Most western scholars believe them to be a group of Varangians, specifically from Pomerania. According to the "Povest vremennykh let" or Russian Primary Chronicle of Rus', compiled in about 1113 AD, the Rus' had relocated from Pomerania. Their leader was named Rurik. Later, Rurik's relative Oleg captured Kiev, founding Kievan Rus'. The descendants of Rurik were the ruling dynasty of Rus' (after 862). In the controversy, this is called the "Normanist" view. There are also thoose who believe the Rus came from Sweden or Rothi or Roslagen as it is known today.
