Anna Porphyrogenita[a] (Greek: Άννα Πορφυρογέννητη) (13 March 963 – 1011)[1] was the grand princess consort of Kiev during her marriage to Vladimir the Great.
Vladimir was impressed by Byzantine religious practices; this factor, along with his marriage to Anna, led to his decision to convert to Eastern Christianity.
Anna participated actively in the Christianization of Rus': she acted as the religious adviser of Vladimir and founded a few convents and churches herself.
[4] Furthermore, French historian, Jean-Pierre Arrignon argues that Yaroslav the Wise was indeed Anna's son, as this would explain his interference in Byzantine affairs in 1043.
[6] This view is corroborated by the study of Yaroslav's remains carried out in 1939–1940, as well as his age given in the Primary Chronicle, which would place him amongst Vladimir's youngest children (with 988–990 as his estimated date of birth).
