What is francomania?

Francomania is an excessive admiration for French culture and things French, especially in fashion, language, and customs. It was particularly prevalent during the 18th century among some sections of the European upper classes.

For example, during the 18th century, many European aristocrats and intellectuals spoke French, read French literature, and imitated French fashions and manners. This was due to the prestige and influence of French culture at the time. France was widely regarded as the centre of fashion, art, and philosophy.
