In 1984, during his studies at the University of Warsaw, he joined SFAN science fiction fan association and started writing short stories. His first science-fiction short story was published in 1982. His book debut was Władca szczurów,. He also worked for two Polish science-fiction magazines: Fantastyka and as a chief editor for Fenix, and collaborated with an underground publishing house "STOP" by distributing its books at the Department of Polish, University of Warsaw. In the 1990s, he became one of the most popular Polish science-fiction authors. For his novels Pieprzony los kataryniarza and Walc stulecia, as well as his short story Śpiąca królewna, he was awarded the Zajdel Award, the most prestigious Polish award for science fiction and fantasyliterature. He was also awarded Śląkfa for Writer of a Year in 1990 and 1998. A popular theme in his works is the fate of Poland and more broadly, Europe, in the near future. His books often paint the future in dark colors, showing the Commonwealth of Independent States disintegrate into a civil war, European Union becoming powerless in the face of Islamic terrorism, and predatory capitalism and political correctness taken ad absurdum leading to the erosion of morality and ethics. Thus his books are often classified as political fiction and social science fiction, although they are not seen as dystopian fiction.
Journalist and publicist
After the fall of communism, Ziemkiewicz became a conservative journalist and essayist. He began this career in the early 1990s as a publicist for Najwyższy Czas! weekly magazine. Until February 1997, Ziemkiewicz wrote political and socio-economical essays for Gazeta Polska. He was also a columnist of popular Polish magazine Wprost and the Polish edition of Newsweek, and occasionally published essays in Polityka. Currently his columns are being published in Rzeczpospolita, Uważam Rze, Gazeta Polska, Niezależna Gazeta Polska and Interia.pl webportal. Many of his essays have been collected and published in book format. In 2001 he won the Kisiel Prize. He has also worked as a radio journalist, working for Radio WAWA and Polskie Radio Program IV in the 1990s, Radio TOK FM in the early 2000s, later with Radio VOX FM and Program 1 Polskiego Radia. He hosts a television talkshow on TVP Info and a program on TVP Historia. He was a spokesman for the Real Politics Union party. In 1995, as a stipendiary of the National Forum Foundation he worked for the Republican Party in United States. In September 2006, Ziemkiewicz published an article in the Polish edition of Newsweek criticizing the editor-in-chief of Gazeta Wyborcza, Adam Michnik; Michnik brought a civil suit against Ziemkiewicz, which was settled in 2007 after Ziemkiewicz agreed to publish an apology. In 2018, he cancelled a planned speaking tour in the UK following appeals by activists and politicians to the Home Office to block his entry due to hate speech concerns. In 2020, he published a book titled "Cham niezbuntowany". The anti-racist watchdog said that the book contained examples of criminal hate speech, such as when it describes Israeli children as being molded into "killing machines" and calls the Holocaust a "myth". According to Gazeta Wyborcza, "the book propagates anti-Semitic views that are intended to incite hatred of Jews". The Jerusalem Post described Ziemkiewicz's views in the book as being antisemitic.
