A new Catholic aristocracy of the Thirty Years War initiated the rise of new local cultural centres possessing strong political and economic autonomy, which reflected the absolutist status of their rulers. The foreign noble soldiers formed an entirely new group of donators at this time. The traditional Bohemian nobility was active in administrative offices and focused on building spectacular city palaces in political centres [Vienna, Prague]. The officers of the Imperial army created private local residences as centres of their small regional domain, often situated in the border zone of the country. Research has not yet paid much attention to the patronage of these war conquistadors, with the exceptions of the generals Albrecht of Wallenstein and Rombaldo Collalto. Wallenstein's officers and his army rivals brought to Bohemia not just an aggressive policy but also proto-Baroque style in architecture and a new cultural orientation.
