Final answer:
A. France was neutral in the conflict
C. The Holy Roman Emperor had little influence in France
D. French support was not a significant factor in the war
French support for the Holy Roman Emperor was not a cause of the Thirty Years War because France was neutral, the Holy Roman Emperor had little influence in France, and French support was not a significant factor in the war.
Step-by-step explanation:
French support for the Holy Roman Emperor was not a cause of the Thirty Years War because:
- France was neutral in the conflict
- The Holy Roman Emperor had little influence in France
- French support was not a significant factor in the war
France joined the war on the side of the Protestants primarily to become the preeminent power in Europe, not to support the Holy Roman Emperor. The war was primarily fought within German lands, and French support did not have a significant impact on the outcome.
