Strojimir of Serbia

Strojimir (; ) was the co-ruler of the Serbian Principality alongside his two brothers Mutimir and Gojnik, from ca 851 to his and Gojnik's deposition in the 880s after an unsuccessful coup against the eldest Prince Mutimir (r. 851–891).

He was a younger son of Vlastimir, who ruled in 836–851. Strojimir, together with his brothers Gojnik and Mutimir, defeated the Bulgarian Army sent by Boris I, led by his son Vladimir, who, together with 12 boyars was captured by the Serb Army. Peace was subsequently agreed and the two sons of Mutimir; Pribislav and Stefan Mutimirović escorted prisoners towards the border at Rasa. There Boris gave them rich gifts and was given 2 slaves, 2 falcons, two dogs, and 80 furs by Mutimir.
