Alsace under the crown of France after 1648
After 1648 the royal administration of France sets itself up in a devastated region and in the depopulated areas. Alsace experience a strong wave of immigrations from Switzerland, the Savoy and regions further away.An age of demographic, economic, political and cultural transformations begins. This occurs around the headquarters of administration (which is located first in Breisach and then in Strasbourg) as well as the sovereign council which is created in 1657 and established in January 1658 in Ensisheim. In 1673, Colmar submits to the rule of the king, and in 1686, in this former bastion of opposition to royal rule, an administrator is installed as representative of royal power over the venerable institutions of the city. In 1681 accedes totally after a brief demonstration of power, thus following the example of Colmar. The Alsace is now united. Louis XIV has achieved what the archdukes, especially Leopold V, had failed to do.In the 18th century begins a golden age for the Alsace in many respects.
