Tomnatic (German: Triebswetter; Hungarian: Nagyősz) is a commune in Timiș County, Romania.

[4] Near Tomnatic took place the last battle between Ahtum, the leader of Romanians, Pechenegs and Bulgars in the rough territory of today's Banat, and the Hungarian invaders led by Chanadinus, a rebellious general of Ahtum, in 1003 or 1030 (the date of the battle is disputed).

[6] By 1451, it is mentioned under the name of Naghiuz ("Uzul Mare"), probably with reference to the Cuman population (Udi), who remained for a long time on the territory of the historical Banat.

[7] 200 houses were originally built, according to the plans of engineer Antonius von Triebswetter.

[8] Subsequently, 1,002 people from Tomnatic (almost a quarter of the population) were deported to the Bărăgan steppe, irrespective of ethnicity.

Most inhabitants are Romanians (78.44%), larger minorities being represented by Roma (6.77%), Hungarians (3.98%), Germans (3.88%) and Ukrainians (1.43%).

[11] The local economy is based on agriculture, the inhabitants being specialized in growing vegetables.
