The prominence and influence of the Khazar state was reflected in its close relations with the Byzantine emperors: Justinian II (704) and Constantine V (732) each had a Khazar wife. The main source of revenue for the empire stemmed from commerce and particularly from Khazar control of the east-west trade route that linked the Far East with Byzantium and the north-south route linking the Arab empire with northern Slavic lands. Income that was derived from duties on goods passing through Khazar territory, in addition to tribute paid by subordinate tribes, maintained the wealth and the strength of the empire throughout the 9th century. But by the 10th century the empire, faced with the growing might of the Pechenegs to their north and west and of the Russians around Kiev, suffered a decline. When Svyatoslav, the ruler of Kiev, launched a campaign against the Khazars (965), Khazar power was crushed. Although the Khazars continued to be mentioned in historical documents as late as the 12th century, by 1030 their political role in the lands north of the Black Sea had greatly diminished. Despite the relatively high level of Khazar civilization and the wealth of data about the Khazars that is preserved in Byzantine and Arab sources, not a single line of the Khazar language has survived.
Svyatoslav I
▪ prince of Kiev
also spelled Sviatoslav , Russian in full Svyatoslav Igorevich
died 972
grand prince of Kiev from 945 and the greatest of the Varangian princes of early Russo-Ukrainian history.
He was the son of Grand Prince Igor, who was himself probably the grandson of Rurik, prince of Novgorod. Svyatoslav was the last non-Christian ruler of the Kievan state. After coming of age he began a series of bold military expeditions, leaving his mother, Olga (Olga, Saint), to manage the internal affairs of the Kievan state until her death in 969.
The Russian Primary Chronicle (Russian Primary Chronicle, The) (Povest vremennykh let) says that Svyatoslav “sent messengers to the other lands announcing his intention to attack them.” Between 963 and 965 he defeated the Khazars along the lower Don River and the Ossetes and Circassians in the northern Caucasus; he also attacked the Volga Bulgars. In 967 he defeated the Balkan Bulgars at the behest of the Byzantines, to whom he then refused to cede his conquest. He declared his intention of establishing a Russo-Bulgarian empire with its capital at Pereyaslavets (now Pereyaslav-Khmelnytsky) on the Danube River. In 971, however, his comparatively small army was defeated by a Byzantine force under the emperor John I Tzimisces, and Svyatoslav was compelled to abandon his claim to Balkan territory.
In the spring of 972, while Svyatoslav was returning to Kievan Rus with a small retinue, he was ambushed and killed by the Pechenegs (a Turkic people) near the cataracts of the Dnieper River.
Olga, Saint
▪ Russian saint and regent
also called Helga
born c. 890
died 969, Kiev; feast day July 11
princess who was the first recorded female ruler in Russia and the first member of the ruling family of Kiev to adopt Christianity. She was canonized as the first Russian saint of the Orthodox Church.
Olga was the widow of Igor I, prince of Kiev, who was assassinated (945) by his subjects while attempting to extort excessive tribute. Because Igor's son Svyatoslav was still a minor, Olga became regent of the grand principality of Kiev from 945 to 964. She soon had Igor's murderers scalded to death and hundreds of their followers killed. Olga became the first of the princely Kievans to adopt Orthodox Christianity. She was probably baptized (c. 957), at Constantinople (now Istanbul), then the most powerful patriarchate. Her efforts to bring Christianity to Russia were resisted by her son but continued by her grandson, the grand prince St. Vladimir (died 1015); together they mark the transition between pagan and Christian Russia.
Yaroslav I
▪ prince of Kiev
byname Yaroslav The Wise, Russian Yaroslav Mudry
born 980
died Feb. 2, 1054
grand prince of Kiev from 1019 to 1054.
A son of the grand prince Vladimir, he was vice-regent of Novgorod at the time of his father's death in 1015. Then his eldest surviving brother, Svyatopolk the Accursed, killed three of his other brothers and seized power in Kiev. Yaroslav, with the active support of the Novgorodians and the help of Varangian (Viking) mercenaries, defeated Svyatopolk and became the grand prince of Kiev in 1019.
Yaroslav began consolidating the Kievan state through both cultural and administrative improvements and through military campaigns. He promoted the spread of Christianity in the Kievan state, gathered a large collection of books, and employed many scribes to translate Greek religious texts into the Slavic language. He founded churches and monasteries and issued statutes regulating the legal position of the Christian Church and the rights of the clergy. With the help of Byzantine architects and craftsmen, Yaroslav fortified and beautified Kiev along Byzantine lines. He built the majestic Cathedral of St. Sophia and the famous Golden Gate of the Kievan fortress. Under Yaroslav the codification of legal customs and princely enactments was begun, and this work served as the basis for a law code called the Russkaya Pravda (“Russian Justice”).
Yaroslav pursued an active foreign policy, and his forces won several notable military victories. He regained Galicia from the Poles, decisively defeated the nomadic Pechenegs on the Kievan state's southern frontier, and expanded Kievan possessions in the Baltic region, suppressing the Lithuanians, Estonians, and Finnish tribes. His military campaign against Constantinople in 1043 was a failure, however.
Trade with the East and West played an important role in Kievan Rus in the 11th century, and Yaroslav maintained diplomatic relations with the European states. His daughters Elizabeth, Anna, and Anastasia were married respectively to Harald III of Norway, Henry I of France, and Andrew I of Hungary.
In his testament, Yaroslav sought to prevent a power struggle among his five sons by dividing his empire among them and enjoining the younger four sons to obey the eldest, Izyaslav, who was to succeed his father as grand prince of Kiev. This advice had no lasting effect, and civil war ensued after Yaroslav's death.
boyar
▪ Russian aristocrat
Russian Boyarin, plural Boyare,
member of the upper stratum of medieval Russian society and state administration. In Kievan Rus during the 10th–12th century, the boyars constituted the senior group in the prince's retinue ( druzhina) and occupied the higher posts in the armed forces and in the civil administration. They also formed a boyar council, or Duma, which advised the prince in important matters of state. In the 13th and 14th centuries, in the northeastern Russian principalities, the boyars were a privileged class of rich landowners; they served the prince as his aides and councillors but retained the right to leave his service and enter that of another prince without losing their estates.
From the 15th to the 17th century, the boyars of Muscovy formed a closed aristocratic class that surrounded the throne of the grand prince (later the tsar) and ruled the country together with him. They were drawn from about 200 families, descended from former princes, old Moscow (Moscow, Grand Principality of) boyar families, and foreign aristocrats. The rank of boyar did not belong to all members of these families but only to those senior members to whom the tsar granted this title. Below the boyars stood the group of okolnichy. Together these two strata formed the boyar council, which helped the tsar direct the internal and foreign affairs of the state. The decisions of the boyar council, as confirmed by the tsar, were recognized as the normal form of legislation. The boyars and okolnichy generally served as heads of government offices, provincial governors, and military commanders.
