Bosna (river) in the context of "Battle of the Bosnian Highlands"

The Butmir culture was a major Neolithic culture in central Bosnia, developed along the shores of the river Bosna, spanning from Sarajevo to Zavidovići. It was discovered in 1893, at the site located in Butmir, in the vicinity of Ilidža, which gave its name to an entire cultural group of the Late Neolithic in central Bosnia, the Butmir culture. It is characterized by its unique elaborately decorated pottery and anthropomorphic Figurines, and is one of the best researched European cultures from 5100 to 4500 BC. It was part of the larger Danube civilization. The largest Butmir site is in Visoko basin, in Okolište.

The Sava is a river in Central and Southeast Europe, a right-bank and the longest tributary of the Danube. From its source in Slovenia it flows through Croatia and along its border with Bosnia and Herzegovina, and finally reaches Serbia, feeding into the Danube in its capital, Belgrade.

The Sava is 990 kilometres (615 miles) long, including the 45-kilometre (28 mi) Sava Dolinka headwater rising in Zelenci, Slovenia. It is the largest tributary of the Danube by volume of water, and the second-largest after the Tisza in terms of catchment area (97713km²) and length. It drains a significant portion of the Dinaric Alps region, through the major tributaries of Drina, Bosna, Kupa, Una, Vrbas, Lonja, Kolubara, Bosut and Krka. The Sava is one of the longest rivers in Europe and among the longest tributaries of another river.

It is situated in central Bosnia and Herzegovina, located between Doboj and Zenica on the confluence of rivers Bosna, Krivaja and Gostović.

Visoko (Serbian Cyrillic: Високо, pronounced [ʋǐsɔkɔː]) is a city located in the Zenica-Doboj Canton of the Federation of Bosnia and Herzegovina, an entity of Bosnia and Herzegovina. As of 2013, the municipality had a population of 39,938 inhabitants with 11,205 living in Visoko town. Located between Zenica and Sarajevo, Visoko lies where the river Fojnica joins the Bosna.

The Visoko region has evidence of long continuous occupation, with the first traces of life dating back to the 5th millennium BC. Archaeological excavations of Okolište have found one of the biggest Neolithic settlements of the Butmir culture in southeastern Europe.

Zenica (/ˈzɛnɪtsə/ ZEN-it-sə; Bosnian pronunciation: [zěnitsa] ) is a city in Bosnia and Herzegovina and an administrative and economic center of the Federation of Bosnia and Herzegovina's Zenica-Doboj Canton. It is located in the Bosna river valley, about 70 km (43 mi) north of Sarajevo. The city is known for its Ironworks Zenica factory but also as a significant university center. According to the 2013 census, the settlement of Zenica itself counts 70,553 citizens and the administrative area 110,663, making it the nation's fourth-largest city.

The urban part of today's city was formed in several phases, including Neolithic, Illyrian, the Roman Municipium of Bistua Nuova (2nd–4th century; old name of the city), with an early Christian dual basilica. Traces of an ancient settlement have been found here as well; villa rustica, thermae, a temple, and other buildings were also present. Earliest findings in the place date from the period 3000–2000 BC; they were found in the localities of Drivuša and Gradišće. Zenica's current name was first mentioned in 1415. A medieval church has been unearthed in Zenica, as well as the Franciscan Monastery of St. Mary. The independence of Medieval Bosnia is directly connected to Zenica (Gradješa's plate and abjuration act; Kulin ban's time; Vranduk, a castle of the Bosnian kings; Janjići and 'hižas' [homes] of Bosnian Church members; stećci, stone tombstone monuments, etc.) During Ottoman rule (1463–1878), Zenica became a Muslim town; at the end of the 17th century, Zenica had 2,000 citizens, mostly Muslims; Orthodox and Catholic Christians are mentioned again from the end of the 18th century, and Jews in the 19th century. Modern Zenica was mostly built in the Austro-Hungarian and Yugoslavian periods. The population rose rapidly during the 20th century, and from the Bosnian War until 2013, the city lost a quarter of its population. The municipality of Zenica became the City of Zenica in 2014.

Bosnia (Greek: Βοσωνα, romanized: Bosona, Serbo-Croatian: Босна, Bosna) in the Early Middle Ages to early High Middle Ages was a territorially and politically defined South Slavic entity. It was situated, broadly, around the upper and middle course of the Bosna river, between the valleys of the Drina river on the east and the Vrbas river on the west, which comprise a wider area of central and eastern modern-day Bosnia and Herzegovina.
