"Event A happened. Event B happened. Event C happened. In that order. Perhaps that means X"
The pop-history tone is closer to:
"Historical character M had plans to N, inspired by O. This is supported by the evidence we have for events A, B and C."
There's no firm line between scholarly and pop history other than the reputation and credibility of the work, which often isn't obvious to lay readers.
That's both academic and pop-history, where a better representation would be "A gazillion different events happened but let's talk about events A, B, and C." It's impossible to talk about all the events that happened, so everyone needs to select the "important" ones. Of course when selecting what's "important" the bias is employed. It's not uncommon to reach different conclusions when looking at certain events (while disregarding others).
Consequently, if you're an author seeking to be absolutely fidelious to the known facts about some period of history somewhere, but nevertheless desire to spin a narrative from them, then frequently no matter what that narrative might be, you're crossing a line that many in academia don't think you should cross.
