Despite possibly going against the will of his father , Izyaslav was able to continue his rule in Polotsk . He was first to make Polotsk autonomous from the Grand Duke of Kiev passing his title to his descendants after his death . His principality carried a wide degree of autonomy that later was passed and to his descendants as well . His glory was commemorated after an established city that was named after him . Izyaslav died at the young age of about 23 , in 1001 , surviving his mother but predeceasing his father Vladimir of Kiev , thus excluding his descendants from ever succeeding the Kievan throne , according to the so - called '' ladder succession '' . The name of Izyaslav 's spouse is unknown . He had two sons : Bryachislav of Polotsk and Vseslav . Both were certainly minor at the time of his father 's death .
