"Many of the most decisive turning points in the history of the world have been battles. More than just conflicts between armies, such moments often represent fundamental clashes among rival religions; cultures; and social, political, and economic systems. The outcomes of these battles have dramatically transformed and shaped the course of history, often sending it on unexpected or completely new paths. This course examines more than three dozen such pivotal moments, highlighting and exposing the key incidents and personalities responsible for these critical shifts. During the course of these lectures, we'll discover how the Battle of Yarmouk contributed to the establishment of Islam in the Middle East; how the Battle of the Talas River curbed the expansion of the Tang dynasty of China; how the Battle of Boyaca resulted in South American independence from Spain; and how the Battle of Khalkhin Gol, fought on the borders of Mongolia and Manchuria, influenced the entire direction of World War II in both Europe and the Pacific."--p. 1.
