Early Middle AgesThe Early Middle Ages (or early medieval period), sometimes controversially referred to as the Dark Ages, is typically regarded by historians as lasting from the late 5th or early 6th century through the 10th century. They marked the start of the Middle Ages of European history, following the decline of the Western Roman Empire, and preceding the High Middle Ages ( 11th to 14th centuries). The alternative term late antiquity, for the early part of the period, emphasizes elements of continuity with the Roman Empire, while Early Middle Ages is used to emphasize developments characteristic of the earlier medieval period.
Polans (eastern)The Polans or Polians (Поляни, Poliany; Поляне, Polyane; Polanie; Old East Slavic: Полѧне, Polęne), also known as Polanians, Polianians, and Eastern Polans, were an East Slavic tribe between the 6th and the 9th century, which inhabited both sides of the Dnieper river from Liubech to Rodnia and also down the lower streams of the rivers Ros', Sula, Stuhna, Teteriv, Irpin', Desna and Pripyat. The distinct western Polans of the Early Middle Ages were a West Slavic tribe, ancestors of the Poles.
KhazarsThe Khazars (ˈxɑːzɑːrz) were a nomadic Turkic people that in the late 6th-century CE established a major commercial empire covering the southeastern section of modern European Russia, southern Ukraine, Crimea, and Kazakhstan. They created what for its duration was the most powerful polity to emerge from the break-up of the Western Turkic Khaganate. Astride a major artery of commerce between Eastern Europe and Southwestern Asia, Khazaria became one of the foremost trading empires of the early medieval world, commanding the western marches of the Silk Road and playing a key commercial role as a crossroad between China, the Middle East and Kievan Rus'.
