C1 World Dialogue is an initiative, whose stated mission is to “support and promote, propagate and preserve, peace harmony and friendship between the Western and Islamic Worlds”. The initiative has its origins in the Council of One Hundred Leaders (C-100) West-Islamic Dialogue originally launched by the World Economic Forum in response to the attacks of 11 September 2001 on the USA. Since then, the group has evolved into an autonomous body with an institutional base as a Swiss foundation, based in Basel. The president of the General Conference of the organization is former British Prime Minister Tony Blair.
