Olga of Kiev
c. 890–925 — 969 · Feast day: July 11
The first Christian ruler of Kievan Rus, Olga governed as regent after the Drevlians killed her husband Igor in 945, then exacted systematic revenge on the tribe. Her baptism in Constantinople (c. 955–957) made her the first of Kiev's ruling dynasty to embrace Christianity. Her grandson Vladimir baptized all of Kievan Rus in 988, fulfilling what she had begun.
