Strictly speaking, the kingdoms established by Franks before 9 19 and many kingdoms established by Germans in the western Roman Empire during the great national migration should be called Germanic kingdoms or Germanic countries, and people living in this land should become Germanic. The kingdom, empire or country established after 9 19 should be called Germany, and its residents should be called Germans. 187 1 year, Germany was unified and the nation-state was born. The empire, * * * and the republic established from then on should be called Germany, and its citizens should be called Germans. 1867, Austria broke away from Germany and established the Austro-Hungarian Empire. After that Austria can't be called Germany, but it can still be called Germany.

So Germanic is a broad term, not only referring to Germans.
The following is a reference to the differences between Germans, Germans and Germans.
