Munchkinland (later known as the Free State of Munchkinland) is the eastern quadrant of Oz.
People hailing from Munchkinland are called Munchkinlanders, but are sometimes pejoratively referred to as Munchkins because of their small stature.
Munchkinland is the birthplace of Elphaba and Nessarose, the Wicked Witches of the West and East respectively. Elphaba had the birthright of being the Eminence of Munchkinland, but after Elphaba fled from the public, her father named Nessarose the successor.
Nessarose became the leader of Munchkinland and broke away from loyal Oz. She declared Munchkinland's independence and established the Free State of Munchkinland. She began instating new laws to prohibit Animals and informed her people to destroy the yellow brick road and other passages into Munchkinland. She soon became known as the Wicked Witch of the East.
The Munchkinlanders rejoiced after Nessarose's death, caused by Dorothy's house crushing her, but they soon moved on to attack the troops of the Emerald City and Loyal Oz.
In Wicked it was stated that Munchkinland is ruled by about a dozen family Eminences, though the Thropp Family is by far the most prominent. The Eminent Thropps claim the legitimacy of rule over all of Munchkinland. Their seat of power is at Colwen Grounds located in Nest Hardings of Munchkinland. His Eminence Peerless Thropp ruled Munchkinland for years, surviving both his children and grandchildren, until his great-granddaughter Nessarose Thropp succeeded him as Eminent Thropp.
In Out of Oz, the latest Eminence of Munchkinland was a witch called La Mombey. She moved the seat of power to Bright Lettins.
