I was weaving through the industrial backstreets of Kyiv port the other day when I found a painted mural depicting Olga of Kyiv, a powerful 10th-century pagan queen. Patriarchal Orthodox history says that late in life she converted to Christianity. However, if that was the case it is likely to have been for political and/or matrimonial reasons.  She is most remembered for her ruthless military campaign which defeated and subjugated the Drevelians, a Slavic tribe who had assassinated her husband Igor and threatened to destroy her Kyivan Rus empire.
