Uglich is the site of one of Russian history's most famous murders. The male child of Ivan the Terrible, who may have succeeded to the throne had his older brother bore no sons, was found dead in Uglich in 1591. Dmitri was only a boy at the time, and though his death might have been an accident, it is likely that Boris Godunov had Dmitri killed to prevent him from ever claiming the throne. The murder instigated the appearance of several so-called False Dmitris who were sometimes supported by those who wanted power for themselves or instability in Russia.
Boris Godunov order the clapper of the bell that announced Dmitri's death to be removed, whipped, and banished to Siberia as punishment. The bell in Uglich remains tongueless to this day.
