The schools are approximately 4.9 mi away and were basically separated by Westerville Road.
Once that was no longer happening, in 2014 at the end of the season they played Whetstone, which isn't considered a “rivalry,” but is Mifflin's City League North foe.
Mifflin developed a lot of rivalries within their division which include Beechcroft High School and Northland High School which are predominantly played in the middle of the season back to back.
The reason why it's named this is because usually whoever ends up winning each “Battle” is crowned the “King” of the City League North.
