Tosk in the context of "Myzeqe"

Arbanon (Old Gheg: Arbënia, Old Tosk: Arbëria; Latin: Arbanum) was a medieval principality in present-day Albania, ruled by the native Progoni family, and the first Albanian state to emerge in recorded history. The principality was established in 1190 by the Albanian archon Progon in the region surrounding Kruja, to the east and northeast of Venetian territories. Progon was succeeded by his sons Gjin and then Demetrius, who managed to retain a considerable degree of autonomy from the Byzantine Empire. In 1204, Arbanon attained full, though temporary, political independence, taking advantage of the weakening of Constantinople following its pillage during the Fourth Crusade. However, Arbanon lost its large autonomy c. 1216, when the ruler of Epirus, Michael I Komnenos Doukas, started an invasion northward into Albania and Macedonia, taking Kruja and ending the independence of the principality. From this year, after the death of Demetrius, the last ruler of the Progoni family, Arbanon was successively controlled by the Despotate of Epirus, then by the Bulgarian Empire and, from 1235, by the Empire of Nicaea.

During this period, the area was ruled by the Greco-Albanian lord Gregorios Kamonas, the new spouse of Demetrius' Serbian former wife Komnena Nemanjić, and by Golem (Gulam), a local magnate who had married Kamonas' and Komnena's daughter. Arbanon was eventually annexed in the winter of 1256–57 by the Byzantine statesman George Akropolites. Golem subsequently disappeared from historical records. Akropolites' historical writings are the main primary source for late Arbanon and its history.

Cham Albanians or Chams (also spelled Çam Albanians or Çams; Albanian: Çamët; Greek: Τσάμηδες, romanized: Tsámides), are a subgroup of Albanians who originally resided in a region along the coast of the Ionian Sea in southwestern Albania and northwestern Greece, an area known among Albanians as Chameria. The Chams have their own particular cultural identity within Albanian subgroups. A number of Chams contributed to the Albanian national identity and played an important role in starting the renaissance of the Albanian culture in the 19th century. The Chams speak their own dialect of the Albanian language, the Cham Albanian dialect, which is a Southern Tosk Albanian dialect and one of the two most conservative ones; the other being Arvanitika.

During the late 1930s Chams suffered from intimidation and persecution under the dictatorship of General Metaxas. Following the Italian occupation of Albania in 1939, the Chams became a prominent propaganda tool for the Italians and irredentist elements among them became more vocal. As a result, on the eve of the Greco-Italian War, Greek authorities deported the adult male Cham population to internment camps. After the occupation of Greece, parts of the Muslim Cham population collaborated with Italian and German forces. This fueled resentment among the local Greek population and in the aftermath of World War II, the entire Muslim Cham population were forcefully expelled to Albania.
