Conflict and Cooperation: Documents on Modern Global History, second edition, is a collection of primary documents for the study of twentieth- and twenty-first-century history. The twentieth century was profoundly shaped by war. We saw, for the first time in human history, the possibility of a war that could destroy all human life on earth. However, this was also the century that witnessed genuine attempts to build cooperative global institutions designed to prevent war, to facilitate international communication, and to improve the human condition. Conflict and cooperation are the defining themes that weave together this collection of primary documents. The readings have been selected with the goal of making twentieth-century history accessible to students for whom these events are increasingly distant. The second edition of Conflict and Cooperation significantly expands the documents presented. Most importantly, the collection now features key documents related to technology and the environment. As well, important documents on Latin America and on the Islamic world have been included. The primary documents allow readers to "witness" essential moments in history through the words of the men and women who participated in and experienced these events.
