The Smolyani (; in Byzantine sources Smolenoi or Smoleanoi) were a medieval Slavic tribe that settled in the Rhodope Mountains, the valley of the Mesta River and the region around Blagoevgrad Province, possibly in the 7th–8th century. The tribe revolted against the Byzantine authorities of Constantinople in 837 and were supported by Bulgarian ruler Presian, who, together with his deputy Kavhan Isbul, crossed the lands of the Smolyani and conquered the territory as far south as Philippi, including most of Macedonia. Their name etymologically derives from the Proto-Slavic word *smola ('resin'),

The Ichirgu-boila or Chargobilya (; Old Bulgarian: , ) was a high-ranking official in the First Bulgarian Empire. The holder of the post was the commander of the garrison of the capital and was the third most important person in the state after the ruler and the Kavkhan. In peace-time the ichirgu-boila had diplomatic functions. According to some data the ichirgu-boila personally commanded a squad of 400 heavy cavalrymen.
