The Oecusse-Ambeno enclave of Timor has persisted as a geographically distinct zone under Portuguese governance for over three centuries, enduring repeated efforts to undo its enclave status. This article analyses the confluence of economic, religious, and political elements that brought and kept Oecusse within Portuguese rule on Timor. Strong local authorities controlled trade linkages, maintained political and military ties with colonial rule, and wove Catholicism into existing customary practices and hierarchies, forging a strong regional identity that fostered sustained alliance with the Portuguese. Finally, the article discusses the impacts of Oecusse's enclave status over the past century.

The understanding of Angkorian pre-state society has been greatly enhanced by an increase in archaeological investigation in recent years. From excavations conducted at Cambodian Iron Age sites we have evidence that attests to a transformative period characterised by increasing sociopolitical complexity, intensified inter- and trans-regional mercantile activity, differential access to resources, social conflict, technological transfer and developments in site morphology. Among the growing corpus of Iron Age sites excavated, Phum Lovea, on the periphery of Angkor, is uniquely placed to provide insight into increasing sociopolitical complexity in this area. The site is one of the few prehistoric moated settlements known in Cambodia and the only one to date to have been excavated. Excavation of the site has revealed an Iron Age agrarian settlement whose occupants engaged in trade and exchange networks, craft specialisation, metal production, and emergent water management strategies. These attributes can be seen as antecedent to the profound developments that characterise the first millennium CE polity centred on Angkor.

Archaeological data over the past two decades have contributed to our understanding of the transition into the historic period in Southeast Asia and rebutted outdated models of externally stimulated complex polity formation. This article investigates the transition into the Pre-Angkorian period 300–500 CE based on a model constructed using archaeological data from Thala Borivat, Cambodia. Data from Thala Borivat suggest a pattern of continuity where smaller proto-historic settlements may have become incorporated c.300–500 CE into larger ones which became major Pre-Angkorian centres. This phenomenon coincided with evidence of increasing inter- and intra-regional interaction following the proto-historic period. This article argues that the model can be used to reinterpret the pattern observed in major Pre-Angkorian centres in the Mekong Delta and northeast Thailand. This pattern is complemented by the spatial correlation between the chronometrically-anchored ceramic traditions in proto-historic and early historic period Cambodia that suggests the continuity of local communities. Spatial correlation between prehistoric sites and inscriptions recording Pre-Angkorian elites, particularly the poñ, mratāñ, and kings provides similar patterns of continuity between the elites of the late proto-historic to the Pre-Angkorian periods.

Linking the early historic cultures of Southeast Asia to their prehistoric antecedents has, despite some decades of research, proved difficult for a number of reasons. Until the 1960s, this did not seem to be an issue for scholars of the region. For George Coedès, the region was simply occupied by diverse and backward ethnic and linguistic communities, cultivators using stone tools, or at best, people using bronze with poorly developed social organisations until impacted by the expanding Han peoples during the third century CE: ‘There is very little direct information about the societies of South East Asia before they entered into contact with India and China.’
