What was the impact of the thirty years war on germany and france answers?

The Thirty Years' War rearranged the previous structure of power. The conflict made Spain's military and political decline visible. While Spain was preoccupied with fighting in France, Portugal—which had been under Spanish control for 60 years (since 1580)—declared itself independent in 1640. The House of Braganza became the new dynasty of Portugal, beginning with King John IV. Meanwhile, Spain was finally forced to accept the independence of the Dutch Republic in 1648, ending the Eighty Years' War. With Spain weakening and Germany fractured and bled dry, France became the dominant power in Europe.
