Etiquette in Europe is not uniform. Even within the regions of Europe, etiquette may not be uniform: within a single country there may be differences in customs, especially where there are different linguistic groups, as in Switzerland where there are French, German and Italian speakers.[1]
Despite this heterogeneity, many points of etiquette have spread through Europe and many features are shared. The ancient Roman Empire is a historical source, and the cosmopolitan royalty and also nobility were effective in spreading etiquette throughout Europe. For example, in the Palace of Versailles, where French nobility was concentrated, a complicated etiquette was developed.
