Catholic renewal and the Council of Trent answered Protestant challenges; rulers, cities, and subjects negotiated or fought over doctrine, property, and authority.

Historical significance
The Reformation transformed worship, education, print culture, family life, and relations between churches and governments. Its confessional divisions helped frame the Thirty Years' War, but that later conflict also grew from the Holy Roman Empire's constitutional tensions, dynastic rivalry, and competition among European powers; religion alone does not explain it.
