Moravian Wallachia (, or simply Valašsko; ) is a mountainous ethnoregion located in the easternmost part of Moravia in the Czech Republic, near the Slovak border, roughly centered on the cities Vsetín, Valašské Meziříčí and Rožnov pod Radhoštěm. The name Wallachia used to be applied to all the highlands of Moravia and the neighboring Silesia, although in the 19th century a smaller area came to be defined as ethno-cultural Moravian Wallachia. The traditional dialect represents a mixture of elements from the Czech and Slovak languages, and has a distinct lexicon of Romanian origin relating to the pastoral economy of the highlands. The name originated from the term "Vlach", the exonym of Romanians, who migrated to the northern Carpathians in the Middle Ages and Early Modern times. Geography and anthropology Moravian Wallachia is a mountainous region located in the easternmost part of Moravia in the Czech Republic, near the Slovak border, roughly centered on the cities Vsetín, Valašské Meziříčí and Rožnov pod Radhoštěm. It is part of the Western Carpathians. It is bordered to the west with Lachia () along the Štramberk–Příbor–Frýdek line (according to Šembera) or according to dialectology (according to František Bartoš). Culture The population is traditionally pastoralist. Although animal husbandry was long associated with agriculture practiced in the lowlands adjacent to the Western Carpathians, the Vlach methods and associated rituals of sheep and goat tending were unique and newly introduced by them, as were the introduction of grazing in the highlands and the emphasis upon the production of milk and cheese (bryndza). The "Vlach" dress are still important elements of the ethnography of the Czech Republic, Slovakia and Poland. The music of the area is thought to have been influenced by the Vlachs (e.g. see Lachian Dances), but it also represents a locally vibrant mixture of Vlach with Slovak, Czech, German, and Polish music cultures from the Tatras and Morava valley. History Origin It is unclear exactly why and when the Vlach migrations into what is today Czech Republic and Slovakia occurred. According to Lozovan, the Vlachs were at first Romance-speaking, Orthodox Christian, transhumant pastoralists originating in Transylvania. Kamusella notes that Vlachs migrated up along the Carpathians to Moravia between the 13th and 18th centuries and that most preserved Orthodox Christianity but were Slavicized. Early modern period The Vlachs in eastern Moravia rose up during the Thirty Years' War (1618–48). They fought successfully against Habsburg rule in 1620–23,
