Remember Harold, we went over that, and agreeded it still didn't make sense, for multiple reasons. The time before High King Harald was not very big, and I assume decently recorded (he did get into power pretty early on), and founded the Kingdom of Skyrim, at that time they conquered other provinces, like High Rock and Morrowind, not the other way around (not denying that they were ever conquered, it just wasn't at that time).
