For people who do not know :
((©)) - According to the Primary Chronicle of Rus, the Rus (a group of Varangians), had relocated from the Baltic region to North-eastern Europe (Holmgård - Novgorod, which is in Russia)creating a state which finally came under the leadership of Rurik . LATER Rurik's relative Oleg came to Kiev and founded Kievan Rus.
The descendants of Rurik were the ruling dynasty of Rus (Russia+Ukraine+Belarus) for centuries(more than 7 centuries). Many people don't know (because "historians" don't want them to know )

After the mongol invasion Rurik dynasty (Yaroslav II of Vladimir, Alexander Nevsky) MOVED FROM KIEV TO THE CITY OF VLADIMIR, WHICH IS NOW IN RUSSIA.

Later Kiev was captured by Grand Duchy of Lithuania, and then it belonged to Polish–Lithuanian Commonwealth.
The whole history the territory of modern Ukraine was divided:
one (the biggest one) part belonged to Kiev Rus'/ Russian Empire/USSR
the second one - to Poland (Galicia)
the third one - to Romania (Bukovina)...

So we still love each other , there is no fuss and hatred between Russians and Ukrainians ( and also Belarussians) , we still know we were brothers and sisters , unless those who got brainwashed ( it is more popular in Western-Ukraine )
