Pan Tadeusz is an epic poem by the Polish-Lithuanian poet, writer and philosopher Adam Mickiewicz. The book was first published in June 1834 in Paris, and is considered by many to be the last great epic poem in European literature. The story takes place over the course of five days in 1811 and one day in 1812 at a point in Polish history, when Poland-Lithuania had already been divided between Russia, Prussia, and Austria and disappeared from the political map of Europe.
