Yaroslav The Wise - Reign

Reign

Leaving aside the legitimacy of Yaroslav's claims to the Kievan throne and his postulated guilt in the murder of his brothers, Nestor the Chronicler and later Russian historians often presented him as a model of virtue, styling him "the Wise". A less appealing side of his personality is revealed by his having imprisoned his younger brother Sudislav for life. Yet another brother, Mstislav of Tmutarakan, whose distant realm bordered the Northern Caucasus and the Black Sea, hastened to Kiev and, despite reinforcements led by Yaroslav's brother-in-law King Anund Jacob of Sweden (as Jakun - "blind and dressed in a gold suit"), inflicted a heavy defeat on Yaroslav in 1024. Yaroslav and Mstislav then divided Kievan Rus' between them: the area stretching left from the Dnieper, with the capital at Chernihiv, was ceded to Mstislav until his death in 1036.

In his foreign policy, Yaroslav relied on the Scandinavian alliance and attempted to weaken the Byzantine influence on Kiev. In 1030, he reconquered Red Rus' from the Poles and concluded an alliance with King Casimir I of Poland, sealed by the latter's marriage to Yaroslav's sister Maria. In another successful military raid the same year, he founded Yuryev (today Tartu, Estonia) (named after Saint George, or "Yury", Yaroslav's patron saint) and forced the surrounding province of Ugaunia to pay annual tribute.

In 1043, Yaroslav staged a naval raid against Constantinople led by his son Vladimir and general Vyshata. Although the Rus' navy was defeated, Yaroslav managed to conclude the war with a favourable treaty and prestigious marriage of his son Vsevolod to the emperor's daughter. It has been suggested that the peace was so advantageous because the Kievans had succeeded in taking a key Byzantine possession in Crimea, Chersones.

To defend his state from the Pechenegs and other nomadic tribes threatening it from the south he constructed a line of forts, composed of Yuriev, Boguslav, Kaniv, Korsun, and Pereyaslav. To celebrate his decisive victory over the Pechenegs in 1036 (who thereupon never were a threat to Kiev) he sponsored the construction of the Saint Sophia Cathedral in 1037. Other celebrated monuments of his reign, such as the Golden Gates of Kiev, have since perished.

Yaroslav was a notable patron of book culture and learning. In 1051, he had a Russian monk Ilarion proclaimed the metropolitan of Kiev, thus challenging old Byzantine tradition of placing Greeks on the episcopal sees. Ilarion's discourse on Yaroslav and his father Vladimir is frequently cited as the first work of Old Russian literature.
