Dhimmitude: the Islamic system of governing populations conquered by jihad wars, encompassing all of the demographic, ethnic, and religious aspects of the political system. The word "dhimmitude" comes from dhimmi, an Arabic word meaning "protected". Dhimmi was the name applied by the Arab-Muslim conquerors to indigenous non-Muslim populations who surrendered by a treaty (dhimma) to Muslim domination. Islamic conquests expanded over vast territories in Africa, Europe and Asia, for over a millennium (638-1683). The Muslim empire incorporated numerous varied peoples which had their own religion, culture, language and civilization. For centuries, these indigenous, pre-Islamic peoples constituted the great majority of the population of the Islamic lands. Although these populations differed, they were ruled by the same type of laws, based on the shari'a.

Wahhabism: (sometimes spelled Wahabbism or Wahabism) is a movement of Islam named after Muhammad ibn Abd al Wahhab (1703–1792). It is a fundamentalist movement of the Sunni form of Islam and has become an object of increased interest because it is the major sect of the government and society of oil-rich Saudi Arabia, and claimed to be followed by Osama bin Laden, who was raised in Saudi Arabia. Wahhabism is an offending synonym for Salafism.
The spread of Wahhabi Islam has been facilitated by Saudi oil revenues; Saudi laypeople, government officials and clerics have donated many tens of millions of dollars to create Wahhabi-oriented religious schools, newspapers and outreach organizations.
