Olga
945-964 Prince Svyatoslav
964-972 93 years Rus grew as both a trading empire
and a military power, with Oleh’s armies attacking Constantinople and gaining a favorable trade treaty from the Greek rulers of that city in 911 Igor (912–945) was less successful in his military campaigns against Constantinople and also had to contend with rebellions among the Slavic tribes who did not want to pay tribute to the rulers in Kiev.
Olga
945-964 Prince Svyatoslav
964-972 93 years Princess Olga took revenge for her husband’s
death. Olga served as regent (945–962) for their son, Svyatoslav. She is favorably portrayed in the old chronicles, perhaps because of her conversion to Christianity, but also because she reestablished control over the various tribes and put the realm’s financial standing in good order.
