In short: Nestled in the valley of the Trebišnjica river, Trebinje has served as a pivotal military and economic hub for centuries. From its origins as a medieval stronghold to its role as a contested borderland during the Ottoman and Austro-Hungarian eras, the city remains a testament to shifting imperial power.

The history of Trebinje is defined by its position on the vital communication route between Ragusa and Constantinople. Known originally as Tribulium, the settlement was mentioned as Travunija in the 10th-century work De Administrando Imperio. By the late 12th century, it was incorporated into the Serbian Kingdom and later the medieval Bosnian state. Its strategic importance grew significantly after it was captured by the Ottoman Empire in 1478. The Ottomans reshaped the town into an Oriental-Mediterranean center, constructing the walled Old Town, or Kastel, during the 17th century, and adding mosques and stone bridges, most notably the 16th-century Arslanagić Bridge.

Throughout the centuries, the region was a frequent theater of conflict. In March 1655, hajduk bands carried out a major raid on the town, while in 1716, a combined Austro-Venetian-Hajduk force of 7,000 soldiers besieged the city's walls, which were defended by 1,000 Ottoman troops. The 19th century brought further upheaval, including anti-Ottoman uprisings and conflicts against Napoleonic forces. Following the Austro-Hungarian occupation in 1878, the city was modernized with new infrastructure, schools, and tobacco plantations, though it also became a site of significant repression during the First World War, when volunteer corps terrorized the local population.

In the 20th century, Trebinje experienced rapid industrial growth under the Socialist Federal Republic of Yugoslavia, particularly through the exploitation of the Trebišnjica river for hydroelectric energy. During the Bosnian War in the 1990s, the city served as a major command and artillery base for the Yugoslav People's Army. Today, Trebinje is the economic center of East Herzegovina, hosting the headquarters of Elektroprivreda Republike Srpske. While its history is marked by the destruction of its religious heritage during the 1990s, the city has since seen significant urban development, including a new hospital opened in 2026 and a boom in modern residential construction.
