High Quality Content by WIKIPEDIA articles! Polish literature is the literary tradition of Poland. Most Polish literature has been written in the Polish language, though other languages, used in Poland over the centuries, have also contributed to Polish literary traditions, including Yiddish, Lithuanian, Ukrainian, Belarusian, German and Esperanto. Until the early 18th century, a major language of Polish literature was Latin, widely popular across all of Western and Central Europe at the time.
