There was a time when Muslims, led by the Arabs, Persians and Turks had a mighty empire that spread over vast areas of Asia, Africa & Europe. This empire, that was inspired by the Islamic faith, came to an end early in the twentieth century. The aftermath of its downfall had a drastic impact on the Muslim world, particularly the Arabs. Were Muslims themselves to be blamed for its failure, or was it their Islamic faith that could not deliver its promises ?

This is a summary of what has happened to the  Arab and Islamic communities for the last 1400 years. 
Full details are in my book  'Islam under the microscope of the Free Mind' .
