# Banja Luka

Banja Luka (Serbian Cyrillic: Бања Лука, pronounced ) or Banjaluka (Serbian Cyrillic: Бањалука, pronounced) is the second largest city in Bosnia and Herzegovina and the largest city of Republika Srpska. Banja Luka is the traditional centre of the densely-forested Bosanska Krajina region of northwestern Bosnia. According to the 2013 census, the city proper has a population of 138,963, while its administrative area comprises a total of 185,042 inhabitants.
The city is home to the University of Banja Luka and University Clinical Center of the Republika Srpska, as well as numerous entity and state institutions for Republika Srpska and Bosnia and Herzegovina, respectively. The city lies on the Vrbas river and is well known in the countries of the former Yugoslavia for being full of tree-lined avenues, boulevards, gardens, and parks. Banja Luka was designated European city of sport in 2018.

## Name

The name Banja Luka was first mentioned in a document dated to 6 February 1494 by Ladislaus II of Hungary. The name is interpreted as the 'Ban's meadow', from the words ban (a medieval noble title), and luka ('valley' or 'meadow'). The identity of the ban and the meadow in question remains uncertain, and popular etymology combines the modern words banja ('bath' or 'spa'), or bajna ('marvelous') and luka ('port'). A different interpretation is suggested by the Hungarian name Lukácsbánya, in English 'Luke's Mine'. In modern usage, the name is pronounced and occasionally written as one word (Banjaluka).

## Geography
### Overview

Banja Luka covers some 96.2 km$^2$ (37.1 sq mi) of land in Bosnia and Herzegovina and is situated on both banks of the Vrbas in the Banja Luka valley, which is characteristically flat within the otherwise hilly region. Banja Luka's centre lies 163 m (534.78 ft) above sea level.
The source of the Vrbas River is about 90 km (56 mi) to the south at the Vranica mountain. Its tributaries—the Suturlija, the Crkvena, and the Vrbanja—flow into the Vrbas at various points in the city. A number of springs can be found nearby.
The area around Banja Luka is mostly woodland and acre fields, although there are many mountains further from the city, especially south from the city. The most notable of these mountains are Ponir (743 m), Osmača (950 m), Manjača (1,214 m), Čemernica (1,338 m), and Tisovac (1,173 m). These are all part of the Dinaric Alps mountain range.

## History
### Roman times

The history of inhabitation of the area of Banja Luka dates back to ancient times. There is substantial evidence of Roman presence in the region during the first few centuries A.D., including the fort "Kastel" (Latin: Castra) in the centre of the city. The area comprising Banja Luka was entirely in the kingdom of Illyria and then a part of the Roman province of Illyricum, which split into provinces of Pannonia and Dalmatia of which Castra became a part. Ancient Illyrian maps call the settlement in Banja Luka's present day location as Ad Ladios, a settlement located on the river Vrbas.

### Middle Ages

Slavs settled in the Balkans in the 6th century. Mediaeval fortresses in the vicinity of Banja Luka include Vrbas (1224), Župa Zemljanik (1287), Kotor Varoš (1323), Zvečaj (1404), and Bočac (1446). In one document written by king Vladislav II on 6 February 1494 Juraj Mikulasić was mentioned as castellan of Banja Luka. Below the town was a smaller settlement with one Catholic monastery.

### Ottoman rule

Banja Luka fell to the Ottomans in 1527. It became the seat of the Sanjak of Bosnia some time prior to 1554, until 1580 when the Bosnia Eyalet was established. Bosnian beylerbeys were seated in Banja Luka until 1639. Ferhad Pasha Sokolović, a relative of Grand Vizier Mehmed-pasha Sokolović, had upon his return to Bosnia in 1574, begun the building of over 200 buildings ranging from artisan and sales shops to wheat warehouses, baths and mosques. Among more important commissions were the Ferhadija and Arnaudija mosques during whose construction plumbing infrastructure was laid out, that served surrounding residential areas. This stimulated the economic and urban development of Banja Luka, which soon became one of the leading commercial and political centres in Bosnia. It was also the central sanjak in the Bosnia Eyalet. In 1688, the city was burned down by the Austrian army, but it quickly recovered. Later periodic intrusions by the Austrian army stimulated military developments in Banja Luka, which made it into a strategic military centre. Orthodox churches and monasteries near Banja Luka were built in the 19th century.
In the 19th century, Sephardic Jews and Trappists migrated to the city and contributed to the early industrialization of the region by building mills, breweries, brick factories, textile factories, and other important structures. The Trappist monastery built in the 19th century lent its name to the neighbourhood of Trappisti and has left a large legacy in the area through its Trappist cheese and its beer production.
In 1835 and 1836, during Ottoman administration, numerous people from Banja Luka emigrated to Lešnica, Lipnica, and Loznica, the villages around Loznica, and to Šabac.

### Austro-Hungarian rule

Despite its leading position in the region, Banja Luka as a city was not modernised until Austro-Hungarian occupation in the late 19th century. Railroads, schools, factories, and infrastructure appeared, and were developed, which turned Banja Luka into a modern city.

### Yugoslavia

After World War I, the town became the capital of the Vrbas Banovina, a province of the Kingdom of Yugoslavia. The provincial capital owed its rapid progress to the first Ban Svetislav Milosavljević. During that time, the Banski dvor and its twin sister, the Administration building, the Serbian Orthodox Church of the Holy Trinity, a theatre and a museum were built, the Grammar School was renovated, the Teachers College enlarged, a city bridge was built and the park renovated. 125 elementary schools were functioning in Banja Luka in 1930. The revolutionary ideas of the time were incubated by the "Pelagić" association and the Students' Club. Banja Luka naturally became the organisational centre of anti-fascist work in the region.

#### World War II

During World War II, Banja Luka was occupied by Axis troops and was included into the Independent State of Croatia, a Nazi puppet-state led by Pavelić's Ustaše. Most of Banja Luka's Serbs and Jews were deported to concentration camps such as Jasenovac and Stara Gradiška. The Jasenovac camp was one of the largest extermination camps in Europe, which was notorious for its high mortality rate and the barbaric practices which occurred in it. On 7 February 1942, Ustaše paramilitaries, led by a Franciscan friar, Miroslav Filipović (aka Tomislav Filipović-Majstorović), killed more than 2,300 Serbs (among them 500 children) in Drakulić, Motike and Šargovac (a part of the Banja Luka municipality).
The city's Cathedral of Christ the Saviour and Orthodox church of the Holy Trinity were totally demolished by the Ustaše, as was the Church of St. George in Petrićevac. The Bishop of Banja Luka, Platon Jovanović, was arrested by the Ustaše on 5 May 1941, and was tortured and killed. His body was thrown into the Vrbanja river. The city was liberated by the Yugoslav Partisans on 22 April 1945.

#### 1969 earthquake

On 26 and 27 October 1969, two devastating earthquakes (6.0 and 6.4 on the Richter scale) damaged many buildings in Banja Luka. Around 20 to 23 people were killed, and over a thousand injured. A large building called Titanik in the centre of the town was razed to the ground, and the area was later turned into a central public square. With contributions from all over Yugoslavia, Banja Luka was repaired and rebuilt. During this period a large Serb population moved to the city from the surrounding villages, and from more distant areas in Herzegovina.

### 1992-1995 Bosnian War
#### 1994 Banja Luka incident

On 28 February 1994, an incident occurred in which four Republika Srpska Air Force aircraft, which had violated Bosnia's no-fly zone and bombed a factory, were shot down southwest of Banja Luka by planes from the United States Air Force on behalf of NATO, marking the first active combat action in the alliance's history.

## Government

Banja Luka plays an important role on different levels of Bosnia and Herzegovina's government structures. Banja Luka is the centre of the government for the Municipality of Banja Luka. A number of entity and state institutions are seated in the city. The Republika Srpska Government and the National Assembly are based in Banja Luka.
The Bosnia and Herzegovina State Agencies based in the city include the Indirect Taxation Authority, the Deposit Insurance Agency as well as a branch of the Central Bank of Bosnia and Herzegovina (formerly the National Bank of Republika Srpska). Austria, Croatia, France, Germany, Serbia, the United Kingdom and the United States maintain diplomatic representation through consulates-general in Banja Luka.
As of 2021, the mayor is Draško Stanivuković of the Party of Democratic Progress, elected in 2020.

## Economy

In 1981, Banja Luka's GDP per capita was 97% of the Yugoslav average.
Although the city itself was not directly affected by the Bosnian war in the early 1990s, its economy was. In this period Banja Luka fell behind the world in key areas such as technology, with socially owned technology firms such as SOUR Rudi Čajavec collapsing, resulting in a rather stagnant economy. However, in recent years, the financial services sector has gained in importance in the city. In 2002, the trading began on the newly established Banja Luka Stock Exchange. The number of companies listed, the trading volume and the number of investors have increased significantly. A number of big companies such as Telekom Srpske, Rafinerija ulja Modriča, Banjalučka Pivara and Vitaminka are all listed on the exchange and are traded regularly. Investors, apart from those from Slovenia, Croatia and Serbia, now include a number of investment funds from the EU, and from Norway, the United States, Japan and China.
A number of financial services regulators, such as the Republika Srpska Securities Commission and the RS Banking Agency are headquartered in Banja Luka. This, along with the fact that some of the major banks in Bosnia, the Deposit Insurance Agency and the value-added tax (VAT) authority are all based in the city, has helped Banja Luka establish itself as a major financial centre of the country.
