In the Middle Ages, the region came under the control of the Magyars who absorbed the Slavic and the remnant Avar population. There was archaeological evidence found in various small villages in the Middle Ages. The area was under the ownership of János Hunyadi in the 15th century. With the arrival of the Turks, the population disappeared and was at first replaced by Croats who came from Bosnia and the Croatian Littoral. The first mention the village comes from 1543 in the records of the Archbishopric of Kalocsa. In the 17th century, there was a steady influx of Croats under the leadership of the Franciscans from Bosnia. The last major group came under the leadership of captains Marković and Vidaković. With the Turkish defeat at the Battle of Zenta, Bácsalmás came under the control of the Habsburgs where it became a part of the Military Frontier. In 1772, the village received an Urbarium form in the Croatian language, which reflected the majority of the population. The Urbarium was for the landowners of the village consisting of 72 Bunjevci, 11 Hungarians, 3 Slovaks and 2 Romani. In the 1780s, 195 German families were settled by the Habsburgs in Bácsalmás who continued to be the overwhelming majority until 1945. Most of these settlers came from Swabia, Alsace and Mainz. In the following decade, land grants were given to newly ennobled men from the immediate region to the Hungarian family of Németszeghy, Koronay, and Croat families of Antunović, Rudić, Kovačić, and Šišković. In the 19th century the town became a centre for wine and grain production which was exported mainly to Austria and Bohemia. It also became an important railroad junction. In effect it became a prosperous community. However, it retained its rural character the whole time with a strong artisan class which served the surrounding region. In 1941, the town had a population of 13,000, two-thirds of whom were Germans. In 1945–46, the majority of Germans were expelled and Hungarians were brought from Slovakia to replace them. In 1986, Bácsalmás became a town with a population of over 8,000. With the closure of some industries and the reforms in agriculture, the town is losing its population. Bácsalmás is struggling to replace the declining agricultural sector, but alternatives are hard to find. The farming cooperative privatized in the early 1990s and the localstate farm accumulated large debts.
