 Until the mid 20th century, the Thirty Years War was primarily seen as a German religious conflict; in 1938, historian CV Wedgwood argued it formed part of a wider, ongoing European struggle, with the Habsburg-Bourbon conflict at its centre.A perspective now generally accepted by historians, its implication is that strategies pursued during the Franco-Spanish War can only be understood in a European context.In 1630, Habsburg possessions bordered France in the Spanish Netherlands, Franche-Comté, Alsace, Roussillon and Lorraine (see Map).
