Sēlija– One of Latvia’s Historical Lands
Sēlija is one of Latvia’s historical lands, located on the left bank of the Daugava River. It stretches from Kaplava Parish in Krāslava Municipality in the east to Jaunjelgava and Ērberģe in the west. To the north, it is separated from Vidzeme and Latgale by the Daugava River, while to the west it is divided from Zemgale by the extensive Taurkalne forest massif.
Sēlija can be described in several ways. First, it is the historical territory of the ancient Selonian tribe, approximately two-thirds of whose original area lies within present-day Lithuania. Second, it is an ethnographic and cultural-historical region distinguished by its unique Selonian identity, traditions, and way of life. Third, it is an administrative and territorial entity that was officially granted the status of a historical land of Latvia on 1 July 2021.
From the 16th to the 18th century, Sēlija formed part of the Duchy of Courland and Semigallia. Later, it became part of the Courland Governorate of the Russian Empire. As a result, Sēlija was not subsequently recognised as a separate historical region but was administratively associated with Zemgale. Only in recent years has its distinct historical and cultural identity been officially reaffirmed.

The character and identity of Sēlija are shaped by its green, rolling landscape and by the coexistence of two major Christian denominations—Lutheranism and Roman Catholicism—alongside significant communities of Old Believers and Orthodox Christians. Sēlija is therefore a distinctly multicultural and multi-denominational region. In several Catholic churches in eastern Sēlija, religious services are still conducted in Polish.
The region is also known for its extensive forests, small number of towns, and relatively undeveloped infrastructure. Many roads in Sēlija remain unpaved gravel roads, a fact visitors should take into account when exploring the area. Sēlija is also the least densely populated of Latvia’s historical lands.
One of the most recognisable symbols of Sēlija is its flag. It consists of three horizontal stripes in carmine red, white, and moss green, arranged in the proportion 2:1:2. The flag was officially adopted and consecrated in 1999 during the First Congress of Sēlija. Following the adoption of the Latvian Historical Lands Law, work has also begun on the creation of an official coat of arms for Sēlija.
Sēlija is home to five towns—Aknīste, Ilūkste, Jaunjelgava, Subate, and Viesīte—as well as the parts of Aizkraukle, Daugavpils, Jēkabpils, and Krāslava located on the left bank of the Daugava River. The region also comprises 42 rural parishes.
Viesīte is widely regarded as the centre of Sēlija. This status is linked to its historical importance as the main hub of the narrow-gauge railway network that once connected much of the region, with its principal depot located in Viesīte. The town is also home to the Viesīte Cultural center “Selonia”, one of the largest and most impressive cultural buildings in rural Latvia.
