Basically how I see the government work in the Mushroom Kingdom. Note that there would be more Vassal Lords than shown here, and that the ones shown are just examples.Every one answers to the Supreme Ruler, which in fact the Mushroom King, but since he is crazy (see here on that theory: www.reddit.com/r/FanTheories/c… ), He is locked away and Peach serves in his place, thus keeping the title "Princess" while still being in charge. No one speaks of the somewhat embarrassing tragedy that is the Mushroom King, which is why no one mentions it.Next in line are the Vassal Lords of the Kingdom, whom are positioned in the land to govern their selected region (Koopa Kingdom, Kong Archipelago, Dinosaur Land, etc). Each vassal lord must care for their land and their people. Vassal Lords can call upon their bannermen, the Lesser Lords (King Bob-omb, the Kongs, Powerful Toads), which are next in line, to wage wars. Although Peach is the supreme ruler too, she probably has bannermen of her own, presumably with the Mario Bros somewhere along her ranks.The Lesser Lords swear allegiance to a Vassal Lord and when he then summons, the Lesser lords must answer with armies mustered. They are expected to keep the land functioning, as in making sure the commoners do their jobs. It is worth noting that currently, the lesser lords weigh in favor of Bowser, a direct result of the civil war before the events of the "story" of the Mario games, when the kingdom, led by Bowser's father, rebelled against the folly of the Mushroom King. While the rebellion was overthrown, the animosity towards the Mushroom Throne still holds today, as is evident in the games.Finally, the Commoners. They are the backbone of the land, all part of the larger, rather rickety machine that is the Mushroom Kingdom. They serve under a Lesser Lord, local leader if you will, and cares little for the play of power the kings run. The commoners are those who fight the wars, often with local folk heroes rising among them (see the Mario Bros.) Those who do not settle the land might make a living as adventurers or mercenaries. Commoners who make a name for themselves might strike luck and be appointed Landed Knights, who have right to own lands and castles of their own (Again, see the Mario Bros)Sort of based off of ASoIaF. Rather much so... Questions?
