Product Story Introduction:
I think the title "Count" is the most common name for everyone, because it often appears in classic literary works, such as "The Count of Monte Cristo", "Dracula" and "Four Hundred Years".
Count "earl" is also a member of the nobility, a title of Anglo-Saxon origin, which also means "jarl" ("chief") in Scandinavian.
In early Scandinavia, it mainly referred to a chief who ruled a territory, but it could also refer to a prince who held land sovereignty. For example, the rulers of several small Norwegian kingdoms have the title "jarl" and in many cases have as much power as their neighboring monarchs who hold the title of king.
In Anglo-Saxon England, earls also own land under their jurisdiction and have the right to be tried in magistrates authorized by the king. They would collect fines and taxes for the king, and in return the earl would receive "one-third" of the income.
Therefore, the original function of the earl is actually similar to that of the royal governor. Although sometimes the title of the earl is nominally equivalent to the duke of the mainland, the obvious difference with them is that the earl itself is not the real ruler.
