Bourgeois nationalism is a term from Marxist phraseology. It refers to the practice of dividing people by nationality, race, ethnicity, or religion, in order to make them hate (and possibly fight) each other. It is seen as a divide and conquer strategy used by the ruling classes to prevent the working class from uniting against them (hence the Marxist slogan, Workers of all countries, unite!).
Nationalism is not an innately bourgeois phenomenon: in the colonial and semi-colonial countries the national struggle is engaged in by workers and peasants as well as the conventional 'rising bourgeoisie', and workers and peasants can, under the right circumstances and with the right politics and tactics, take the lead.
It is a fairly direct deduction from Lenin's theory of nationalism to argue as follows: the overall force of superexploitation in colonies and semi-colonies, and its attendant political force, national oppression, is the basic, underlying cause of the rise of national movements in these sorts of areas.
Within national communist parties ofadvanced countries, I suspect that the Luxemburgian view was rather powerful, and must have had something to do with the far from proud record of some of these parties in the matter of the liberation of 'their own' colonies.

By Soviet definition, national cultures were to be "socialist by content and national by form", to be used to promote the official aims and values of the state.
In practice, Russian national culture and language were promoted, especially during and after World War II, while Ukrainian, Georgian, Armenian, Lithuanian, Jewish (see Yevsektsiya) and other national movements and cultures were suppressed and their leaders purged.
