There are also many cases known of trade with cloth materials and various craftsmanship and artistic products. Permanent connections of Prizren with Dalmatic, Italian and Albanian coastline cities, not only brought benefits to the city in economic aspect, but they also had their influence on transposing the reciprocal impacts in the field of culture, especially in figurative arts, in medicine, pharmacy and literature. As a result of the proximity with Novo-Brdo, within a short time, Pristina turned into a trading center. During the first half of the 14th century, the number of Raguzans kept increasing. Moreover, in Pristina there were also settled traders from Split and Zadar and as well as traders from Ulcinj and Turkey. From a general observation of the geographical area, and of the economic and political life, it is found that the primary inter-provincial links in the territories inhabited by Albanians would pursue the horizontal directions (west-east), and three economic zones were formed: Upper Albania, Middle Albania and Lower Albania, which had their own trade route system. "There were four important trade routes going through Upper Albania, which linked the coastline with the eastern territories:"  "Two important trade routes went through Middle Albania:"  "In a horizontal plane, several roads were going through Lower Albania:"   Besides the above described routes, the ethnic Albanian territories were pervaded in vertical line by other trade routes. One used to go along the sea coastline territories, which were even better connected between them through the sea routes. Whereas the best trade route in horizontal line was going through the territories of eastern Albania and it used to connect important centers like: Nish, Skopje, Manastir, Kostur, Janina, etc. This route, along with Egnacia road and with many of their branches, must have played a primary role in homogenizing the ethno-cultural features of Albanians and on expansion of the medieval national name known as Arber (Arberi, Albani). The provinces of Middle and Upper Albania were linked with each other also with other routes going through vertical line, along the valley of Drin river etc.
