In this book, a leading authority on Iranian political parties offers the first history of the Mojahedin, a little-known radical group that was instrumental in bringing the Ayatollah Khomeini to power but that now constitutes the main opposition to his Islamic Republic. Drawing on all available sources-including interviews with past and present members of the Mojahedin-Ervand Abrahamian traces their organization from the 1960s to the present. "[This] book is important and useful not only because it is the first in English on its subject, but also because ...it is objective...[I]ts approach is thoughtful, fresh and independent, being to Islam more or less what liberation theology is to Christianity."-Economist "Abrahamian's commentary on Ali Shariati and his relationship to the Mojahedin is a unique and impressive achievement...Radical Islam is a learned, lucid and cogent piece of Iranian history...The book is must reading for all experts and observers interested in the politics of the Islamic Revolution and the role of Iran's political culture."-Mansour Farhang, Middle East Report "The result is one of the best of so many books about Iran today."-A. R. H. Kellas, Asian Affairs "This is the most objective and comprehensive study available of the important Iranian movement."-Anthony Hyman, International Affairs
