Kruja in the context of "League of Lezhë"

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.

Gjin Progoni (Latin: Ginius) was an archon (or lord) of Kruja, located in present-day Albania, from c. 1198 until his death in 1208. He succeeded his father, Progon of Kruja, becoming the second ruler of the Principality of Arbanon. During his reign, he controlled the areas around Elbasan and the fortress of Krujë. He also maintained good ties with the Despotate of Epirus due to the Venetian threat in northern Epirus. Gjin was succeeded by his younger brother Dhimitër Progoni.

The Principality of Muzaka (Albanian: Principata e Muzakajve), also known as the Lordship of Berat, was an independent realm ruled by the Albanian Muzaka family with its capital at Berat, covering territories in Central and Southern Albania, Western Macedonia and Northern Greece. One of the first rulers was Andrea I Muzaka whose reign was recognized by the Byzantine Emperor. During the Battle of Savra, the Ottomans captured Berat from Balša II, together with Kruja and Ulcinj. They soon retreated from all of those towns keeping only Castoria under their permanent control. Some sources explain that Ottomans probably remained in Berat with intention to use it as foothold to capture Valona. By 1396 Muzaka family took over control of Berat. In 1417 the territories of the Principality, including Vlorë and Berat, became a part of the Ottoman Empire.
