Which describes a result of the thirty years war

"Initially a war between various Protestant and Catholic states in the fragmented Holy Roman Empire, it gradually developed into a more general conflict involving most of the great powers. These states employed relatively large mercenary armies, and the war became less about religion and more of a continuation of the France-Habsburg rivalry for European political pre-eminence. In the 17th century, religious beliefs and practices were a much larger influence on an average European than they are today. During that era, almost everyone was vested on one side of the dispute or another, which was also closely tied to people's ethnicities and loyalties, as religious beliefs affected ideas of the legitimacy of the political status of rulers. The war began when the newly elected Holy Roman Emperor, Ferdinand II, tried to impose religious uniformity on his domains, forcing Roman Catholicism on its peoples. The northern Protestant states, angered by the violation of their rights to choose that had been granted in the Peace of Augsburg, banded together to form the Protestant Union. Ferdinand II was a devout Roman Catholic and relatively intolerant when compared to his predecessor, Rudolf II. His policies were considered strongly pro-Catholic."
