In the 15th century there was no Cluj, the city was hungarian-german and called Kolozsvár. In the 15th century, Transylvania only had a 20-22% romanian population, and very few of them lived in cities.
To my understanding, Kolosvár is the county that the city was located in. This city was called Cluj by Romanians, Kolozsvár by Hungarians, and Klausenburg by Germans. There is no precise date for when the city switched its name from German (its first name) to any others, so I used its Romanian name, given the fact that Transylvania is today located in Romania. Thanks.
