Colonial archaeology in Southeast Asia examines the impact of European powers from the 16th to mid-20th centuries. It explores how colonization transformed political, economic, and social structures, leaving lasting legacies in the region's built environment, cultural identities, and heritage. Key sites like Angkor Wat, Bagan, and Malacca offer insights into pre-colonial and colonial periods. Artifacts, including ceramics and religious objects, reveal cultural exchanges and adaptations. Research methods combine excavations, historical analysis, and community engagement to uncover complex colonial interactions.
