In recent decades the western Pacific has been the site of considerable violent conflict and instability. The region has played host to a ten-year secessionist struggle on Bougainville in Papua New Guinea (PNG), a five-year low-level civil war in neighbouring Solomon Islands, a resurgence of localised armed conflict in parts of the PNG Highlands, and a number of less serious episodes of social unrest in Vanuatu and New Caledonia. These conflicts, along with those in Indonesia on the region’s western edge and in Fiji at its eastern fringe, have given rise to depictions of the region as an ‘arc of instability’ inhabited by states at various stages of ‘failure’.
Meanwhile, sovereignty, in the sense of constitutional independence and recognition by other states in the international Westphalian system of nation-states, remains much contested in various parts of contemporary Oceania (Firth 1989; Levine 2012). Indeed, the region hosts a bewildering range of “asymmetrical” autonomy arrangements, almost all of which have been negotiated between metropolitan powers and their former colonial territories, reflecting both the extent to which island jurisdictions have provided “rich breeding grounds for unique adaptations of governance” (Baldacchino and Milne 2009:5) and the highly negotiated, contingent and relational nature of sovereignty practices in the contemporary world (Martin 2014).
In the case of the western Pacific, the culture area known as Melanesia, the quest for full sovereignty, or independence, has been most striking in the Indonesian province of West Papua and in the French overseas territory of New Caledonia. The on-going, and, at times, violent struggles for independence in these two cases have been, in large measure, struggles for ethnic liberation; and could, therefore, be seen as manifestations of a classic form of identity-based nationalism in the context of anti-colonial struggle.
However, important as these two cases are, the focus of this chapter is not upon the international/Westphalian dimensions of sovereignty. Nor is it concerned with the evolving relations between former colonial territories and the metropolitan powers with which they remain constitutionally connected. Rather the geographical focus is upon post-colonial Melanesia and the conceptual focus is upon sovereignty defined in terms of the state’s supreme authority over the entirety of its national territory; or, in other words, on “internal” as opposed to “external” sovereignty (Gregory et al. 2009: 706).
This form of sovereignty has been, and continues to be, deeply problematic across post-colonial Melanesia where ethno-nationalist, or “micro-nationalist” (May 1982), agendas have loomed large in the panoply of political struggles, often of a violent nature, that have challenged the authority and legitimacy of the central state since the early days of colonial incursion. In this sense, then, my focus in this chapter is upon what we might call sub-national challenges to the territorial sovereignty of the post-colonial state in Melanesia and their intersections with ethnic identity and violent conflict. I will take as my primary focus the region known to geographers as the Solomons chain of islands consisting of the Autonomous Region of Bougainville and the independent nation-state of Solomon Islands. These islands have played host to the two most serious armed conflicts that the western Pacific has witnessed since the Second World War, conflicts in which the scale of the island, as a sub-national level of governance (i.e. province), became a powerful, albeit problematic, platform for the mobilisation of ethnic identities in the pursuit of political objectives.
