The area of the municipality iscoextensive with the formerKolonjë District, one of the 36districts of Albania, which were dissolved in July 2000 and replaced by 12counties.
Kolonjë is located in south-east Albania and its capital isErsekë. Other towns in this district includeLeskovik to the south. It is bounded byKorçë to the north andGreece to the east, including the regional units ofKastoria andIoannina. The town of Ersekë is located at the foot of mountGramos, Albania's fourth-highest mountain with a peak at 2,525 m above sea level.
During the Middle Ages a region under the name Koloneia (Greek: Κολωνεία) is located in the mountain region south ofKorçë (southeast Albania) and north ofKonitsa andKastoria (northwestern Greece) at the west slopes ofGrammos mountain range.[4] A Byzantine military garrison under the same name was built west of Grammos.[5][6]
In a text byEmperor John VI Kantakouzenos (r. 1347-1354) whose 'History' covers the years 1320-1356, there is mention of localAlbanians; “While the emperor was spending about eight days in Achrida (Ohrid), the Albanian nomads living in the region of Deabolis (Devoll) appeared before him, as well as those from Koloneia (Kolonja) and those from the vicinity of Ohrid.” This meeting was estimated to have taken place at around February 1328.[10]
One source says that one of the two main waves of Albanian movements coming from the north entered Kolonjë in the 14th century, with the wave also affecting the neighboringDangëllia region.[11] The name Kolonja is related to theRoman period of the area.[12]
