Why is "Albanian principalities" trending?

Wikipedia Overview

The term Albanian Principalities refers to a number of principalities created in the Middle Ages in Albania and the surrounding regions in the western Balkans that were ruled by Albanian nobility. The 12th century marked the first Albanian principality, the Principality of Arbanon. It was later, however, in the 2nd half of the 14th century that these principalities became stronger, especially with the fall of the Serbian Empire after 1355. Some of these principalities were notably united in 1444 under the military alliance called League of Lezhë up to 1480 which defeated the Ottoman Empire in more than 28 battles. They covered modern day Albania, western and central Kosovo, Epirus, areas up to Corinth, western North Macedonia, southern Montenegro. The leaders of these principalities were some of the most noted Balkan figures in the 14th and 15th centuries such as Gjin Bua Shpata, Andrea II Muzaka, Gjon Zenebishi, Karl Topia, Andrea Gropa, Balsha family, Gjergj Arianiti, Gjon Kastrioti, Skanderbeg, Dukagjini family and Lek Dukagjini.
