The Sanigs (Greek: Σάνιγκι) were a tribe inhabiting historical Heniochia, northwest shore of Kingdom of Colchis(modern day northwestern Georgia).
[1] They are first attested in the works of Pliny, Arrian[2] and Memnon of Heraclea.
Historical territories of Heniokhet-Sanikheti(Sanigia) was divided into three parts: Sanigs inhabited the Inner Heniochia[3] Georgian scholars consider them to be Zans (ancestors of Mingrelian and Laz peoples), while others maintain that they were proto-Svans.
[4][5] According to Arrian, they inhabited the area around Sebastopolis (modern Sukhumi).
In favour of the Sanigs' Kartvelian (either Zan or Svan) origin, it is important to mention some modern Georgian surnames such as: Sanikidze, Sanikiani, Sanigiani, Sanaia[6] Some Abkhazians consider the Sanigs to be the ancestors of the Sadz and Zhaney, as evidenced by the territorial settlement of these peoples.
