The history of agrarian reform is as long as the history of the world, extending back into medieval, ancient, and biblical times. Like many other socio-economic and political movements, agrarian reform movements have been sporadic and discontinuous, although the last two centuries have witnessed almost continuous reform attempts commencing with the French Revolution. These attempts have become very common during the last two decades and have become part and parcel of United Nations programs. Though the literature on reform is extensive, there has been no endeavor to review reform movements in a historical perspective, or to synthesize the knowledge that can be derived therefrom and utilize it in guiding or evaluating reform. The need for this cannot be overestimated.
