In a word, metternich was a giant of conservatism at that time (19th century), and more than 30 years after the Vienna conference (18 15- 1848) was called "metternich era".

Clemens was hostile to the nation and liberalism, of course, because of his background, but on the other hand, because of the needs of the Austrian Empire itself. During the gathering of great powers, the Austrian emperor Francis I once said to a Russian envoy, "My country is like a house eaten by insects. No one knows how much it will collapse if it moves. "

In fact, the ethnic composition of Austria at that time was more complicated, including Hungarians, Czechs, Romanians, Italians, Southern Slavs and Poles. In other words, Austria has no national or cultural unity, so Medvedev is most afraid of the transmission of national independence and democratic political ideas. He believes that these forces are enough to make the Austrian Empire fall apart.

In any case, Clemens was an important diplomat in the history of19th century. He delineated the development of Europe in the early19th century, and maintained the autocratic rule of European autocratic countries for more than 30 years.
