The name Stephen (Serbo-Croatian: Stefan / Стефан, Stjepan / Стјепан, Stipan / Стипан, and others), long popular among South Slavic monarchs, was used as an honorific or as a royal title by various rulers of Serbia and claimants to the Serbian throne, most notably[1] the Nemanjić kings of Serbia and the Kotromanić kings of Bosnia.
