After the war, in September 1814 Mikhailovsky-Danilevsky was a member of the Russian delegation at the Congress of Vienna and remained until its end in June 1815.
Nadezhda Lappo-Danilevsky (born in 1874, Kiev, Russian Empire - died on March 17, 1951, Charolais, Department of Saône-et-Loire, France) was a Russian writer and a member of Russian apostolate.
Born into the family of an impoverished landowner, Petr Ivanovich Danilevsky, in the Izyumsky district of Sloboda Ukraine, Grigory was educated in the Moscow Dvoryansky institut (Institute of the Nobility) from 1841 to 1846, then studied law at Saint Petersburg University.
Danilevsky first published "Russia and Europe: a look at the cultural and political relations of the Slavic world to the Romano-German world" in the journal Zarya in 1869.
This, according to biographer Yuri Zobnin, distinguished it from other Russian historical novels, set in the tradition once started by Danilevsky.
