Even reading the Wikipedia article "Dark Ages" you can see the misuse of the term:
https://en.wikipedia.org/wiki/Dark_Ages_%28historiography%29In Roman Catholic Europe, all scholarship existed under the auspices of the Papal authority, and was conducted in entirely Catholic universities and monasteries, for better or worse. There were no "secular" schools. Many chronicles and histories and other documents remain extant which are written in Medieval Latin and accessible to only a few scholars having academic credentials and support. You just can't go to a bookstore and get a copy of Baronius or Petrarch.
There has been, in my opinion, a multifaceted disdain for the production of popular accounts of the history of the Middle Ages which has endured now for several centuries.
The first aspect is Protestant. The Reformation and the break away from Roman Catholic Church dominance of half of Europe created a distaste for anything belonging to the Catholic Church.
The second aspect is Jewish. As soon as the Jews were emancipated, Jewish capital (after the French Revolution) quickly gave Jewish interests a dominant position in media and publishing from that time forward. Since then a large portion of the histories we have available are focused on the periods of "enlightenment" and "renaissance", because the periods from the days of Constantine unto Napoleon were indeed a "dark age" for the Jews.
There is plenty of scholarly academic material concerning the Middle Ages, but I think the Jew has popularized the term "Dark Ages" in order to lead the average Christian to believe that nothing much is known about those "evil" times, which were actually only evil to the Jew. But the Middle Ages were also filled with Jewish treachery in the subversion of Christian Europe, and the Jews would never want us to realize that.
If an accurate study of the Middle Ages were popularized, Whites today would have a much higher racial awareness and there would be no "White guilt" that the Jews could possibly infect us with.
This is not a full discussion, but I thought I would offer a few of my opinions.
Because of the language barriers and the difficulty in reaching original source materials, scholarly books detailing life in the Middle Ages can be very expensive. Those that are available, I certainly would not know the value of because I could never afford to see them. Here is an example:

One of them is here, even though it is a Jesuit university and loaded with propaganda as well:
