"Iron Century" Series
The 10th century AD, broadly referring to the period from 980 to 1030 AD, was called the Iron Century by the 16th-century historian Caesar Baronius.

Most of them are CPs with no more than 5 people who have the same hobby in the world (I chose no CP for the article classification, because there are all kinds of sexual orientations, including friendship ones, and the focus is not on sexual orientation)
Mainly Central and Western Europe (How come the Five Dynasties and Ten Kingdoms are not considered the Iron Century?)
Intent: In the 10th century AD, kingdoms fell and kingdoms rose, and another period of historical change came after the end of Charlemagne's empire.
