The Semigallians in the context of the other Baltic tribes,
circa 1200
CE. The Eastern Balts are shown in brown hues while the Western Balts are shown in green. The boundaries are approximate.
The 'Semigallians' (
Latvian ''Zemgaļi'', also Zemgalians, Semigalls, Semigalians) are one of the
Baltic tribes that lived in
Zemgale, in the southcentral
Latvia. They are noted for their long resistance to the German
crusaders, the
Livonian Brothers of the Sword.
One of the theories is that the Semigallians were one of the first Baltic tribes to establish a
monarchy, albeit weak in comparison to the power of the Semigallian nobles, although this has not been confirmed yet.
Notable leaders
One of the most notable Semigallian leaders was
Viestards (Viesturs). Upon uniting hostile Semigallian clans into a single state in early
13th century, Viestards formed an alliance with the German crusaders to defeat his enemies on the outside. After the crusaders broke the treaty and invaded his lands, he allied with
Lithuanians, resulting the near annihilation of the Livonian Brothers of the Sword in the
Battle of Saule in
1236.
Nameitis (Namejs, Nameisis), another renowned Semigallian leader, united Semigallian and Lithuanian tribes for a retaliatory counterattack on German lands (Prussia). Main sources for his activities are ''Livländische Reimchronik'' and ''Das Zeugenverhör des Franciscus de Moliano (1312).'' What is known with certainty, however, is that by the end of 1270s, a new powerful leader had emerged who achieved several major victories over German crusaders in Zemgale and East Prussia.
Semigallians continued their resistance until
1290, when they burned their last castle in
Sidrabene and a large number of Semigallians migrated to Lithuania and once there continued to fight against the
Germans.
