The book in question is called Poznaj Żyda, meaning “Meet the Jew”. Its cover features a common antisemitic caricature of a Jew in a variety of guises, suggesting that Jews are behind communism, the LGBT movement, the media, and various protest groups in Poland.
Despite the modern cover, it is a reprint of a 1912 book by conservative writer Teodor Jeske-Choiński. Its first chapter begins by describing Jews as a “parasitic tribe [that] has nested on our skin, sucks our sweat, our blood, for six centuries”.
The latest version has been published by Magna Polonia, a far-right media group. One of its leading figures, Przemysław Holocher, was recently invited to discuss the book in an interview on the YouTube by nationalist outlet Media Narodowe.
