Olovo () is a town and municipality located in the Zenica-Doboj Canton of the Federation of Bosnia and Herzegovina, an entity of Bosnia and Herzegovina. It is situated about 50 kilometers northeast of the capital city of Sarajevo. History The town Olovo was first mentioned in the year 1382 under the name "Plumbum" (Latin for lead). The word olovo in Bosnian means lead, and the name was given to the town for its well-known lead ore deposits. Olovo stands on the Sarajevo–Tuzla highway M18, and is located 50 km northeast of Bosnia and Herzegovina's capital city of Sarajevo. Olovo is located in the Zenica-Doboj Canton. Recently, there have been attempts to make Olovo part of the Sarajevo Canton; however, the town remains within the Zenica-Doboj Canton . Since the Middle Ages, the town has been well known for its lead ore deposits, and Olovo was a mining town during medieval Bosnian state period, when the town and the region were part of the Pavlović's Land (). During WW2, Olovo came under the occupation of the Independent State of Croatia in 1941. On 1 November 1941, four Chetnik companies with 400 Chetniks and parts of Partisan Romanija Detachment (Knežina, Bjelogoračka and Crepoljska companies) and Zvijezda Detachment (Nišić battalion and Crnovrška and Vlahinjska company) with total of 800 Partisans organized an unsuccessful attack on Olovo. The insurgents then stopped their artillery fire and replaced it with barrages of rifle fire of the infantry insurgent units. The commander of the 4th company of Sarajevo Reserve Battalion, Ante Marinković was wounded during this attack and his company had to retreat from "Stijena". After being inforced by one reserve platoon this company managed to recapture "Stijena" for short time only to retreat after being attacked by more numerous Chetnik forces. When Chetniks permanently captured "Stijena" they burned straws as signal to other insurgents about their success. This boosted morale of the insurgents to attack more fiercely the positions of Olovo garrison that began retreating from their positions. To avoid capture of his forces, garrison commander Streharski retreat to the positions west of the village Solun. On 17 December 1941 Olovo was recaptured by Chetnik and Partisan rebel units. On 18 December Streharski continued his retreat under fire until his forces reached Careva Ćuprija.
