PreRussia - стр. 4
The incorrectness of the official date of the emergence of Russia is confirmed even by the fact that the first "official and reliable" mention of the Russian state in foreign chronicles, recognized in the West, falls on the year 839. That is 23 years before the coming of Rurik. There is a mention in the Bertin Annals (the chronicle of the Saint-Bertin monastery in France) that the ambassadors of the Ross people arrived to the Byzantine emperor Theophanes in 839 to establish diplomatic and trade relations and that their ruler was a Khagan. Here the title of the ruler is somewhat surprising, but the Russian Khaganate apparently existed indeed as it is written below. The Arabs and sometimes the Slavs themselves (on especially solemn occasions) called the prince of Kiev by the word Khagan up to and including the X century (possibly under the influence of the Khazar Khaganate). Whether these ambassadors came from Novgorod, Kiev, Ladoga or another part of Russia is unclear.
Thus, long before the advent of Rurik the Russian state had already been establishing diplomatic and trade missions with the neighboring countries. The material collected by several generations of individual Russian scientists indicates that the age of Russian statehood is about the same as that of Ancient Rome and Ancient Greece. Although this point of view has not yet been officially recognized, it is gaining more and more supporters among scientists over time.
Mikhail Vasilyevich Lomonosov, in his work "Ancient Russian History from the beginning of the Russian people to the death of Grand Duke Yaroslav the First or until 1054," was resolutely against the "Norman" theory and wrote "about the distant antiquity of the Slavic people." Here is a quote from the 6th volume of his complete works (Moscow, Leningrad, 1952).
"At the beginning of the sixth century after Christ, the Slavic name became very famous; and the power of this people was not only terrible in Thrace, Macedonia, Istria and Dalmatia, but also contributed very much to the destruction of the Roman Empire. The Vends and Ants, uniting with their kindred Slavs, multiplied their strength. The unity of these peoples is not only shown by the current similarity in languages, but is also testified twelve hundred years ago by Iornand, who left the message that "from the beginning of the Vistula River to the north, there are populous Vendian peoples living in an immeasurable space, whose names, although different for different generations and places, but the Slavs and Ants are generally called." He also adds that from the Vistula they extend to the Danube and to the Black Sea. Before him, Ptolemy in the second century by Christ places the Vendians near the entire Vendian Bay named after them, that is, near the Finnish and Kurland bays. This author, moreover, let us know that Sarmatia was taken over by the great Vendian peoples. And Pliny also testifies that in his time the Vendians and Sarmatians lived near the Vistula… So, the Slavic-polish people justly call themselves Sarmatian; and I will not hesitate to conclude with Kromer that the Slavs and the Vendians in general are ancient Sarmatians… About antiquity [of the Slavs, – translator’s remark] we have a satisfied and almost obvious assurance in the greatness and power of the Slavic tribe, which has been standing on almost one measure for more than a thousand and a half years; and it is impossible to imagine that in the first century after Christ, it suddenly multiplied to such a great multitude..".
