This is a concise and easily accessible introduction to early Islamic political history. While not the most nuanced or up-to-date work, it's a good general survey for the layperson. It may serve as a springboard for more complex and in-depth works. I must say, however, that the title is unfortunate.

This survey is a model of fine scholarship and brevity. In less than 200 pages Gibb provides an appreciation of Islam and describes the major sects and movements.

The survey suffers only from its age (otherwise 5 stars). It was written in 1947 and revised a few times, lastly in 1970. The author died shortly thereafter. Some terms are outdated, not the least of which is the title "Mohammedanism". Some Muslims may regard the title offensive since it implies primacy of Mohammed rather than God. Gibb is aware of this and speaks to it. Perhaps owing to the less charged environment of his day he stuck with this western term on the basis that some muslim sects described themselves as followers of Mohammed.

Today's reader should not infer from the title that the book is an oafish, chauvinistic view. Gibb communicates the compelling message of early Islam and illuminates the remarkable development of Islamic law and culture. The Shi'ia split and Sufism are explained in clear but nuanced treatments.

I have read more recent and lengthier texts on Islam and the Arab world. Few have demonstrated the admirable qualities of Islam as effectively as this short book.

The vision of the muslim past is a source of enormous power and inspiration in the Arab world today. The vast majority harness it to positive ends to shape their everyday conduct. But it clearly can be husbanded for evil purposes - just read bin Laden's fatwas.
