Rabia Bala Hatun

Rabia Bala Hatun (died 1324) was the second wife of Osman I, founder of the Ottoman dynasty, and the daughter of Sheikh Edebali, the influential Sufi sheikh who was Osman's mentor and girded him with the sword of a gazi. Her marriage to Osman bound the brotherhood of the Akhıs to his rising beylik.

She was the mother of Alaeddin Ali Pasha, an adviser to Orhan. She died at Bilecik in January 1324 and was buried beside her father in the tomb complex built there by Orhan.
