 From 1982 to 2016, Alsace was the smallest administrative "région" in metropolitan France, consisting of the Bas-Rhin and Haut-Rhin departments.Territorial reform passed by the French legislature in 2014 resulted in the merger of the Alsace administrative region with Champagne-Ardenne and Lorraine to form Grand Est.Due to protests it was decided in 2019 that Bas-Rhin and Haut-Rhin would form the future European Collectivity of Alsace in 2021.
