Albanians are an ethnic group and nation native to the Balkan Peninsula who share a common Albanian ancestry, culture, history and language. They are the main ethnic group of Albania and Kosovo, and they also live in the neighboring countries of North Macedonia, Montenegro, Greece, and Serbia, as well as in Italy, Croatia, Bulgaria, and Turkey. Albanians also constitute a large diaspora with several communities established across Europe and other continents.

The language of the Albanians is an Indo-European language and the only surviving representative of the Albanoid branch, which belongs to the Paleo-Balkan group. Albanians have a western Paleo-Balkanic origin, and, for geographic and historical reasons, most scholars maintain that they descend at least partially from the Illyrians, but the question of which other Paleo-Balkan group(s) contributed to the ethnogenesis of the Albanians is still a subject of academic debate.

The first mention of the ethnonym Albanoi occurred in the 2nd century AD by Ptolemy describing an Illyrian tribe who lived around present-day central Albania. The first certain reference to Albanians as an ethnic group comes from 11th-century chronicler Michael Attaleiates who describes them as living in the theme of Dyrrhachium.

The Shkumbin River roughly demarcates the Albanian language between Gheg and Tosk dialects. Christianity in Albania was under the jurisdiction of the Bishop of Rome until the 8th century AD. Then, dioceses in Albania were transferred to the patriarchate of Constantinople. In 1054, after the Great Schism, the north gradually became identified with Roman Catholicism and the south with Eastern Orthodoxy. In 1190 Albanians established the Principality of Arbanon in central Albania with the capital in Krujë.

The Albanian diaspora has its roots in migration from the Middle Ages initially across Southern Europe and eventually across wider Europe and the New World. Between the 13th and 18th centuries, sizeable numbers migrated to escape various social, economic or political difficulties. Albanian population groups settled in Southern Greece between the 13th and 18th centuries and came to be known as Arvanites. Other Albanian population groups settled across Southern Italy and Sicily between the 11th and 18th centuries and came to be known as Arbëreshë. Albanians have also migrated to Romania since the late 16th century. In the 18th century smaller Albanian population groups settled in Southern Croatia (who came to be known as Arbanasi), and pockets of Southern Ukraine.. "We can say that all in some way belong to a kind of ethnic category, and often more than one. As an example, I cite the case of Zadar Arbanasi. To understand the problem of the Albanians and their ethnolinguistic (ethnic and linguistic) identity, it is necessary to go into the history of their immigration that goes back to the beginning of the 18th century., etc more precisely: the period from the first migration of 1726, the period of the second migration of 1733, and until 1754, which is considered to be the final year of their immigration. All they moved from three villages from the area of Lake Scutari – Briska, Šestan and Livara. Fleeing from the Ottomans, plague and other troubles, the general provider Nicola Erizzo II allowed them to settle in the area of today's Arbanasa and Zemunik. One part of the population in Zemunik became assimilated with the local population, forgetting their language. These are for example, today's Prenda, Šestani, Ćurkovići, Paleke etc. The second part of the population tried to maintain their ethnic and linguistic identity during these 280 years. On 10 May 2006 marked the 280th anniversary of their arrival in the suburb of Zadar. It was not easy, especially in the beginning, because they did not have their own church, school, etc., and is the only way to maintain their identity and language was verbally.". "Historical Facts. Four villages with Albanian population are located in the Ukraine: Karakurt (Zhovtnevoe) set up in 1811 (Odessa region), Tyushki (Georgievka), Dzhandran (Gammovka) and Taz (Devninskoe) set up in 1862 (Zaporizh’a region). Before migrating to the territory of the Russian empire, Albanians had moved from the south-east of the present day Albania into Bulgaria (Varna region) because of the Osmanli invasion (Державин, 1914, 1926, 1933, 1948, pp. 156–169). Three hundred years later they had moved from Bulgaria to the Russian empire on account of Turkish-Russian opposition in the Balkan Peninsula. Ethnic Albanians also live in Moldova, Odessa and St. Petersburg. Present Day Situation. Nowadays, in the Ukraine and Russia there are an estimated 5000 ethnic Albanians. They live mainly in villages situated in the Odessa and Zaporizh’a regions. The language and many elements of traditional culture are still preserved and maintained in four Albanian villages (Будина, 2000, pp. 239–255; Иванова, 2000, pp. 40–53). From the ethnolinguistic and linguistic point of view these Albanian villages are of particular interest and value since they are excellent examples of a "melting pot" (Иванова, 1995, 1999). Bulgarians and Gagauzes live side by side with Albanians in Karakurt; Russians and Ukrainians share the same space with Albanians in the Azov Sea region. It is worth mentioning that in these multi-lingual environments, the Albanian patois retains original Balkan features."

By the 15th century, the expanding Ottoman Empire overpowered the Balkan Peninsula, but faced successful rebellion and resistance by the League of Lezhë, a union of Albanian principalities led by Gjergj Kastrioti Skanderbeg. By the 17th and 18th centuries, a substantial number of Albanians converted to Islam, which offered them equal opportunities and advancement within the Ottoman Empire.; ; ; ; ; . Thereafter, Albanians attained significant positions and culturally contributed to the broader Muslim world. Innumerable officials and soldiers of the Ottoman State were of Albanian origin, including more than 40 Grand Viziers, and under the Köprülü, in particular, the Ottoman Empire reached its greatest territorial extension. Between the second half of the 18th century and the first half of the 19th century Albanian Pashaliks were established by Kara Mahmud pasha of Scutari, Ali pasha of Yanina, and Ahmet Kurt pasha of Berat, while the Albanian wālī Muhammad Ali established a dynasty that ruled over Egypt and Sudan until the middle of the 20th century, a period in which Albanians formed a substantial community in Egypt.

During the 19th century, cultural developments, widely attributed to Albanians having gathered both spiritual and intellectual strength, conclusively led to the Albanian Renaissance. In 1912 during the Balkan Wars, Albanians declared the independence of their country. The demarcation of the new Albanian state was established following the Treaty of Bucharest and left about half of the ethnic Albanian population outside of its borders, partitioned between Greece, Montenegro and Serbia. After the Second World War up until the Revolutions of 1991, Albania was governed by a communist government under Enver Hoxha where Albania became largely isolated from the rest of Europe. In neighbouring Yugoslavia, Albanians underwent periods of discrimination and systematic oppression that concluded with the War of Kosovo and eventually with Kosovar independence.

Ethnonym

The Albanians () and their country Albania () have been identified by many ethnonyms. The most common native ethnonym is "Shqiptar", plural "Shqiptarë"; the name "Albanians" (Byzantine Greek: Albanoi/Arbanitai/Arbanites; Latin: Albanenses/Arbanenses) was used in medieval documents and gradually entered European Languages from which other similar derivative names emerged, many of which were or still are in use, such as English "Albanians"; Italian "Albanesi"; German "Albaner"; Greek "Arvanites", "Alvanitis" (Αλβανίτης) plural: "Alvanites" (Αλβανίτες), "Alvanos" (Αλβανός) plural: "Alvanoi" (Αλβανοί); Turkish "Arnaut", "Arnavut"; South Slavic languages "Arbanasi" (Арбанаси), "Albanci" (Албанци); Aromanian "Arbinesh" and so on.

The term "Albanoi" (Αλβανοί) is first encountered on the works of Ptolemy (2nd century CE) also is encountered twice in the works of Byzantine historian Michael Attaliates, and the term "Arvanitai" (Αρβανίται) is used once by the same author. He referred to the "Albanoi" as having taken part in a revolt against the Byzantine Empire in 1043, and to the "Arbanitai" as subjects of the Duke of Dyrrachium (modern Durrës). These references have been disputed as to whether they refer to the people of Albania.. "It is still disputed by scholars that those Albanoi from 1042 were Normans from Sicily, [Southern Italy], or if they are in fact the Albanoi [a large clan of that belongs to the many clans of Albanians] found in Albanian lands during this time frame.". Historian E. Vranoussi believes that these "Albanoi" were Normans from Sicily. She also notes that the same term (as "Albani") in medieval Latin meant "foreigners".Vranoussi Erasmia, "The terms Albanoi and Arvanitai and the first mention of the homonym people of the Balkans in the 11th century sources", Balkanika Symmikta, 1970, 2, p. 207 – 228. For the meanings of Albanus, Albani, Albains etc., see pp 226–228, with footnotes to the lexicons Du Gange, Glossarium mediae el infimae Latinitatis, edition 1883, vol. 1, pp. 162 – 163, J. Niermeyer, Mediae Latinitatis Lexicon minus, Leiden 1960, pp. 32 – 33 and others. In Greek language.

The reference to "Arvanitai" from Attaliates regarding the participation of Albanians in a rebellion around 1078 is undisputed.. "It was supposed that those Albanoi from 1042 were Normans from Sicily, called by an archaic name (the Albanoi were an independent tribe from Southern Italy). The following instance is indisputable. It comes from the same Attaliates, who wrote that the Albanians (Arbanitai) were involved in the 1078; rebellion of..." In later Byzantine usage, the terms "Arbanitai" and "Albanoi" with a range of variants were used interchangeably, while sometimes the same groups were also called by the classicising name Illyrians.Mazaris 1975, pp. 76–79.N. Gregoras (ed. Bonn) V, 6; XI, 6.. The first reference to the Albanian language dates to the latter 13th century (around 1285).
