Dar-al-Islam: the sources and the processes of the unification
The article deals with the spread of Islam in the African-Asian region, the beginning and development of this process, different religious centres formation and the uprise of Muslim dynasties. It also deals with the ethnic situation in the emerging Muslim world, which was politically fragmented, but still unified not just through religion, but also through cultural traditions, ways of life and philosophy. The paper analyses the cultural and ethnic synthesis, which appeared in the Muslim world practically at the same time with the spread of religion.
