Latvian language
The history of the Latvian language (cf. below) has placed it in a peculiar position for a language of its size whereby it is spoken by a large number of non-native speakers as compared to native speakers. The immigrant and minority population in Latvia is 700,000 people: Russians, Belarusians, Ukrainians, Poles, and others. The majority of immigrants came to Latvia between 1940–1991; supplementing pre-existing ethnic minority communities (Latvian Germans, Latvian Jews). In a recent survey, 60% of Latvia's ethnic minorities described their knowledge of Latvian as fluent. Fluency in Latvian is prevalent among the younger generations of the minorities.
Latvia
Several important cultural changes occurred during this time. Under Swedish and largely German rule, western Latvia adopted Lutheranism as its main religion. The ancient tribes of the Couronians, Semigallians, Selonians, Livs, and northern Latgallians assimilated to form the Latvian people, speaking one Latvian language. Throughout all the centuries, however, an actual Latvian state had not been established, so the borders and definitions of who exactly fell within that group are largely subjective. Meanwhile, largely isolated from the rest of Latvia, southern Latgallians adopted Catholicism under Polish/Jesuit influence. The native dialect remained distinct, although it acquired many Polish and Russian loanwords.
