The International Conference to Review the Global Vision of the Holocaust was a two-day conference that opened on December 11, 2006, in Tehran, Iran. Iranian Foreign Minister Manouchehr Mottaki said the conference sought "neither to deny nor prove the Holocaust... [but] to provide an appropriate scientific atmosphere for scholars to offer their opinions in freedom about a historical issue." Notable attendees included David Duke, Moshe Aryeh Friedman, Robert Faurisson, Gerald Fredrick Töben, Richard Krege, Michèle Renouf, Ahmed Rami and Yisroel Dovid Weiss of Neturei Karta.
The conference was widely described as a "Holocaust denial conference" or a "meeting of Holocaust deniers".
The conference provoked criticism. The Vatican condemned it, the US administration of President George W. Bush called it an "affront to the entire civilized world," and British Prime Minister Tony Blair described it as "shocking beyond belief." Holocaust historians attending a separate conference in Berlin organized in protest against the Iranian one called it "an attempt to cloak anti-Semitism in scholarly language."
According to the Iranian Foreign Ministry, the conference would not aim to deny or prove the Holocaust, but to create opportunities "for suitable scientific research so that the hidden and unhidden angles of this most important political issue of the 20th century becomes more transparent." The event was organized by the ministry's Institute for Political & International Studies] (IPIS).
