The Mushroom Kingdom is a fictional nation from Super Mario Series. It located in Central Europe, having a border with Germany, France, Italy, Belgium, Czech Republic, Austria and Slovenia.

Government
The government of the Mushroom Kingdom may seem simple, but it is in fact extremely complex and much more confusing than it first seems.

First and foremost, the present-day Mushroom Kingdom is not a true monarchy, on which a king or queen rules, but is in fact a principality, in which a prince or princess is the true ruler of the kingdom. Mushroom Kingdom residents incorrectly call their government a Monarchy anyway. When Peach dies, however, and the next in line takes over, they may choose to assume the title of King/Queen or be the next Prince/Princess. If the latter is the case, the Mushroom Kingdom would once again be a Monarchy.

The sovereign head of state is the reigning monarch. In the case of modern times, that would be Princess Peach Toadstool.

As ruler, the leader has near-absolute power and can do almost anything, though the kings and queens have practiced common sense while on the throne, using their power wisely and not abusing it.

All leaders of the Mushroom Kingdom serve for life and can not be impeached, or, specifically, there isn't a known way to abdicate a ruler.

A major issue in the Mushroom Kingdom is kidnapping. When the head of state is kidnapped, a Regent is called to the throne and reigns over the nation as if he or she were the monarch, excercising the exact same powers and authority as the missing ruler. When Peach was a minor, Toadsworth ruled as the Regent of the kingdom, though the title was, for a while, handed over to the Mushroom Chancellor, who is conincidentally Toadsworth's younger brother. The Chancellor managed to serve a quick regency while Mario tried to save his entire dimension, though he was eventually deposed. Toadsworth then took the position back from his brother and continues it to this day. Each time Princess Peach gets kidnapped, Toadsworth assumes the throne as the Regent, promptly awaiting her return.

The Regent's rule tends to be extremely short, since Mario and Luigi save the day within a half of a year at most.

Toadsworth issued many annoying decrees over his years as Regent, namely ones entertaining his persnickity ways of life, such as higher fines for littering and a public ban of spitting on the sidewalk. Peach tends to repeal these upon reassumption of her rightful title.

Recently, the role of the Regent has gone to Peach's daughter, Maria. In her usually short regency, she does some odd things, such as painting the roads red or punishing prisoners by making them do the ALS Ice Bucket Challenge in a thin pair of underpants. If it's long, she does even crazier things, like building so many bridges that her family is charged a huge fee by the time Peach gets back.

The Mushroom Kingdom also has a council of sorts, though it is mostly ceremonial and is actually regarded as annoying by the public. Called the Mushroom Retainers, this council consists of seven Toads who serve for life and for afterlife (should they decide to return as ghost toads or Boos).

Their only outlined powers are to formally redirect the military and national defenses (AKA Mario and Luigi) to the true head of state. This is accomplished by uttering the infamous lines "Thank you {phrase describing defense force), but our Princess (or king, or queen) is in another castle!". While considered annoying by many, they are often not informed as to the actual whereabouts of the head of state during these kidnapping crises. They've shown that when they are in posession of that knowledge, they are more than willing to share it with the rescuing defense force.

The Mushroom Retainers stand in one of the many royal castles of the Mushroom Kingdom, though they are never in the official capitol itself, and for good reason.

While Peach is the ruler, many decisions are made by Maria now. As explained by Laura, the next heir must have as much experience as possible if he or she is to handle the nation one day. Toadsworth also looks after Maria more than Peach, and this is because the closer the heir gets to ruling the kingdom, the more power over the kingdom they have, and the more likely they are to get kidnapped.

Capital
Officially, the capital of the Mushroom Kingdom is Toad Town. However, there are two Toad Towns in the Kingdom, so they are designated Toad Town One and Toad Town Two, with TT1 being the true capitol (with Peach's Castle behind it).

Capitol
By law, every castle owned by the federal/royal government is a Capitol of the Mushroom Kingdom. In other words, if the Princess uses it, it is a capitol. To add to the confusion, most castles go by the identical name of Peach's Castle. There is a Peach's Castle in Toad Town One, a Peach's Castle in Mushroom Kingdom Village (where the Retainers live), a Peach's Castle when the Shroob State reigned (Princess Shroob's Castle), and a Peach's Castle in the outskirts of the kingdom, commonly known as World Eight-Four.

Inhabitants
The Mushroom Kingdom is home to multiple varients of creatures, from Goombas to Toads to Twilighters to Boos to Lakitus, and so on and so on and so on.

Military
Until very recently, the Mushroom Kingdom has had little to no standing army. Until the mid-late 20th century, the Kingdom relied on militias and enlisted guards for it's defence, making it an easy target for warlords and tyrants. After the first defeat of Bowser, the goverment authorized the creation of the Mushrooom Kingdom Defense Force to protect the kingdom. The MKDF, while failing to prevent Bowser from kidnapping Princess Peach on varrious ocasions, has managed to stop most major invasions and takeovers of the kingdom.

Recently, Maria has upgraded the MKDF, giving them rocket launchers, bom-ombs, machine guns, assault rifles, and even paint rollers.
