Albanian nationalism is a general grouping of nationalist ideas and concepts generated by ethnic Albanians that were first formed in the 19th century during the Albanian National Awakening (Albanian: Rilindja). Albanian nationalism is also associated with similar concepts, such as Albanianism ("Shqiptaria") and Pan-Albanianism, that includes ideas on the creation of a geographically expanded Albanian state or a Greater Albania encompassing adjacent Balkan lands with substantial Albanian populations.
The onset of the Great Eastern Crisis (1875–1878), which threatened the partition of Albanian-inhabited lands of the Balkans by neighbouring Orthodox Christian states, stimulated the emergence of the Albanian National Awakening and the nationalist movement. During the 19th century, some Western scholarly influences, Albanian diaspora groups such as the Arbëresh and Albanian National Awakening figures contributed greatly to spreading influences and ideas among the Balkan Albanians, within the context of Albanian self-determination. Among those were ideas of an Illyrian contribution to Albanian ethnogenesis, which still dominate Albanian nationalism in contemporary times. The idea of Illyrian-Albanian continuity is the founding myth of the Albanian nation. Other ancient peoples are also claimed as ancestors, in particular the Epirotes and the Pelasgians. These national myths are important in order to geopolitically support claims of autochthony in Greater Albania (most importantly in Kosovo and North Macedonia).
