Ilidza is one of the longest continuously inhabited regions in Bosnia and Herzegovina. Since the 19th century, numerous archeological finds have been made in the Butmir neighborhood, dating from Neolithic times. The so called Butmir culture, is one of the best documented Neolithic cultures in Europe of the 26th and 25th centuries BC.
During Roman times, the Ilidža area was the location of the town Aquae Sulphurae. This was a Roman colony, and the main settlement in all of Bosnia and Herzegovina at the time. Today numerous traces of Roman civilization have been found, such as mosaics, ceramics, jewelry, coins, and even structural remains.
During medieval times, the Ilidža area was part of the Bosnian province of Vrhbosna. Katera, one of the two original Bosnian towns mentioned by Constantine Porphyrogenitus in De Administrando Imperio, was found on the ground of today's Ilidža municipality. The disciples of Saint Cyril and Saint Methodius considered the area important enough to stop by Vrelo Bosne and build a church in the area.
The modern town of Ilidža as we know was founded during the Ottoman rule of Bosnia. Its name derives from the Turkish word Ilıca, meaning "warm thermal springs". (Ilıca is also the name of a district of Erzurum, a southeast city of Turkey. There are also Ilıca named municipalities in the following provinces of Turkey: Samsun, Kahramanmaraş, Antalya, Malatya, Ordu.) Numerous elements of Turkish culture found their way into Ilidža, such as a number of oriental homes from the 15th and 16th centuries that have survived to this day. Numerous mosques and bridges were also built at this time.
Ilidza, like the rest of Bosnia, experienced industrialization and westernization with the coming of Austria-Hungary. A railroad station and tracks, hotels, and various other structures made Ilidza the most important town after Sarajevo in the region. This continued into the 1900s as Ilidza continued to grow and develop
