Selonia in the context of "Krāslava"

Daugavpils (see also other names) is a state city in southeastern Latvia, located on the banks of the Daugava River, from which the city derives its name. The parts of the city to the north of the river belong to the historical Latvian region of Latgale, and those to the south lie in Selonia. It is the second-largest city in the country after the capital Riga, which is located some 230 kilometres (143 miles) northwest and is the ninth most populous city in the Baltic states.

Daugavpils is located relatively close to Belarus and Lithuania (distances of 33 km (21 mi) and 25 km (16 mi), respectively), and some 120 km (75 mi) from the Latvian border with Russia. Daugavpils is a major railway junction and industrial centre, and was an historically important garrison city lying approximately midway between Riga and Minsk, and between Warsaw and Saint Petersburg.

Historical Latvian Lands (Latvian: Latviešu vēsturiskās zemes) or formerly Cultural regions of Latvia (Latvian: Latvijas kultūrvēsturiskie novadi) are several areas within Latvia formally recognised as distinct from the rest of the country. These are: Kurzeme (Courland), Zemgale (Semigallia), Latgale (Latgalia), Vidzeme, and Sēlija (Selonia). While some of these regions are seen purely as culturally distinct, others have historically been parts of different countries and have been used to divide the country for administrative and other purposes.

On 16 June 2021, the Saeima adopted the Historical Latvian Lands Law [lv] which aims to create the necessary preconditions for strengthening the common identity of the population and for the preservation and sustainable development of the cultural and historical environment and cultural spaces of the historical Latvian lands. The Law assigns each parish and town in Latvia to one of the five historical Latvian regions: Vidzeme, Latgale, Kurzeme, Zemgale, and Sēlija. The state city of Riga, a Baltic metropolis, is a historical part of Vidzeme and the special identity and the particularities of the cultural and historical environment of Riga should be supported and promoted.

Selonian was an East Baltic language, which was spoken by the East Baltic tribe of the Selonians, who until the 15th century lived in Selonia, a territory in southeastern Latvia and northeastern Lithuania. The language persisted until the 16th century.

The Selonians (Latvian: sēļi; Lithuanian: sėliai, from Livonian: sälli – "highlanders") were a tribe of Baltic peoples. They lived until the 15th century in Selonia, located in southeastern Latvia and northeastern Lithuania. They eventually merged with neighbouring tribes, contributing to the ethnogenesis of modern Latvians and Lithuanians. They spoke the Eastern Baltic Selonian language.
