During the Late Iron Age, the southeastern part of Latvia, particularly the upper and middle course of the River Dubna, was one of the most densely populated areas of Latgallian habitation. In the course of archaeological research at Late Iron Age cemetery sites, various burial practices have been observed that have not been encountered at Latgallian burial sites outside this area. Here, in addition to evidence of the familiar Latgallian burial practices, horse-trappings have been found in several tenth to 11th-century male grave inventories.
