What was the German confederation made up of?

The German Confederation, established in 1815 after the Congress of Vienna, was composed of 39 German states, including major entities like Prussia and Austria, along with smaller principalities and free cities. It served as a loose political association aimed at coordinating the member states' economic and military policies while preserving their individual sovereignty. The Confederation ultimately faced challenges in promoting unity, leading to its dissolution in 1866 following the Austro-Prussian War.
