What is the name of the Baltic tribe duke known as King Vester?
Viestards Viestards (also "Viesthard, Vesthardus, Viesturs") was one of the greatest Semigallian dukes in the 13th century, referred to as King Vester (Old High German: "konic Vesters" ). His capital was Tērvete hillfort. During the first decades of the 13th century he was allied with the Livonian Brothers of the Sword against Lithuanians, who looted Semigallia on several occasions. In 1205, joint forces of semigallians and crusaders defeated Lithuanians and killed duke Žvelgaitis.
Vistula Veneti The term Vistula Veneti (or Baltic Veneti) has been used in modern times to distinguish the Veneti noted by Greek and Roman geographers along the Vistula and the Bay of Gdańsk from other tribes around them and other tribes of the same name elsewhere such as the Adriatic Veneti (about the same area of today's Veneto), the Veneti of Brittany, and the so-called Paphlagonian Veneti (of today's northern Turkey coast). They are one of the tribes that are suspected as the ancestors of some or all of today's Slavs.
