Of Skyrim.

Countries are inventions of man (or let's say "mortals" in this case). Thier boaders exist only where people choose to put them, and who says otherwise. The Reach is directly next to Highrock, and was not always a part of Skyrim. The Reachmen lived there, as a part of High Rock, until Tiber Septim came and conqured them for the King of Falkreath, in which it was added to his rule, and later to Skyrim.

The Reach was part of High Rock until it was taken from them.
