|History of Latvia|
Latgalians, sometimes also Ancient Latvians (Latin: Lethi, Letthigalli, Low German: Letti, Lethi, modern Latvian: latgaļi, letgaļi, leti, variant translations also include Latgallians, Lettigalls or Lettigallians) were an ancient Baltic tribe. They likely spoke the Latvian language, which probably became the lingua franca in present-day Latvia during the Northern Crusades due to their alliance with the crusaders. Latgalians later assimilated the neighboring tribes, forming the core of modern Latvians.
The Latgalians were a Eastern Baltic tribe whose origin is little known, who, in the 5th and 6th centuries, dwelt only in the eastern part of present-day Vidzeme (westwards from the Aiviekste River), and later on, in nearly all the territory of that region. In written sources, they are mentioned from the 11th century. In the first two decades of the 13th century, the (Western) Latgalians allied with German (mainly Saxon) crusaders, and their lands (Eldership of Tālava, Principality of Jersika, Principality of Koknese) as vassal states were incorporated into Livonia. Already in 11th century Eastern orthodoxy started to spread in Latgalian lands from Polotsk and Pskov. In 12th century Latgalian lands and their rulers paid tribute to dukes of Polotsk. In 13th century during the Livonian crusade Latgalian elders changed their Eastern orthodoxy for Roman Catholicism and became vassals of Livonian Order.
Due to crusade many regions of Semigallia and Courland were left depopulated so already during the war and also after it part of the latgalians migrated to those regions. Subsequently between 13th and 16th centuries, they gradually assimilated other Baltic tribes Selonians, Semigallians and Curonians who thus became a part of today's ethnic Latvians.
In the lands of the Western and the Eastern Latgalians, about 80 flat cemeteries of Western Latgalian origin have been excavated, with more than 2000 burials uncovered. The first large scale excavations took place in Ludza Odukalns Cemetery in Latgale (1890-1891), where 339 Late Iron Age burials were uncovered. In the excavations at Pildas Nukši Cemetery (in Latgale, 1947-1948), 218 burials were uncovered, dated to 9th-12th century, while at Zvirgzdenes Kivti Cemetery (in Latgale; 1948, 1955-1958) 175 burials from the 7th-12th century were excavated. 315 burials were found at Aglonas Kristapiņi Cemetery (in Latgale; 1928, 1938, 1977-1980, 1984-1987, 1999-2000), in use from the late 8th to 12th century. Ērgļu Jaunāķēni Cemetery was totally excavated in 1971-1972, when 89 burials were found. At Koknese Cemetery 102 burials from the Late Iron Age were uncovered (1986-1989). In the area of Gauja's Latgallians two cemeteries, Drabešu Liepiņas and Priekuļu Ģūģeri are well excavated too.
Archaeological excavations have also been carried out on the hillforts of Ķente, Koknese, Sārumkalns, Tanīskalns, as well as on other Latgalian sites. Only a few (Western) Latgalian settlements have been excavated; large scale excavations (1960s-1970s) and reconstruction has been done at the Āraiši lake dwelling site (9th century).
In Latgale, dating from the 6th-7th centuries, there were flat cemeteries as well as barrow cemeteries, but in the 9th-10th century the transition started from flat graves to barrows. There are about 15 excavated Eastern Latgalian barrow cemeteries, but usually only a small number of barrows were investigated.
Archaeologically identified dwelling-sites in Latgale include hill forts, settlements and lake dwellings. Among hillforts, well researched is Jersika Hillfort (excavated in 1939 and from 1990 onwards), forming complex together with Dignāja Hillfort, on the opposite bank of Daugava. Jersika was occupied in the 10th-14th century, probably after the decline of Dignāja, which had been inhabited since the 6th century.
It is possible that ancestors of the so-called Eastern Latgalians migrated to the territory of present-day Latgale in the 7th and 10th-11th centuries, pushed from their previously inhabited territory by Slavic migration; some archaeologists also believe that the Eastern Latgalians formed from the most ancient East-Baltic inhabitants of Latvia, who lived in central and Eastern parts of Latvia just in the "Roman" Iron age (1st-4th centuries).
