Sweden secured territorial gains in Pomerania and Bremen in Northern Germany, attaining great power status in the Baltic. The Habsburg Dynasty lost its absolute authority within the Empire and was forced to grant autonomy to principalities like Bavaria and Saxony. The Spanish Habsburgs had to recognize Dutch independence and cede European supremacy to France.
