Shakkanakku
Shakkanakku (Sumerian: 𒄊𒀴, GIR.NITA or šagina, Akkadian: 𒇽𒃻𒃶𒅘𒆪, Shakkanakku), was an Akkadian-language title designating a military governor. Mari was ruled by a dynasty of hereditary Shakkanakkus which was originally set by the Akkadian Empire and gained independence following Akkad's collapse. It is considered that the Shakkanakkus gained some form of independence and came to be considered as "Kings" from the time of Apil-Kin. A critical analysis of the Shakkanakku List of Mari has been published.
The title is also known around the same time in Elam, where several "Shakkanakku (Military Governor) of the country of Elam" with typically Akkadian names ruled for the Akkadian kings.
The title also existed in Qatna in the 14th century BC, and Dilmun under the Kassites.
