Nineteen sixty-eight was an exceptional year in which people across the world mobilized in protest against imperialism, authoritarianism, and Cold War hegemony. The “Global 1968” has come to represent an era of social and political transformation, and its meaning has been debated into the twenty-first century. This chapter provides an overview of two major events that challenged the bipolar world order in 1968 – the Tet Offensive and the Prague Spring – and explores how the Vietnam War and Vietnamese people influenced protest movements around the world in this historic year. The Vietnamese communist revolution became a global symbol of anti-imperialism and Third World self determination, while South Vietnamese dissidents carried out protests for freedom and democracy that mirrored uprisings in other parts of the world.
