Hapach

Not much is known about Hapach's life or much of his reign, only that he, with his army of horsemen and allied principalities, attacked Sarkel, a city of the Khazars, in the 900s. The Khazar army was defeated and the Sarkel prince and his surviving army were imprisoned.^[1][2]

The exact borders of the kingdom during his reign is also unknown. In historical sources, the area first appears in the 6th century, when the Byzantine historian Procopius of Caesarea^[3] records that the people of the Zechoi used to have a king appointed by the Roman Emperor, but that they had since become independent.^[4] The Notitiae Episcopatuum of the Patriarchate of Constantinople mention an autocephalous archbishopric of Zichia from the 7th century on, associated with Tamatarcha or the Cimmerian Bosporus.^[4]
