Maritime archaeology studies the human past through submerged material remains—shipwrecks, harbors, coastal settlements, and underwater landscapes. The central challenge is not simply locating and excavating these sites but deciding what questions to ask of them. Should a wreck be treated primarily as a time capsule of artifacts that reveals a cultural group's identity? As a system of technological and economic behavior? As a site of contested meanings and identities? The answers have shifted dramatically over the past century as five major frameworks have shaped the subfield, each bringing different assumptions about evidence, interpretation, and whose stories matter.
The earliest systematic framework in maritime archaeology was Culture-Historical Archaeology, which dominated from the early 1900s through the 1960s. Its core commitment was to classify material remains into distinct cultural groups and trace their movements and interactions through time. For maritime sites, this meant focusing on shipwrecks as containers of artifacts that could be sorted by typology—ceramic styles, coin types, hull construction techniques—and mapped onto known historical cultures. The 1960 excavation of the Cape Gelidonya wreck off Turkey, for example, was interpreted through a culture-historical lens: its cargo of copper ingots and pottery was classified as Late Bronze Age Canaanite, and the wreck was used to document trade routes and cultural contacts in the eastern Mediterranean. The framework's strength was its ability to bring order to scattered underwater finds, creating the first systematic typologies of shipwreck assemblages. Its limitation was that it treated cultures as bounded, static entities and offered little explanation for why maritime practices changed or how people on board experienced their voyages. The methods of classification and typology that Culture-Historical Archaeology developed remain essential in fieldwork today, even though the framework's theoretical assumptions have been largely superseded.
By the 1960s, a new framework—Processual Archaeology—emerged in reaction to the descriptive, particularist approach of culture-historical work. Processualists argued that archaeology should be a science: it should formulate hypotheses about human behavior, test them against material evidence, and seek general explanations for cultural change. For maritime archaeology, this shift meant asking functional and adaptive questions. Why did ship designs change over time? How did maritime trade systems operate as integrated networks? What environmental pressures shaped coastal settlement patterns? The Cape Gelidonya wreck was reinterpreted not just as a Canaanite ship but as evidence for a decentralized, entrepreneurial trading system—a hypothesis that could be tested against the distribution of similar cargoes across the Mediterranean. Processualists introduced quantitative methods, systems thinking, and a focus on technology as a driver of cultural evolution. They also pioneered underwater survey techniques designed to sample sites systematically rather than simply recover spectacular artifacts. The framework's insistence on scientific rigor transformed maritime archaeology into a more rigorous discipline, but its critics charged that it reduced human action to mechanical responses to environment and technology, ignoring meaning, agency, and power.
Beginning in the 1980s, Postprocessual Archaeology launched a sustained critique of processualism's scientific reductionism. Postprocessualists argued that material culture is not a passive reflection of behavior but an active medium through which people create identities, negotiate power, and contest meanings. For maritime archaeology, this opened new lines of inquiry. Shipwrecks were no longer just economic or technological systems; they were sites of human drama—places where sailors, passengers, and slaves experienced fear, solidarity, hierarchy, and resistance. The Cape Gelidonya wreck, from a postprocessual perspective, became a story about the people on board: their social relationships, their daily practices, and the meanings they attached to the cargo they carried. Postprocessualists also emphasized that archaeological interpretations are themselves situated in the present, shaped by the archaeologist's own cultural and political commitments. This reflexive turn encouraged maritime archaeologists to consider how their own assumptions—about progress, technology, or the primacy of Western seafaring—influenced their readings of the past. The framework did not replace processual methods wholesale; many postprocessualists continued to use scientific techniques but insisted that data must be interpreted within a framework that takes human agency and meaning seriously.
Feminist Archaeology emerged in the 1990s as a distinct framework that challenged the gender-blindness of earlier approaches. Maritime archaeology had long assumed that seafaring was an exclusively male domain, and that women's roles were confined to shore-based domestic activities. Feminist archaeologists questioned this assumption by asking new questions: Where are women in the maritime record? How did gender shape labor divisions on ships and in port communities? What evidence might be overlooked if we only look for male-associated artifacts? Studies of shipwreck crews began to examine the presence of women as passengers, cooks, nurses, and even sailors disguised as men. Harbor-side settlements were reanalyzed to reveal women's economic contributions—as traders, innkeepers, and producers of goods for maritime exchange. Feminist Archaeology also critiqued the androcentric language and metaphors that pervaded maritime archaeology, such as the framing of ships as "she" or the romanticization of male explorers. The framework overlaps significantly with Postprocessual Archaeology in its attention to identity and power, but it brings a specific focus on gender as a structuring principle of maritime life. It remains an active and evolving tradition, increasingly intersecting with studies of sexuality, masculinity, and non-binary identities in maritime contexts.
Postcolonial Archaeology, also emerging in the 1990s, addressed a different blind spot: the legacy of colonialism in maritime archaeological practice and interpretation. Much of the subfield had developed around European shipwrecks and colonial trade routes, implicitly centering European agency and treating indigenous peoples as passive recipients of contact. Postcolonial archaeologists argued that this narrative erased the active roles of non-European peoples in maritime history—as navigators, traders, shipbuilders, and resisters. They called for attention to indigenous maritime technologies, such as Polynesian voyaging canoes or Southeast Asian junk rigs, which had been marginalized in a field dominated by European ship typologies. Colonial-era shipwrecks were reinterpreted as sites of encounter, conflict, and cultural negotiation rather than simple evidence of European expansion. The framework also raised questions about heritage ownership: who has the right to excavate and display submerged cultural heritage, especially when it involves the ancestors of colonized peoples? Postcolonial Archaeology shares with Feminist Archaeology a concern for marginalized voices and with Postprocessual Archaeology a critique of universalizing narratives. Its influence has grown as maritime archaeologists increasingly work with descendant communities and indigenous groups to define research priorities and interpret findings.
Today, maritime archaeology is a pluralistic field in which multiple frameworks coexist and interact. Postprocessual, Feminist, and Postcolonial approaches are the most active in shaping new research, while Processual methods remain widely used for data collection and analysis. The leading frameworks agree on several points: that interpretation is never neutral, that power relations shape both the past and the present study of it, and that maritime sites must be understood in their social and political contexts. They disagree, however, on how far to push these commitments. Some argue that scientific data—dendrochronology, isotopic analysis, 3D modeling—can be integrated with interpretive frameworks without contradiction, producing richer accounts of past maritime lives. Others contend that the very categories of "science" and "objectivity" are products of the same Western colonial tradition that the field is trying to move beyond, and that interpretive frameworks must remain primary. A related tension concerns the role of heritage management: should maritime archaeology prioritize academic questions or the needs and desires of descendant communities? These debates are not signs of weakness but of a healthy, self-critical discipline. The frameworks that emerged over the past century have given maritime archaeologists a rich toolkit for asking different kinds of questions, and the field's future lies in the creative, critical use of that toolkit.
