Koopa Kingdom

Koopa Kingdom is the Bowser's domain as well as the home of the Koopalings, homeland of the Koopa species, rival kingdom of Mushroom Kingdom, and is the last world in Mario's adventures.

The geography is extremely volcanic, some areas being wastelands, volcanoes, lava rivers and largely untouched by sunlight. This country was defended by the military forces of Koopa Troop with large numbers of tanks and airships patrol these lands to be defeated by Mario and Luigi. Shown in the Yoshi series, Bowser is ruler of the Koopa Kingdom since childhood and is located to Dinosaur Land.

Government
In contrast to others Mushroom World kingdoms, the Koopa Kingdom is a dictatorship. Bowser acts as the head of the government when he was child, while his title as "King" raises arguments of what his presence in the government is. Kamek remains as adviser for many years, gives advice to the Bowser and his children. [http://mario.wikia.com/wiki/Bowser_Jr. Bowser Jr.] takes over as the heir to the throne.
