There is no such as conservatism in Europe. All Europe politics reside in a narrow band that straddles fascism on the right and communism on the left. There is no such thing as individualism in Europe.
They are unified in politics, so parties differentiate themselves between traditionalism, the old life, and progressivism, the new life.
The fascists are not on the Right, they are on the Left....no matter how much Leftists lie and try to claim that they are on the Right.
Mussolini and Hitler were both men of the Left. Both very much believed in socialism. The only real difference is they were willing to let business owners/managers stay in place to run the businesses - so long as those businesses did what the state wanted.
What some Americans think defines conservatism is mostly a US - specific idea these days, that’s true. In traditional European thinking this was thought of as an English thing, not American. This was what “liberal” originally meant.
Liberalism in the old sense was a 19th century idea deriving from the industrial revolution and mercantile Britain. Continental Europe did some of that in its Anglophilic episodes, but its rather unnatural to them.
European conservatism is indeed traditionalism. De Maistre is your man for that.
