In the Second ErSecond Era, Falkreath was part of the Colovian Estates meaning it was part of Colovia, thus Cyrodiil. (Source: The Arcturian Heresy)  As of the Third Era we know that Falkreath is part of Skyrim. (Source: The map in Oblivion)

So do we know anything about when, why and how this change occured? Is there some record of fights between Nords and Imperials or anything? This has been on my head for a while.
