 It is important to note a distinction between cultural heritage and national heritage. As the discussions of official heritage and difficult heritage reveal, heritage can play an influential role in cultivating a sense of national identity around a national culture (Ireland &amp; Schofield 2015: 2; Weiss 2007). However, it is important not to conflate the idea of a national culture with the empirically false claim that nations are culturally homogeneous: indeed, the intranational diversity of cultures is the fact from which the political problem of multiculturalism arises (see entry on  multiculturalism).  There is of course significant cultural diversity in cultural groupings of many kinds, nationalistic or not. This topic is discussed further in  section 2.2.
