An overview of the British institutions and politics. Very didactic, but the edition I read (1986) of course is outdated by now (there are more recent ones!)
This book has at least one error: Bin Laden, al Qaeda, etc. are not Wahhabists.
Wahhabism is a fundamentalist version of Islam, and is also known as muwahhidun (unitarian) or Salafist (companions of the Prophet). It developed in Saudi Arabia mid 18th Century and reached the Trucial States (future UAE) around 1800. Saudi Arabia built Wahhabi mosques around the world in response to the 1979 Iranian (Shi’ite) revolution and increased Arab emigration. Saudi Arabia now supports 90% of the global costs of Islam, yet only contains 1% of Muslims. Bin Laden, al Qaeda, etc. are actually takfiris. Takfir essentially means excommunication. Muslims who oppose the takfiris are not considered true believers, and can therefore be killed. Takfir emerged from Egypt, not Saudi Arabia, and most victims of takfiri violence are Muslims
