Could you please provide more information? Auto-translated

Good afternoon!
I would like to finally get a clear understanding of the chronological order of the storylines in the Heroes games.
If anyone has found this information or figured it out, please provide a list in order. So that I can play through all of them and understand the story from beginning to end. ;)

There are two distinct "Heroes of Might and Magic" universes: before the fifth installment and after. Demilich has provided a good overview of the older universe's history. Search for "Demilich's chronology" on Google, and you'll find it.

I searched, and it just provides the history, not which game to play and how.
I would like to know the best order to play them in.

Might and Magic 1-5
Heroes of Might and Magic 1-2
Might and Magic 6
Heroes of Might and Magic 3
Might and Magic 7-8
Might and Magic 9
Heroes of Might and Magic 4

In the case of the third Heroes game, there are a couple of nuances, as the events of some of the expansions take place after the seventh Might and Magic game, and some before.
The last two games can be played in any order; their storylines are not connected in any way.
If you are only interested in the history of Enroth, you can skip Might and Magic 1-5 (the games take place on other planets, but there are some small references in the following games) and the last two (they also take place on a different planet, but there are some characters from Enroth).
