The events of the "Arab Spring" took the world by surprise. Yet, the roots of those rebellions run deep and nowhere more so than in Syria, where the fighting continues to be fierce and deadly. This month, Fred H. Lawson traces the history of one leading force in the ongoing Syrian uprising: the Syrian Muslim Brotherhood. The Brothers led a violent campaign to overthrow the Syrian regime in the 1970s, but more recently have advanced a platform that calls for liberal reform and constitutional government. Whatever the outcome of the current struggle, the Muslim Brotherhood is certain to play a central role in Syria's future.
