[1] In German the original term used for these subdivisions was Districte[1] (modern spelling Distrikte).

In Bach's reforms from 1853[4] (formally applied to the crown land in 1854[2]) the Districte became Kreise, a form of administrative division already in use across much of the non-Hungarian part of the Empire since the 18th century.

The change of name was not superficial – different political, administrative and judicial structures were used in each subdivision type.

The Lugos District comprised the easternmost parts of Banat (the Military Frontier notwithstanding).

It shared borders with the Temesvár District to the west, the Banat Military Frontier in the south and east, the Grand Principality of Transylvania (initially the Karlsburger Kreis, Kreis Broos from 1854) in the north-east, and the Hungarian Arad County in the north (all parts of the Austrian Empire).
