Islamic world, the complex of societies and cultures in which Muslims and their faith have been prevalent and socially dominant.
Adherence to Islam is a global phenomenon: Muslims predominate in some 30 to 40 countries, from the Atlantic eastward to the Pacific and along a belt that stretches across northern Africa into Central Asia and south to the northern regions of the Indian subcontinent. Arabs account for fewer than one-fifth of all Muslims, more than half of whom live east of Karachi, Pakistan. Despite the absence of large-scale Islamic political entities, the Islamic faith continues to expand, by some estimates faster than any other major religion.
The Muslim religion and the life of the Prophet Muhammad are treated specifically in the article Islam. The literature, music, dance, and visual arts of Muslim peoples are treated in the article Islamic arts. Islam is also discussed in articles on individual countries or on regions in which the religion is a factor, such as Egypt, Iran, Arabia, and North Africa. See articles on individual branches or sects and concepts—for example, Islam, Nation of; Sunni; Shiʿi; Hadith.
A very broad perspective is required to explain the history of today’s Islamic world. This approach must enlarge upon conventional political or dynastic divisions to draw a comprehensive picture of the stages by which successive Muslim communities, throughout Islam’s 14 centuries, encountered and incorporated new peoples so as to produce an international religion and civilization.
