Latvian language
Upper Latvian dialect is spoken in Eastern Latvia. It is set apart from rest of the Latvian by number of phonetic differences. The dialect has two main varieties – Selonian and Non-Selonian. There is a standard language, the Latgalian language, which is based on deep Non-Selonian varieties spoken in south of Latgale. The term "Latgalian" is sometimes also applied to all Non-Selonian varieties or even the whole dialect. However, it is unclear if it is accurate to use the term for any varieties besides the standard language. While the term may refer to varieties spoken in Latgale or by Latgalians, not all speakers identify as speaking Latgalian, for example, speakers of deep Non-Selonian varieties in Vidzeme explicitly deny speaking Latgalian.
History of Riga
Between World War I and World War II (1918–1940), Riga and Latvia shifted their focus from Russia to the countries of Western Europe. A democratic, parliamentary system of government with a President was instituted. Latvian was recognized as the official language of Latvia. Latvia was admitted to the League of Nations. The United Kingdom and Germany replaced Russia as Latvia's major trade partners. As a sign of the times, Latvia's first Prime Minister, Kārlis Ulmanis, had studied agriculture and worked as a lecturer at the University of Nebraska in the United States of America.
