Kievan Rus'

Kievan Rus' (also known as Kyivan Rus) was a medieval state in Europe.  
Overview
The Kievan Rus lasted from the late 9th to the mid 13th century. It broke apart under the Mongol invasion of 1237–1240. At its peak, it stretched from the Baltic Sea in the north to the Black Sea in the south, and from the upper Vistula in the west to the middle Volga in the east.
Name
The state was called "land of Rus'" in broader sense. In the core sense, this term described the territory of Dnieper Ukraine, which served as the heartland of the state.Motsia, Oleksandr (2009). «Руська» термінологія в Київському та Галицько-Волинському літописних зводах ["Ruthenian" question in Kyiv and Halych-Volyn annalistic codes] (PDF).

History
The early part of the state is sometimes known as the "Rus Khaganate".  The history of Rus' proper begins in 882.  This is when prince Oleg seized Kyiv and became the first prince of Kyiv. This was after Varangians (Vikings), who were presumably led by Askold and Dir, became Kyiv's first Norse rulers and freed this slavic city from the Khazars' tribute.
Peak
The state reached its peak of power in the mid 11th century. Its lands went south to the Black Sea, east to the Volga, and west to the Kingdom of Poland and to the Duchy of Lithuania.; see also   and
