Arbanon 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 (Dhimitër), 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 ca. 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.

Albania, officially the Republic of Albania, is a country in Southeast Europe. It is in the Balkans, on the Adriatic and Ionian Seas within the Mediterranean Sea, and shares land borders with Montenegro to the northwest, Kosovo to the northeast, North Macedonia to the east and Greece to the south. Spanning an area of 28,748 km2 (11,100 sq mi), it has a varied range of climatic, geological, hydrological and morphological conditions. Albania's landscapes range from rugged snow-capped mountains in the Albanian Alps and the Korab, Skanderbeg, Pindus and Ceraunian Mountains, to fertile lowland plains extending from the Adriatic and Ionian seacoasts. Tirana is the capital and largest city in the country, followed by Durrës, Vlorë, and Shkodër.
