The Mushroom Kingdom (briefly Kingdom of Mario Land in SMG4: Mario The Supreme Leader) is a monarchical governed state, a principality ruled by the Toadstool Dynasty that which is almost always the main setting where SMG4's bloopers take place, located somewhere near Europe and the Mediterranean Sea, possibly in the Atlantic Ocean. There are many different species that reside in the kingdom including Toads (the majority), humans, Goombas, Koopas and Teletubbies. The members of SMG4's Gang gang also live there, with the sole exception of Tari.



The Mushroom Kingdom is a country where most of the Mario games take place. The geography of the country varies, from green plains, jungles, deserts, snowy lands and volcanic areas. In the series, it is shown to be very mountainous, and it is also a fact that it sits in a rift in one of the tectonic plates in the Atlantic Ocean, possibly at the tripoint of the North American, African and Eurasian plates, therefore forming mountains such as Mount Shiver (in SMG4: Little Penguin Lost) and Mount Doom (in SMG4: Mario Scratches His Ass).

From evidence in the series, it is shown that the green plains is where most of the citizens live and where the desert is the most inhospitable places to live, with only a few people living there and due to high radioactivity in the region due to an amount of nuclear test sites being located there.

The capital of the kingdom is called Mushroom City. Meanwhile, the official currency in the kingdom is the Mushroom dollar, which uses Mushroom coins. All vehicles in the kingdom drive on the right side on the road, with the steering wheel on each car on the left side. However, it is shown in some videos that vehicles would drive on the left side of the road (much like its seen in countries such as in Australia, Britain, and Japan), probably due to the series being made in Australia, where cars drive on the left side. Still, steering wheels are located on the left.

The kingdom is shown to be very racially diverse, with the population comprising Toads, humans, Koopas, Teletubbies, Goombas and more. Meanwhile, the human population in the Mushroom Kingdom is mostly comprised of Italian immigrants, who emigrated from Italy in the past, evidence in people like Mario and Luigi. The Mushroom Kingdom is seen as an opposite to its neighbor Inkopolis as it is shown to be anti-discriminatory towards people of other races, unlike Inkopolis, due to having a homogenous population of Inklings.


(see Mushroom Kingdom Government for more)

The Toadstool family is the ruling dynasty over the citizens of the Mushroom Kingdom, with the current ruler being Peach Toadstool, the Princess of the kingdom, taking over the role from her unseen father, the Mushroom King. She resides at her official residence, which is her castle located north of the capital. While the monarch is the head of state of the kingdom, most of the power in the country is handled by the President of the Mushroom Kingdom, who is the head of government and the monarch's adviser, as seen in Super Mario 64 Bloopers: President Toad Washington. This is unusual since the head of government in a monarchial state is usually called the Prime Minister.

As evidenced in most games, the President of the Mushroom Kingdom has been in fact mostly Toads. Here below is the list of people so far who became president:

(1996 - 2000)

(2000 - 2002)


It is unknown who is the president after 2002.


In the early years, the land known as the Mushroom Kingdom was sparsely inhabited, with just few inhabitants living on the land for decades, with some Toads, Koopas and Goombas living there, and spoke their own languages (with Toads speaking their Toad language). It wasn't until human pilgrims from Western Europe came here, and tried to live off the land, but however were threatened, that was until the natives came to their help and they managed to survive in the new land they were now living in, as told in a non-Bob version of the story in SMG4: Mario and the Bob Mansion....

Sometime later, it was told that states were formed on the Mushroom land, with the ancestors of the Koopa Royal Family going to form Koopa Land in the volcanic east, while the Toads installed a human dynasty to lead the remaining states Mushroom Kingdom. After sometime, Koopa Land was integrated with the rest of the kingdom, but remained autonomous in its right. European powers began to take notice of the new Atlantic kingdom, and went off to trade with the new kingdom, particularly the French and the Spanish, who set up some colonial outposts there, including the area of Francisco Fajardo seen in SMG4: Stupid Mario Odyssey, the area known as Rochefort, known today as Rockford, and the area of Aubergine and Belmont.

However, as the colonial powers were getting too greedy over the kingdom's resources, and the hatred they both have during the time, the French and Spanish went off to war with each other, with France claiming victory over them, but this however angered the local residents, as France went on to claim sovereignty over the kingdom, effectively removing the Toadstool Dynasty from power. An independence movement was initiated, and effectively made themselves sign the Mushroom Kingdom Declaration of Independence, which is now in display at the Mushroom City Natural History Museum in The Mario Channel: MARIOBUSTERS.

As a result of their independence, the government was reformed, and to get rid of any colonial influence, they changed their lingua franca from French to English, and renamed Rochefort to its Anglicised name. They then introduced some policies that encouraged immigration to the kingdom, which still carries on today in immigrants like Mario and Meggy. A change in government happened, and power was shifted from the monarch to the president.

Not much is known for the next few years, excluding the annexation of Isle Delfino and Yoshi's Island, and the breakaway of Eagleland, but it wasn't until the Cold War happened, with the United States and the USSR testing their nuclear bombs. Feeling pressured, they made and tested their own bombs. However, this had a negative impact on their environment, with many areas evacuated as a result of the testings, and still carry tests today, seen in SMG4: Wario Tries To Stop Himself From Dying.

Currently, the kingdom suggested to have being oppressing those who criticize the monarchy, due to the lèse-majesté laws in place, showing that the country is somewhat not that democratic and free, shown in SMG4: Mario Is Cancelled.

In SMG4: Mario The Supreme Leader, a castle patron, Mario, took the role as the acting King of the Mushroom Kingdom after accidentally having his pet rock wizard sending away the regent, Toadsworth. Assuming his role, he became the first ever monarch to not come from the Toadstool dynasty, and quickly became an efficient leader despite not having any experience in politics. He became power-hungry, effectively cracking down on dissent, and turning the monarchy into a republic, making himself the Supreme Leader of Mario Land. After a failed revolution, he was forced to be stripped of his role after Peach returned from her holiday, and took back the crown, restoring the Mushroom Kingdom and the monarchy.


Due to the massive immigrant and native population staying together on the land, a need for a bridge of communication was necessary, so it stuck with English as the official language of the kingdom. However, the native species remained to speak their own languages, such as Toad, Goomba and Koopa. Nevertheless, foreign languages are continued to be spoken by citizens, such as Italian, French, Spanish, German, Japanese, Chinese and recently Inkling.


Throughout the series' timeline, the kingdom has been seen in much peril, such as being invaded by bootleg supremacists, two T-Pose pandemics, and pro-anime riots. Additionally, there was a timeline set 500 years in the future where sentient Weegee Dolls conquered the kingdom, which fortunately was undone by Luigi, Fishy Boopkins, Shroomy, and Mario's descendant New Super Duper Mario Plus Ultra.

In SMG4: Mario Runs Out Of Toilet Paper, Satan (disguised as the Papa John food mascot) decides to destroy the world and kill everyone just for the fun of it. To do so, he causes a toilet paper shortage in the kingdom. As its citizens depended on the paper, a panic-mass buying of toilet paper began, but thanks to SMG4's Gang, the plot ended.

Even with those catastrophes, the kingdom is able to rebuild every single time, probably due to its strong economy, hinting that it is a developed country.


Regions and Autonomous Territories


Autonomous Territories



Law Enforcement/National Defense Organizations

  • Note: The armed forces services all regions except for the region of Koopa Land, where Bowser's Castle is located, in which they have their own armed forces, independent from them.



  • The Mushroom Kingdom's population is around 15 million people, since, at the beginning of SMG4: Mario and The Diss Track, the counter of Bob's fans is around that number, while Saiko said "everyone in the Mushroom Kingdom are already fans of him", although she could just be exaggerating.
  • In the Nintendo counterpart, Bowser rules the Koopa Kingdom, but in SMG4's universe, he and all Koopas seem to live along with the residents of the Mushroom Kingdom.
  • The Mushroom Kingdom has been through numerous apocalyptic events and attacks; too many to even count, but notable events include:
  • The Mushroom Kingdom may possibly be located at Europe and the Mediterranean Sea, according to SMG4: A Day In The Life Of Everyone.
  • The Mushroom Kingdom may have been under foreign powers and was ruled by a colony as a certain European country, which explains the appearance of the Declaration of Independence in MarioBusters.
  • The Mushroom Kingdom could be a constitutional monarchy, as Tari has stated the word "President". But it could possibly be a former constitutional monarchy before converting into an absolute monarchy.
  • Tari is the only member of SMG4's Gang to not reside in the kingdom, as she is revealed to be from Onett in SMG4: The Big Bad Bully.
