Veliki vojvoda  Veliki vojvoda (; from "veliki" = great and "vojvoda" = duke) was a military and noble title in use during the Middle Ages and the Modern period in the Western Balkans. It is often translated into "grand duke". "Veliki vojvoda" was a title used in Serbia in the Middle Ages and the Kingdom of Bosnia (1380–1448). It signified superiority over the other "vojvodas". The title-holder commanded the army on occasions when the monarch did not attend in military campaigns, usually with lesser important military operations inside the country, or when a detachment was sent to aid allies. Another term used for the title was "standard-bearer" ("stegonoša", ). There are also mentions of the title-holders in Serbian epic poetry regarding the Battle of Kosovo, such as Dimitrije. The title was adopted in the Prince-Bishopric of Montenegro. Mirko Petrović-Njegoš bore the title, as "Grand Duke of Grahovo".
