What is "dobravac"

Dobravac (; 1280) or Dobravec was a Serbian nobleman serving in the crown land of Hum, with the title of tepčija. He is mentioned in a document dated 1280 as serving the countess of Hum . He had a clerk or assistant, Mojše, who sold two of his bondmaids in Ragusa (Dubrovnik) that year. Although Dobravac's jurisdiction is unknown from the quotation, he was not a veliki tepčija (serving the king directly); his office was limited to the Hum land, but his type of work was the same as that of the veliki tepčija. The tepčija had executive authorities; his otroci ( otrok), were servants, lesser in rank but not slaves.
