 After World War I, Alsace along with the diocese was returned to France, but the status from the concordat has been preserved since as part of the Local law in Alsace-Moselle.The diocese was elevated to Archdiocese of Strasbourg on 1 June 1988 by Pope John Paul II but not as Metropolitan of an ecclesiastical province and remains exempt, so having nor being a suffragan.The bishop of this see is appointed by the French president according to the Concordat of 1801.
