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. The distinct cultural heritage is also mirrored by the Y-chromosome genetic results, with Moravian Vlachs resembling isolated Balkan groups such as Aromanians more than the surrounding Central European populations.
Early modern period , 1787 The Vlachs in eastern Moravia
rose up during the
Thirty Years' War (1618–48). They fought successfully against Habsburg rule in 1620–23, and were initially supported by rebellious Protestant Hungarians. Having had all of Moravia east of the Morava river under their control by 1621, the Vlachs were defeated in 1623, after which a series of public executions took place. They renewed attacks in late 1623, and notably defeated a Polish contingent in March 1624. In 1625–30 Habsburg and Danish armies repeatedly crossed Moravia. The Vlachs joined the Danes, and later, the Swedes. After the Danish retreat in 1627, and Swedish retreat in 1643, the Habsburgs finally defeated the Vlachs in 1644.
Modern period Since at least the mid-18th century the population of Moravian Wallachia described itself as Wallachian. At that time, in German, the community was known as
die Wallachey. replaced the term Ualachy (Vlahi) with Ualassko (Valasko), and defined the Moravian Wallach as a shepherd, and stressed that the term had nothing to do with Romanians. He noted that the speech was of elements of Polish and East Slavic dialects. In 1866,
Hyde Clarke reported that the Moravians viewed the Moravian Vlachs (
Wallachians) as an "alien race", but Slavic-speaking. They had characteristic habits and dress. ==Notable people==
