European governments and media have responded to his visits. During his speaking tour in Hungary in 2014, Spencer was mocked by the Hungarian newspaper for his call for "a white Imperium" through a revival of the Roman Empire, and for his claim to be a "racial European", ideas that the newspaper called contrived and without any basis in European history. In the aftermath of his visit, Hungarian Prime Minister Viktor Orbán pressed through legislative measures which banned his entry and condemned Spencer. The government of Poland has also banned him from entering the country and condemned Spencer, citing his Nazi rhetoric, the anti-Polish and anti-Slavic racism of the Nazis, and the Nazis' genocide of Slavic peoples during World War II. In July 2018, Spencer was detained at Keflavík Airport in Reykjavík, Iceland en route to Sweden and was ordered by Polish officials to return to the United States; the successful effort of the Poles to ban Spencer from other parts of Europe arises from the Schengen Agreement.
