When the districts were created on 24 February 1843, Luxembourg was one of the three of the country.

On 30 May 1857, the Mersch canton was taken from the Luxembourg district to made part of the new district of Mersch. on 4 May 1867, the new district was abolished and the Mersch canton was made again a part of the Luxembourg district.

On 2012, the communes of Bascharage and Clemency were combined to make the new commune of Käerjeng. So the number of communes changed from 47 to 46.

After the reorganization of Luxembourg's administrative divisions in 2015, all three districts were abolished per 3 October 2015.
