In 1779, Beșenova Veche was included in Torontál County and was governed by the laws of the Austrian state, in a permissive, democratic style, using the Bulgarian language in relations with its countrymen.

In 1787, when Gjura Lebanovici was mayor of Beșenova, the village was raised by Joseph II to the rank of town and was given the right to hold a weekly market every Thursday and, twice a year, on 15 May and 15 November, a fair.
