in 1038–40. The second use of the term Albanoi is related to groups which supported the revolt of George Maniakes in 1042 and marched with him throughout the Balkans against the Byzantine capital, Constantinople. The term Arvanitai is used to describe a revolt of Bulgarians (Boulgaroi) and Arbanitai in the theme of Dyrrhachium in 1078–79. It is generally accepted that Arbanitai refers to the ethnonym of medieval Albanians. As such, it is considered to be the first attestation of Albanians as an ethnic group in Byzantine historiography. The use of the term Albanoi in 1038–49 and 1042 as an ethnonym related to Albanians have been a subject of debate. In what has been termed the "Vranoussi-Ducellier debate", Alain Ducellier proposed that both uses of the term referred to medieval Albanians. Era Vranoussi counter-suggested that the first use referred to Normans, while the second didn't have an ethnic connotation necessarily and could be a reference to the Normans as "foreigners" (aubain) in Epirus which Maniakes and his army traversed. This debate has never been resolved. A newer synthesis about the second use of the term Albanoi by Pëllumb Xhufi suggests that the term Albanoi may have referred to Albanians of the specific district of Arbanon, while Arbanitai to Albanians in general regardless of the specific region they inhabited. Language The majority of the Albanian people speak the Albanian language which is an independent branch within the Indo-European family of languages. It is a language isolate to any other known living language in Europe and indeed no other language in the world has been conclusively associated to its branch. Its origin remains conclusively unknown but it is believed it has descended from an ancient Paleo-Balkan language. The Albanian language is spoken by approximately 5 million people throughout the Balkan Peninsula as well as by a more substantial number by communities around the Americas, Europe and Oceania. Numerous variants and dialects of Albanian are used as an official language in Albania, Kosovo and North Macedonia. The language is also spoken in other countries whence it is officially recognised as a minority language in such countries as Croatia, Italy, Montenegro, Romania and Serbia. There are two principal dialects of the Albanian language traditionally represented by Gheg and Tosk. The ethnogeographical dividing line is traditionally considered to be the Shkumbin with Gheg spoken in the north of it and Tosk in the south. Dialects spoken
