On October 19, 1097, the first congress of Russian princes was held in Lyubech to avert perpetual warfare among the leaders. Under the direction of Great Prince Vladimir Monomakh, it was legally agreed to divide the country into appendage principalities.
The year 1097 was significant in Russia's history. The events of the previous year, when Cuman Khan Bonyak ravaged the vicinity of Kiev, convinced the constantly rivaling princes of Kievan Rus of the need to cooperate.
Vladimir Monomakh, who lost a son in a fight against the Cumans, called the congress of princess at the city of Lyubech, located at the junction of Kievan, Chernigovsk and Smolensky lands.
On October 19, via the drawbridge into Lyubech, entered Vladimir Monomakh, Svyatopolk II, David Igorevich, their cousin Vasilko Rostislavovich and Oleg and David Svyatoslavovich. All five men were grandsons of Yaroslav The Wise and in their hands lay the future integrity and prosperity of Rus.
They agreed that they would care for the Rus land “as one heart” and that each would hold their own paternal land and let their families inherit them. This broke the Rota System (collateral succession) that was observed for two centuries and effectively established a feudal system in Kievan Rus.
Unfortunately, the good intentions of the princes did not always correspond with their actions and the peace that had been established did not last long. Shortly after visiting Lyubech, David Igorevich, incited by Svyatopolk II, captured and blinded Prince Vasilko Rostislavovich, which led to wars between the princes.
