1718 the Banat region was put under Austrian rule by the peace-treaty of Passarowitz after 164 years of Turkish (Ottoman) occupation. After that German-speaking, catholic settler from the Holy Roman Empire (Of German Nation) were settled during three periods, the so-called „Schwabenzuege“.
Carlottenburg was founded in 1771 in the course of the second setteling period (1763-1772).
It was a new foundation. In the Josephinian Land Survey from 1770 it has not appeared yet. In the same year the other villages in the Bergsau (Beregsau) vally were also founded: Altringen, Neuhof (Bogda), Buchberg (Sintar) and Lichtenwald (Comeat). The construction works went on under the management of the impopulation director Carl Samuel Neumann Edler of Bucholt.
30 [Petri] or 32 [Griselini] families were settled there. 67 of the colonists came from the region east of Trient, 12 from Lorraine, 10 from Baden-Württemberg, 8 from Hungary, 7 from Rhineland and Rhineland-Palatinate, 6 from Austria, 3 from Bavaria and individuals from other regions.
The colonists were handed over 412 cadastral acre (1 cadastral acre = 0,5755 ha).
The etymology of the village name is not known [Fortiu]. For sure it was not named after the wife of the President of Banat administration Karl Ignaz Earl of Clary and Aldringen [Petri]. The name Barita [Toroc] first appears on a map in 1864.
During the handover of the Banat region to Hungary in 1778 the area was mapped in detail for the first time. Three maps regarding Charlottenburg can be admired in the Urbarium.
