Tuzla (Тузла, tûzla) is the third-largest city of Bosnia and Herzegovina and the administrative center of Tuzla Canton of the Federation of Bosnia and Herzegovina. As of 2013, it has a population of 110,979 inhabitants.
Tuzla is the economic, cultural, educational, health and tourist centre of northeast Bosnia. It is an educational center and is home to two universities. It is also the main industrial machine and one of the leading economic strongholds of the country with a wide and varied industrial sector including an expanding service sector thanks to its salt lake tourism.
The city of Tuzla is home to Europe's only salt lake as part of its central park and has more than 350,000 people visiting its shores every year. The history of the city goes back to the 9th century; modern Tuzla dates back to 1510 when it became an important garrison town in the Ottoman Empire.
In Bosnia and Herzegovina, Tuzla is also regarded as one of the most multicultural cities in the country and has managed to keep the pluralist character of the city throughout the Bosnian War and after, with Bosniaks, Serbs, Croats and a small minority of Bosnian Jews residing in Tuzla.
The name Tuzla is the Ottoman Turkish word for salt mine, tuzla, and refers to the extensive salt deposits found underneath the city. Leveraging on their shared name, the city is twinned with Tuzla, a suburb of Istanbul, Turkey.
Archaeological evidence suggests that Tuzla was a rich Neolithic settlement. Being inhabited continuously for more than 6,000 years, Tuzla is one of the oldest European sustained settlements. During the period of the Roman Republic (before the area was conquered by Rome), Tuzla (or Salines as it was called at the time) was ruled by the Illyrian tribe Breuci.
The city was first mentioned in 950 by Constantine Porphyrogenitus in his De Administrando Imperio as a fort named Salines (Σαλήνες). The name Soli was used in the Middle Ages. It means "salts" in Bosnian and the city's present name means "place of salt" in Ottoman Turkish.
