Adam Bernard Mickiewicz (1798–1855) was a Polish poet, dramatist, essayist, publicist, translator, professor of Slavic literature, and political activist. He is regarded as national poet in Poland, Lithuania and Belarus. A principal figure in Polish Romanticism, he is counted one of Poland's "Three Bards" ("Trzej Wieszcze") and is widely regarded as Poland's greatest poet. He is also considered one of the greatest Slavic and European poets and has been dubbed a "Slavic bard". A leading Romantic dramatist, he has been compared in Poland and Europe to Byron and Goethe.
