Hamza Zenebishi or Amos Sarbissa (1456 - 60), was an Ottoman official of Albanian origin who served as the Sanjakbey of the Sanjak of Mezistre (named after its capital, Mystras).
He was born to the Zenebishi, a Christian Albanian noble family from the Zagori region, in modern southern Albania.[1] He was sent as a hostage to the Ottoman court after his family submitted to the Sultan and converted to Islam.
In 1459, Hamza defeated the forces of the Despots of the Morea besieging Patras.[2] In 1460, following the Ottoman conquest of the Morea, Hamza became the Sanjak-Bey of the Sanjak of Mezistre.[3]
