The introduction puts the topic of Vietnam War protest into a global context. It briefly reviews relevant literature on protest in the era of the Indochina Wars and explains why the Vietnam War (or Second Indochina War) was so significant globally in terms of mobilising mutually interlinked liberation struggles, social movements, protest, and solidarity activities in different parts of the globe, harking back to the 1950s and fully unfolding during the second half of the 1960s. The historiographical inspiration for the entire volume is to shift our focus away from established perspectives that are thoroughly focused on US history with only peripheral attention paid to other parts of the world. The United States is thus no longer seen as the centre and origin of dissent that eventually spread outwards, making way for a more complex understanding of the interplay between the different world regions in the global emergence of protest.
