Latgalian language
Latgalian is spoken in Latgale, the eastern part of Latvia. It is debated whether it is a separate language or a distinct dialect of Latvian. Nevertheless, its standardized form is recognized and protected as a "historical variety of the Latvian language" "(vēsturisks latviešu valodas paveids)" by Latvian law. The 2011 Latvian census established that 8.8% of Latvia's inhabitants, or 164,500 people, speak Latgalian daily. 97,600 of them live in Latgale, 29,400 in Riga and 14,400 in the Riga region.
Latgalians (modern)
During the first independence of Latvia (1918–1940), Latgale was the only region of Latvia with strong regional political parties. Although Latvian governments mainly promoted a united Latvian culture, fostering assimilation of Latgalians, especially after the coup by Kārlis Ulmanis in 1934, the Latgalian language was also used. Books were published in Latgalian, it was taught in some schools, and people could choose to use Latgalian when communicating with the government. They were classified as a Narodnosti in the First All Union Census of the Soviet Union in 1926. In the Nazi German "Generalplan Ost", as far as can be told from the surviving documentation, the Latgalians were scheduled for deportation, while only half of the Latvian population was to be treated so. The reasons for this difference are unclear, but possibly based on racist linguistic arguments, considering that the Nazis planned to physically remove 85% of the Lithuanians (whose language – and by erroneous inference ethnicity – has similarities to Latgalian).
