Holy Roman empire. or is it?

The Holy Roman Empire (HRE) was a German unity of mostly small nations led by one which was the emperor. The nations have a lot of autonomy and the emperor didn't possess much power outside of his home country. The HRE was established in 962 CE but had its golden era in the Enlightenment period. The HRE aimed to be the heirs to the Roman empire but with God as their guide. However a man called Voltaire disliked the name and the whole idea. His famous quote stated that the Holy Roman Empire was neither Holy nor Roman and not even an Empire.
