Schwarzberg, officialy Province of Schwarzberg (Portuguese: Província de Schwarzberg), formerly the Principality of Negromonte, is one of the six provinces and seven administrative divisions of the Kingdom of Ebenthal. It is the only province of Ebenthal enclaved in two different Brazilian cities (and states), in Itatiaia and Juiz de Fora, spanning circa of 0.6km² with 11 permanent inhabitants. The province is governed as a devolved government through an appointed President, who is currently the former reigning Prince of Negromonte, Hugo (IV) Toledo. Schwarzberg is further subdivided into two municipalites: the capital city of Maldras, Frumar and Andeca, all named after Suebi monarchs. Schwarzberg is represented at the House of Councillors by two elected Councillors. Schwarzberg also happens to be the only province in the country which has recorded snowfall and the lesser temperatures so far.
Schwarzberg's history pre-dates its micronational existence, having serving as route to inland Amerindians to reach the Atlantic coast. Following the Portuguese colonization and the creation of the State of Brazil, the Eastern Region of modern-day Schwarzberg, the Juiz de Fora enclave, served as a trading post on the Luso-Brazilian gold route, while the Wesrtern Region, the Itatiaia enclave, was deserted. Over the course of the 19th century, as Brazil became independent, both Juiz de Fora and Itatiaia, then part of the municipality of Resende, were permanently settled and converted into towns. In 1888 the Toledo dos Santos family settled in Juiz de Fora, and later in the second half ot the 20th century, as Itatiaia finally became a municipality of its own, part of the Toledo family moved there for work. In early 2015, the government of the seccessionist and unrecognized Kingdom of Ebenthal approached the Toledo dos Santos family, inviting some of its members, known to the Ebenthali government, to become politicians in the new country. With the acceptance, Hugo de Toledo, the main heir to his family's possessions, signed the sovereignty concession contract by which the properties and areas to which he is entitled were incorporated into Ebenthal under the name of Negromonte, in allusion to Pico das Agulhas Negras, and he was proclaimed Prince of Negromonte. Four monarchs succeeded each other on the throne of Negromonte until 5 February 2022 when the Negromontine monarchy was abolished through the Ebenthali Unitary Act and the principality became a province, subsequently renamed by the Luso-Germanic Cultural Commission as Schwarzberg.
The principality's name, "New Switzerland", comes from the geographical region in which it is located, and from its historical colonization by immigrants mainly of Swiss origin, but also by Austrians and Germans. In the process of colonization and settlement, the Brazilian city of Nova Friburgo, in which the principality is enclaved, became the main nucleus of Swiss immigration, having received the nickname of Swiss Brazilian, and sometimes, New Switzerland.
