The seventeenth-century chronicles record an interesting event under the year 1574:At that time Tsar Ivan Vasil'evich enthroned Simeon Bekbulatovich as tsar in Moscow and crowned him with the crown of the tsars, and called himself [simply] Ivan of Moscow; he left the city and lived in Petrovka. All the offices of tsardom he passed to Simeon, and himself rode simply, like a boyar with shafts, and whenever he comes to Tsar Simeon, he sits at a distance from the Tsar’s place, together with the boyars.That such an event did in fact take place, we have the testimony of contemporary witnesses, the English envoy Danyell Silvester and the imperial envoy Daniel Printz a Bucchau, as well as official documents which have been preserved from the time of Simeon’s reign as tsar.
