Mahmoud Ahmadinejad (born 28 October 1956) is an Iranian politician who was President of Iran from 2005 to 2013.
In 2006, the International Conference to Review the Global Vision of the Holocaust was held in Iran. There was also the Holocartoons website and the International Holocaust Cartoon Competition.
Ahmadinejad himself has been accused of "Holocaust denial", is stated to have called the Holocaust a "myth", but what exactly he meant may be unclear, with there being various kinds of criticisms of the Holocaust.
The context has been the conflict with Israel, support by Iran for the Muslim Palestinians, and use of the Holocaust by Zionists, rather than part of support for general freedom of speech by the Islamist Iran.
Later Iranian leaders have apparently not repeated the "myth" statement, although stated to sometimes have expressed certain skepticism.
