Zacharias III of Makuria

Zacharias III (Arabic: Zakarya ibn-Bahnas‎‎) (c. 822 – c. 854) was ruler of the Nubian kingdom of Makuria. In 833 he ceased paying the Baqt to the rulers of Egypt, and prepared to fight the Abbasid Caliph al-Mu'tasim (833-842) over the tribute. He sent his son Georgios (Arabic: Firaki) to renegotiate the terms, and al-Mu'tasim reduced the payment to once every third year.

When the Beja refused to pay their tribute to the Abbasids in 854, the forces of Makuria joined with them in attacking Egypt. They slew the Egyptian working the emerald mines in the Eastern Desert, invaded Upper Egypt and pillaged Edfu, Asna and many other villages.¹
