The story from the Russian Primary Chronicle is that the Slavs of Kiev were fighting among themselves. To restore order they invited the legendary Varangian Rus Rurik to be their leader. This is another area of controversy. One school of thought accepts the Russian Primary Chronicle account with the Norman origin of the Rus' people. The opposing view says the Scandinavians played a small part in the creation of the Kievan Rus. The Scandinavians were simply hired by the Slavs to protect them. Since the 1990s there has been a further controversy over who, Russia or Ukraine, had a better claim to be descended from the Kievan Rus princes. Since the breakup of the USSR Russian historians are not forced to accept the anti-Norman theory.
