
Although sometimes popularly considered, current historians believe he was not Mihrimah Sultan's twin as it is likely their births happened years apart.
