In 1489 Prince-Archbishop Leonhard von Keutschach in 1489 acquired a large brewery, whereafter the sale of Hofbräu Kaltenhausen beers became another main source of revenue for the Salzburg archbishopric. At the end of the 17th century, Prince-Archbishop Kuenburg had the Protestant miners expelled, after which several hundred of them emigrated to Walcheren and Zeelandic Flanders in the Dutch Republic. With the former prince-archbishopric, Hallein became part of the Austrian Empire by 1816.
