In the 19th century Limoges saw strong construction activity, which included the destruction and rebuilding of much of the city centre. The unsafe conditions of the poorer population is highlighted by the outbreak of several riots, including that of July–November 1830 and April 1848. The first French confederation of workers, Confédération Générale du Travail (CGT) (General Confederation of Labour), was created in Limoges in 1895.
