Andrzej Wajda in the context of "Agnieszka Holland"

Pan Tadeusz (full title: Sir Thaddeus, or the Last Foray in Lithuania: A Nobility's Tale of the Years 1811–1812, in Twelve Books of Verse) is an epic poem by the Polish poet, writer, translator and philosopher Adam Mickiewicz. The book, written in Polish alexandrines, was first published by Aleksander Jełowicki on 28 June 1834 in Paris. It is deemed one of the last great epic poems in European literature.

Pan Tadeusz, Poland's national epic, is compulsory reading in Polish schools and has been translated into 33 languages. A film version, directed by Andrzej Wajda, was released in 1999. In 2014 Pan Tadeusz was incorporated into Poland's list in the UNESCO Memory of the World Programme.

Sir Thaddeus, or the Last Lithuanian Foray (Polish: Pan Tadeusz, czyli ostatni zajazd na Litwie), also simply known as Sir Thaddeus (Pan Tadeusz), is a 1999 film directed by Andrzej Wajda. It is based on the 1834 eponymous epic poem by Polish poet, writer and philosopher Adam Mickiewicz (1798–1855). As in the poem, conflict between the Soplica and Horeszko families serves as a backdrop for discussion of issues of Polish national unity and the struggle for independence.
