Question

what was the primary aim behind creating the german confederation at the congress of vienna?
to promote revolutionary idealism

to establish dominance over france

to address tension in german states

Explanation:

The Congress of Vienna aimed to restore stability and order in Europe after the Napoleonic Wars. The German states had been fragmented and there were tensions among them. Creating the German Confederation was a way to address these internal tensions in the German - speaking areas. It was not about promoting revolutionary idealism (as the Congress was more about restoring the old order) and not primarily about establishing dominance over France (though balancing power was a concern, the direct aim for the German Confederation was internal German state relations).

Answer:

to address tension in German states
