Vladimir Yaroslavich
In 1042, Vladimir made a victorious campaign on the tribes Yam’ (territory of Southern Finland), and the next 1043 he went to Byzantium together with III the Cruel. The Byzantine campaign ended in failure, but there is a version that in 1044, Vladimir took Chersonese.
It was canonized by the Russian Orthodox Church in the 15th century, as “the holy noble prince Vladimir Yaroslavich of Novgorod”.
Izyaslav (Dmitry) Yaroslavich
Together with his brothers Svyatoslav and Vsevolod, they created the Triumvirate of Yaroslavichy – the princes ruled the southern lands of Kievan Rus in 1054-1073 without entering into a confrontation. Enmity broke out between the brothers in 1073, and in 1078 Izyaslav died during a battle with the troops of his nephews.
Svyatoslav (Nikolay) Yaroslavich
On November 1, 1068, near Snovsk, Svyatoslav defeated the Polovtsians after being defeated by them on the Alta River with his brothers.
In 1073, having entered into a conspiracy with Vsevolod, overthrew Izyaslav, who fled to Europe. December 27, 1076 Svyatoslav died in the 50th year of life, becoming the first known victim of an unsuccessful surgical operation in Russia: he died from “cutting the tumor”.
Vsevolod (Andrey) Yaroslavich
In 1046 he married a relative (presumably a daughter) of the Byzantine emperor Constantine IX Monomakh, from the marriage with which Vladimir Monomakh was born – the future grand duke.
He reigned in Kyiv in 1076-1077 and from 1078 until the end of his life, he was the first ruler of Kyiv, who used the title “Prince of All Russia.”

History of Russia from the founding of the monarchy by Rurik to the reign of Catherine
(1036—1060)
Like his brother Vyacheslav, Igor died at an early age – in 1060. At the time of his death, he was about 24 years old. He left his young sons: Davyd and Vsevolod, who became rogue princes and, by the decision of the senior Yaroslavichs, did not inherit lands from their father.
Testament of Yaroslav the Wise to his sons
Yaroslav the Wise, before his death, divided a land between his children, and from that time on, an appanage system began to develop in Old Rus. Yaroslav gave his sons a testament of how they should treat each other, and this testament served as the basis for the mutual relations of the princes in the specific period.
«Here I am moving away from this world, my children! love one another, because you are brothers, from the same father and from the same mother. If you live in love with one another, then God will be with you. He will subdue all your enemies and you will live in peace. If you begin to hate each other, quarrel, then you will perish and destroy the land of your fathers and grandfathers, which they acquired with their great labor. So live peacefully, obeying one another; I entrust my throne of Kyiv instead of myself to my eldest son and your brother Izyaslav: obey him, asobeyed me, let him be instead of me».
