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.
Latvian language
Until the 19th century, the Latvian language was heavily influenced by the German language, because the upper class of local society was formed by Baltic Germans. In the middle of the 19th century the First Latvian National Awakening was started, led by “Young Latvians” who popularized the use of Latvian language. Participants in this movement laid the foundations for standard Latvian and also popularized the Latvianization of loan words. However, in the 1880s, when Czar Alexander III came into power, Russification started. During this period, some Latvian scholars suggested adopting Cyrillic for use in Latvian. After the czar's death, around the start of the 20th century, nationalist movements reemerged.
