The second half of the 11th century witnessed the acute fight for power among Yaroslav the Wise's grandchildren in Kiev and separate princedoms. Lasting and blood-shedding clashes among numerous sons and grandsons of the Knyaz weakened Russia. The threat of cuman invasion became real. It was necessary to take urgent measures. At that time Vladimir Monomakh, the grandson of Yaroslav the Wise, well known for his victorious raids on cuman, entered the Russian political scene. During his reign (1113 – 1125) the situation in Russia was stable. For a time being Vladimir Monomakh managed to govern the entire Russian land and strengthen Russia’s international reputation. His name is associated with the famous crown of Russian tsars – Monomakh’s Cap.
