Napoleons domination increased nationalism in other countries too.
Explanation:
Napoleon was a dynamic military strategist and his willingness to suffer any loss by taking up huge risks in his life time made him a fierce and an aggressive leader. He crushes his enemies and annexed many cities forcefully into France and this expanded his European empire.
Once he gained control over the kingdoms, he dethroned many monarchs and made his close relatives to occupy the throne. The news of his majestic march of arrival into a country itself posed threat and intimidation in the minds of the monarchs and they yielded in.
