Birth of the TsardomPolitical
Ivan IV is crowned tsar of all Russia
In the Dormition Cathedral of the Moscow Kremlin, the sixteen-year-old grand prince Ivan IV is crowned tsar, the first ruler of Moscow to take the imperial title formally.
The title tsar derived from the Latin 'caesar' and signaled that Moscow now claimed the heritage of the Orthodox emperors of Constantinople. The coronation transformed a grand principality into a tsardom and gave ideological form to a century of Muscovite expansion and centralization.
