In 1800 the arrondissements of Metz, Briey, Sarreguemines and Thionville were established. In 1871 most of the department was ceded to Germany, except the arrondissement of Briey that joined the new department Meurthe-et-Moselle. In 1919 the department of Moselle was restored, with the arrondissements of Metz-Ville, Metz-Campagne, Boulay-Moselle, Château-Salins, Forbach, Sarrebourg, Sarreguemines, Thionville-Est and Thionville-Ouest. In January 2000 the canton of Sarralbe passed from the arrondissement of Forbach to the arrondissement of Sarreguemines.[4]
In January 2015 the arrondissements of Forbach and Boulay-Moselle were merged into the new arrondissement of the arrondissements of Forbach-Boulay-Moselle, the arrondissements of Metz-Campagne and Metz-Ville were merged into the new arrondissement of Metz and the arrondissements of Thionville-Est and Thionville-Ouest were merged into the new arrondissement of Thionville. In January 2016 the arrondissements of Sarrebourg and Château-Salins were merged into the new arrondissement of Sarrebourg-Château-Salins.[5]
