Hacı Emir İbrahim Beg

Hacı Emir İbrahim Beg was the son of Bayram and ruler of the Black Sea beylik later named Hacıemiroğulları after him. By 1357 he was raiding Trebizond's lands around Maçka, and in 1358 sealed peace by marrying Theodora, daughter of Emperor Basil.

A Giresun campaign failed in 1361, but backed by his ally Kadı Burhaneddin he took Cotyora (Ordu) in 1380 and moved his capital to nearby Eskipazar.
