The politics of Super Mario Bros APR 09 2013
Quora is full of questions college students ask each other while high, except that sometimes they get answered seriously. Case in point: What is the political situation in the Mario universe? The top answer starts out:
Without going into too much detail, Mario generally lives and works in the Mushroom Kingdom, one of the largest geo-political structures on Mushroom World, in the Grand Finale Galaxy in, yes, the Mushroom Universe.
For the purposes of this answer I will deliberately restrict the terms to discussing Mushroom World, as a comprehensive answer on the entire Mushroom Universe would require covering 20-22 (depending on how you count) Galaxies and frankly, I doubt it would be any more fun to read than it would be to write.
Also, Bowser is probably a fascist.
