About this Lecture


This module covers events from November 1963, when Lyndon Johnson succeeded John F. Kennedy as US President to the end of 1967, by which point the number of US troops had climbed above 400,000. As we move through the module, we consider the events that led up to the first ground troops arriving in Vietnam, including the Gulf on Tonkin incident, as well as the military strategies and tactics pursued by both the Americans and the Viet Cong in the following four years.


In this course, Dr Patrick Hagopian (University of Lancaster) explores the history of the Vietnam War, from Ho Chi Minh's Proclamation of Independence in September 1945 to the Fall of Saigon at the end of April 1975. In the first module, we attempt to explain why the United States was interested in Vietnam at all. After that, we consider the period between 1956-63, when the United States decisively threw its support behind the government of Ngo Dinh Diem, ending with Diem's overthrow and assassination on 2 November, 1963. In the third module, we continue to story as Lyndon B. Johnson replaces the assassinated John F. Kennedy and proceeds to escalate the war in Vietnam until—at the end of 1967—the US had committed some 400,000 combat troops to the region. In the fourth module, we focus on one of the most pivotal moments in the war—the Tet Offensive—in which some 80,000 Viet Cong launched a series of surprise attacks on targets throughout South Vietnam. After that, we turn to President Nixon's management of the war and his policy of Vietnamization, a program to "expand, equip, and train South Vietnam's forces and assign to them an ever-increasing combat role, and the gradual withdrawal of US troops from the region. Finally, in the sixth module, we turn to the final years of the war, including the signing of the Paris Peace Accords and the final fall of Saigon in April 1975.


Patrick Hagopian is currently Senior Lecturer in the History Department at Lancaster University. After obtaining his BA in American Studies at Sussex University, Hagopian did his postgraduate work in the United States, where he studied Communications (MA, Pennsylvania) and History (PhD, Johns Hopkins). He then took up a postdoctoral fellowship in American Material Culture at the College of William and Mary, Williamsburg, Virginia, before returning to teach American Studies in Britain.

Patrick's research interests are in American memory (the representation of the past in museums and public monuments, popular expressions of the past in oral histories, and the intersection between individual memory and communal representations of the past); the Vietnam War; and military justice and international law.
