her maternal grandfather, Christian August of Holstein-Gottorp.) Legacy Russian and Ukrainian historians have debated for many years about the legacy of the Rurikid dynasty. The Russian view sees the Principality of Moscow ruled by the Rurikid dynasty as the sole heir to the Kievan Rus' civilization, this view is "resting largely on religious-ecclesiastical and historical claims" because Russia was ruled by the Rurikid dynasty until 16th century, while Ukraine was not defined as a state until 20th century. This view started in Moscow as ruled by the original Rurikid dynasty between the 1330s and the late 1850s. The Ukrainian view was formulated much later, between the 1840s and the end of the 1930s in Eastern Austria, and views the Ukrainian descendants of the Rurikid dynasty as its only true successors. The Soviet theory was a modified version of the Russian which "allotted equal rights to the Kievan inheritance to the Three Slavic peoples, that is the Russians, the Ukrainians, and the Belorussians", but later elevated the Russian nation as the elder brother to give the others "needed guidance in revolutionary struggles and socialist construction." There are currently various extant branches of the Rurikids, for instance: the Houses of Shakhovskoy, Gagarin, and Lobanov-Rostovsky. Whose some of the representatives are: Prince Dmitriy Mikhailovich Shakhovskoy (born 1934), Prince Dmitri Andreevich Gagarin (born 1973) and Prince Nikita Lobanov-Rostovsky (born 1935), a descendant of Prince Konstantin Vasilyevich of Rostov. The three of them are of the Monomakhovichi branch. While the Shakhovskoys claim descent from Mstislav I of Kiev, the Gagarins, and the Lobanov-Rostovskys are descendants of Vsevolod III of Vladimir, which makes the Shakhovskoys the most senior.
