Karl Thopia in the context of "Ottoman wars in Europe"

The Kingdom of Albania (Albanian: Mbretëria e Arbërisë, Latin: Regnum Albaniæ) was established by Charles of Anjou in the Albanian territories he conquered from the Byzantine Empire in 1271, with the help of the local Albanian nobility. The Kingdom of Albania was declared in late February 1272. The kingdom extended from the region of Durazzo (Dyrrhachium, modern Durrës) south along the coast to Butrint. A major attempt to advance further in direction of Constantinople failed at the Siege of Berat (1280–1281). A Byzantine counteroffensive soon ensued, which drove the Angevins out of the interior by 1281. The Sicilian Vespers further weakened the position of Charles, and the Kingdom was soon reduced by the Byzantines to a small area around Durazzo. The Angevins held out here, however, until 1368, when the city was captured by Karl Thopia. In 1392, Karl Thopia's son surrendered the city to the Republic of Venice.

The Principality of Albania (Albanian: Principata e Arbërisë) was an Albanian principality ruled by the Albanian dynasty of Thopia. The first notable ruler was Tanusio Thopia, who became Count of Mat in 1328. The principality would reach its zenith during the rule of Karl Thopia, who emerged in 1359 after the Battle of Achelous, conquering the cities of Durrës and Krujë and consolidating his rule of central Albania between the rivers of Mat and Shkumbin. The principality would last up until 1415, when it was conquered by the Ottoman Empire.

Ottoman Albania was a period in Albanian history within the Ottoman Empire, from the Ottoman conquest in the late 15th century to the Albanian declaration of Independence and official secession from the Ottoman Empire in 1912. The Ottomans first entered Albania in 1385 upon the invitation of the Albanian noble Karl Thopia to suppress the forces of the noble Balša II during the Battle of Savra. They had some previous influence in some Albanian regions after the battle of Savra in 1385 but not direct control. The Ottomans placed garrisons throughout southern Albania by 1420s and established formal jurisdiction in central Albania by 1431. Even though The Ottomans claimed rule of all Albanian lands, most Albanian ethnic territories were still governed by medieval Albanian nobility who were free of Ottoman rule. The Sanjak of Albania was established in 1420 or 1430 controlling mostly central Albania, while Ottoman rule became more consolidated in 1481, after the fall of Shkodra and League of Lezhe with the country (including areas of today's Kosovo, Montenegro and Macedonia) being mostly free in the period of 1443–1481. Albanians revolted again in 1481 but the Ottomans finally controlled Albania by 1488.

The term used in Ottoman sources for the country was Arnavudluk (Ottoman Turkish: آرناوودلق), including areas such as present-day Albania, Kosovo, western North Macedonia, southern Serbia, southern Montenegro and parts of northern Greece.

The Battle of Achelous (Albanian: Beteja e Akelout) (also Battle of Acheloos) took place in 1358 or 1359 near the river Achelous in Aetolia, modern Greece, between the forces of the Despotate of Epirus under Nikephoros II Orsini and Albanian tribesmen under Karl Thopia. The Albanians defeated Orsini's troops and inflicted heavy casualties upon his forces, and Orsini himself was killed during the battle. Epirus was then divided amongst the Albanian clans, which resulted in the establishment of two despotates from regions previously part of the Despotate of Epirus: the Despotate of Arta and the Despotate of Angelokastron and Lepanto. Within Epirus, only the city of Ioannina remained under Greek governance and was not under the control of the Albanians.

The Battle of Savra (Albanian: Beteja e Savrës; Serbian: Bitka na Saurskom polju; Turkish: Savra Muharebesi; "Battle on the Saurian field") or the Battle of the Vjosë was fought on 18 September 1385 between Ottoman and much smaller Zetan forces, at the Savra field near Lushnjë (in modern-day southern Albania). The Ottomans were invited by Karl Thopia to support him in his feud against Balša II.

The King of Albania (Albanian: Mbreti i Shqipërisë) was a title styled by the official ruler of Albania. While the medieval Angevin Kingdom of Albania was a monarchy, it did not encompass the entirety of modern Albania. Although discontent among Albanian nobles emerged by 1282 due to the Angevin king's unfulfilled promises, the kingdom did not end at that time. Instead, Albanian nobles sought the support of the Roman Emperor in Constantinople, but Angevin rule continued in the region for several more decades. During the Middle Ages there have been many different Albanian nobles who called themselves ruler of Albania, including Dhimitër Progoni (Prince of the Albanians & Prince of Albania), Andrea II Muzaka (Despot of Albania), Karl Thopia (Prince of Albania), and Skanderbeg (Lord of Albania).

The modern Albania has been a kingdom on two occasions.
