Before the World War II, the village was called Buljkes, and was inhabited chiefly by ethnic Germans, settled here around 1786, mostly from Baden-Württemberg. In 1944, many of the residents fled ahead of the advancing Russian and Partisan troops. Under the newly enacted AVNOJ laws, in December 1944 the remaining residents were forced to relocate to the newly established concentration camp at Bački Jarak and the village was abandoned.
In May 1945, 4,650 Greek refugees, mostly male members of ELAS, settled in the village with the help of Yugoslav government. From 1945 to 1948, it was a sui generis case of Greek extraterritorial jurisdiction. The Yugoslav conflict with the Informbiro saw the Greek community divided between loyalty to Yugoslavia and to the Comintern, and those who supported the latter left the country. The remaining also emigrated to Greek Macedonia eventually, with only a few remaining.
The final settlement of the village started in late 1949, and ended around 1953. Settlers, chiefly Serbs, came in several waves, from all over the Yugoslavia. The village took the current name in 1949, after the Maglić mountain in eastern Herzegovina. The name partly evocates the sentiment of some settlers from that area, and partly subsumes the multi-original nature of the villagers, as it lies on junction of Bosnia, Herzegovina and Montenegro.
