A brief historical primer on Islam

I am admittedly not very knowledgeable about the history of Islam.

Today’s OpinionJournal.com has a fascinating overview of Islamic imperial history, Islam’s Imperial Dreams. It is written by Efraim Karsh, and based on a new book he has authored call Islamic Imperialism: A History.

I’ve become quite concerned about radical Islam over the past few years. The more I learn, the more I wonder if “radical Islam” is redundant.
