What are the reasons for the Arab conquests.

The reason for the Arab conquests was the desire to spread Islam and defeat the unbelievers. Thus, from 632 the Arabs begin their war. The conquests of the Arabs took place not only in the Middle East, but also in North Africa, and even in Europe. Arab rule spread to many regions. Because of them, the Frankish kingdom was forced to start a war with the Arabs who were advancing through the lands of Spain. During its heyday, the Arab Caliphate included vast territories of the East, North Africa and the lands of Spain.
