Kaznac (Serbian Cyrillic: казнац) was a court title of the state employee in medieval Bosnia and Serbia who was in charge for the treasury in the territory under his jurisdiction — kaznačina (казначина).
[1][2][better source needed] The name of the title is derived from Serbo-Croatian word kazna (English: penalty).
[3] The kaznac was a financial-taxation service, translated into Latin camerarius (itself rendered "chamberlain").
[4] In the Dečani chrysobulls, King Stefan Dečanski (r. 1321–1331) mentioned that the court dignitaries present at the Dečani assembly were the kaznac, tepčija, vojvoda, sluga and stavilac.
[5] The title of veliki kaznac (велики казнац, "grand kaznac") was later transformed into protovestijar.
