Vsevolod III Yuryevich, or Vsevolod the Big Nest (Russian: III ) (1154 1212), was the Grand Prince of Vladimir during whose long reign (1177 1212) the city reached the zenith of its glory. Vsevolod was the tenth or eleventh son of Yuri Dolgoruky, who founded the town Dmitrov to commemorate the site of his birth. Nikolai Mikhailovich Karamzin was the first to speculate that Vsevolod''s mother Helene was a Greek princess, for after her husband''s death she took Vsevolod with her to Constantinople. It was at the chivalric court of the Komnenoi that he spent his youth. On his return from the Byzantine Empire to Rus in 1170, Vsevolod supposedly visited Tbilisi, as a local chronicle records that that year the Georgian king entertained his nephew from Constantinople and married him to his relative, an Ossetian princess.
