Aalst suffered considerably under the Eighty Years' War (1568–1648). It was later taken by the French Marshal Turenne in the War of Devolution of 1667, then occupied by France until 1706, when it became independent once more following the Battle of Ramillies, along with Southern Flanders in general. The textile-based economy flourished under the French. In the 18th century, the Austrians controlled the region. 1830 saw Belgium gain independence and Aalst became part of the country, this ended a long period, starting in 1056, of foreign control, by such as the Spanish, German, French, and the Dutch. The 19th century was marked by social crises engendered by the Industrial Revolution, with Father Adolf Daens and his Christene Volkspartij emerging as the local defender of workers' rights. This was in response to "Rerum novarum", which established worker rights. However Daens felt this did not do enough. Eventually, he was made to pay for his "splinter movement". In the Pre-World War II years, the fascist movement in the Low Countries gained momentum, with the collaborationist "Vlaamsch Nationaal Verbond" (Flemish National Union) putting down roots in the region. Aalst, along with Brussels and Antwerp were the strongest subscribers to this line of thought. The 20th century was marked by bombardment and occupation by the Germans during both world wars.
