Latgalian language
Originally Latgalians were a tribe living in modern Vidzeme and Latgale. It is thought that they spoke the Latvian language, which later spread through the rest of modern Latvia, absorbing features of the Old Curonian, Semigallian, Selonian and Livonian languages. The Latgale area became politically separated during the Polish–Swedish wars, remaining part of the Polish–Lithuanian Commonwealth as the Inflanty Voivodeship, while the rest of Latvians lived in lands dominated by Baltic German nobility. Both centuries of separate development and the influence of different prestige languages likely contributed to the development of modern Latgalian as distinct from the language spoken in Vidzeme and other parts of Latvia.
History of the Jews in Latvia
According to the population census taken in the Soviet Union in 1959, there were 36,592 Jews (17,096 men and 19,496 women; 1.75 percent of the total population) in the Latvian SSR. It may be assumed that about 10,000 of them were natives, including Jewish refugees who returned to their former residences from the interior of Russia, while the remainder came from other parts of the Soviet Union. About 48 percent of the Jews declared Yiddish as their mother tongue. The others mainly declared Russian as their language, while only a few hundred described themselves as Latvian-speaking. Of the total, 30,267 Jews (5/6) lived in Riga. The others lived in Daugavpils and other towns. According to private estimates, the Jews of Latvia in 1970 numbered about 50,000. The overwhelming majority of them lived in Riga, the capital, which became one of the leading centers of national agitation among the Jews of the Soviet Union. Underground religious and Zionist activity resulted in greater suspicion by authorities.
