Latvia
The share of ethnic Latvians had fallen from 77% (1,467,035) in 1935 to 52% (1,387,757) in 1989. In 2011, there were even fewer Latvians than in 1989, though their share of the population was larger – 1,285,136 (62.1% of the population).
The sole official language of Latvia is Latvian, which belongs to the Baltic language sub-group of the Balto-Slavic branch of the Indo-European language family. Another notable language of Latvia is the nearly extinct Livonian language of the Finnic branch of the Uralic language family, which enjoys protection by law; Latgalian – referred to as either a dialect or a distinct separate language of Latvian – is also formally protected by Latvian law but only as a historical variation of the Latvian language. Russian, which was widely spoken during the Soviet period, is still the most widely used minority language by far (in 2011, 34% spoke it at home, including people who were not ethnically Russian).
While it is now required that all school students learn Latvian, most schools also include English, Russian and German in their curricula. English and Russian are also widely accepted in Latvia, especially in business and tourism. there were 109 schools for minorities that use Russian as the language of instruction for 40% of subjects (the remaining 60% of subjects are taught in Latvian).
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).
