Overview
Igor is a common East Slavic given name derived from the Norse name Ingvar, that was brought to ancient Rus' by the Norse Varangians, in the form Ingvar or Yngvar. Igor, the son of the Varangian chief Rurik, was left with Rurik's distant relative, first Grand Prince of Kiev Oleg, as a child. Igor after the death of Oleg replaced him on Kiev's throne. Outside of the Slavic language sphere, the name has also become common in Brazil and Portugal, and in the Basque-speaking part of Spain.
