Vladimir II Monomakh (Russian: Владимир Мономах; Ukrainian: Володимир Мономах; Christian name Vasiliy, or Basileios) (1053 – May 19, 1125) was a Velikiy Kniaz (Grand Prince) of Kievan Rus'.

He was the son of Vsevolod I (married in 1046) and Anastasia of Byzantium (d. 1067), whose father some give as Emperor Constantine IX Monomachos, but this is not attested in any reliable primary source.

Eupraxia of Kiev, a half-sister of Vladimir, became notorious all over Europe for her divorce from the Holy Roman Emperor Henry IV on the grounds that he had attempted a black mass on her naked body.

In his famous Instruction (also known as The Testament) to his own children, Monomakh mentions that he conducted 83 military campaigns and 19 times made peace with the Polovtsi. At first he waged war against the steppe jointly with his cousin Oleg, but after Vladimir was sent by his father to rule Chernigov and Oleg made peace with the Polovtsi to retake that city from him, they parted company. Since that time, Vladimir and Oleg were bitter enemies who would often engage in internecine wars. The enmity continued among their children and more distant posterity.

Vladimir (Russian: Влади́мир; IPA: [vlɐˈdʲimʲɪr]) is a city and the administrative center of Vladimir Oblast, Russia, located on the Klyazma River, 200 kilometers (120 mi) to the east of Moscow along the M7 motorway. Population: 345,598 (2010 Census preliminary results); 315,954 (2002 Census); 349,702 (1989 Census).

Vladimir was one of the medieval capitals of Russia, and two of its cathedrals are a World Heritage Site. It is served by the Semyazino Airport, and during the Cold War Vladimir was host to Dobrynskoye air base.

The area occupied by the city of Vladimir has been inhabited by humans (at least intermittently) for approximately 25,000 years (see Sungir). Traditionally, the founding date of Vladimir has been acknowledged as 1108, as the first mention of Vladimir in the Primary Chronicle appears under that year. This view attributes the founding of the city, and its name, to Vladimir Monomakh, who inherited the region as part of the Rostov-Suzdal Principality in 1093. In 1958, the 850th anniversary of the city foundation was celebrated, with many monuments from the celebrations adorning the city squares.
