In the Middle Ages, the seigniory of Riquewihr consisted of the villages of Hunawihr, Beblenheim, Mittelwihr, Ostheim, and the extinct localities of Altenheim and Regenhausen. In 1489, Riquewihr became the capital and the administrative, judicial, and religious center of the possessions of Württemberg. It introduced a prosperous era for the city. The flourishing wine trade was exported throughout the Empire and the Hanseatic countries and brought opulence. During the Thirty Years' War (1618-1648), the armies swept over Alsace and devastated it. Famine and epidemics also profoundly impacted the region, whose 50% of the population died.
