Hor Awibre's reign length is partially lost to a lacuna of the Turin canon and is consequently unknown.

[1][2] In any case, Hor most likely reigned only for a short time, in particular not long enough to prepare a pyramid, which was still the common burial place for kings of the early 13th dynasty.

(speculation) Hor remained unattested until the discovery in 1894 of his nearly intact tomb in Dashur by Jacques de Morgan, see below.

[1] At Tanis (Nile Delta region), in a secondary context, a granite architrave with the cartouches of Hor and Sekhemre Khutawy Khabaw was found.

[1] Based on this evidence, the egyptologist Kim Ryholt proposed that Sekhemrekhutawy Khabaw was a son and coregent of Hor Awibre.

[11] The tomb was originally made for a member of Amenemhat's court and was later enlarged for Hor, with the addition of a stone burial chamber and antechamber.

[19] Although the tomb had been pillaged in antiquity, it still contained a naos with a rare life-size wooden statue of the Ka of the king.

[23][24][25][26] No evidence has been found that relate Hor to his predecessor on the throne, Renseneb, which led Ryholt and Baker to propose that he was an usurper.
