This article looks at the intersection between contraband and violence in Southeast Asia. I argue that the two activities are often linked and play off one another in specific, contextualized ways. To make this case, I examine instances of smuggling in the history of the region; through the trade in human beings, both historically and today; through the transit of narcotics, again historically and today; and via the conduit of a range of other contraband cargoes. Race, religion, memory and geography all factor into the outcome of when smuggling may take on violent forms. I chronicle these occasions throughout the width and breadth of the region, stretching from the Thai/Burmese border in the north to the island world of Insular Southeast Asia in the south. Throughout the essay, I pay particular attention to the larger milieus of commerce, politics, and society that condition moments when acts of smuggling may in fact turn violent.
