University of Minnesota Messenia Expedition
The University of Minnesota Messenia Expedition (UMME) was an archaeological project in Messenia, Greece, that ran from 1953 to 1975. It was started by William McDonald, who directed most of the work, and grew out of the discovery that the Linear B tablets found at Pylos described a Mycenaean political system that controlled a wide area. McDonald and, later, Richard Hope Simpson began large-scale surveys to match the place names in those tablets to real sites in Messenia. Over the 1950s and 1960s they mapped about 3,800 square kilometres and collected evidence of habitation from the Neolithic to the Medieval periods. The project helped make Messenia one of the best-studied regions of Mycenaean Greece and inspired many later Greek archaeological projects.
The UMMME was notable for its collaborative and broad approach. It brought together specialists from different fields—geologists, botanists, archaeologists—and emphasized studying how the landscape and modern human geography related to ancient settlement. Early work focused on identifying sites from Classical authors and cross-checking place names with the modern topography, with a goal of finding settlements contemporary with the Linear B tablets from Pylos. The team worked with local authorities and used a regional survey method rather than focusing only on excavated centers. They aimed to learn about Mycenaean life across a long span, especially the LH IIIB period (roughly 1300–1180 BCE), which coincided with the fall of the Nestor’s Palace and the tablet discoveries.
From 1961 onward, the expedition’s name, UMME, was used officially. McDonald and Simpson were joined by several Minnesota faculty members and increased funding from foundations. Their methods included large-scale “regional exploration,” sometimes using a Land Rover to drive through the countryside, and a preference for finding sites through surface finds rather than deep excavation. They also used aerial photography to spot features from above, with the Royal Hellenic Air Force providing the images. The combination of survey, aerial data, and interdisciplinary analysis led to a large increase in known sites: around 215 prehistoric sites and 98 later-inhabited locations were documented.
The expedition’s second major phase was the excavation of Nichoria, a site in southern Messenia that had Mycenaean and Early Iron Age remains. From 1969 to 1973 (with processing through 1975), Nichoria yielded important evidence about the end of the Bronze Age and the transition to the Iron Age. The dig, conducted under permit from the American School of Classical Studies at Athens, revealed a settlement and cemeteries covering about five hectares. It included a tholos tomb (now known as the UMME or MME tholos) and material spanning from the Early Helladic through the Early Iron Age. The team used new scientific methods—magnetometry to map the site, photogrammetry for mapping, and both dry and wet sieving to recover tiny artifacts and plant and animal remains. They also began to carbon-date some finds, which showed the limitations of that technique in the Aegean. Nichoria’s excavation contributed to understanding the Bronze Age–Iron Age transition and helped demonstrate the value of multidisciplinary, processual archaeology.
The UMMME’s findings had a broad impact. The project documented far more regional variety than previous work and helped establish Messenia as a well-documented region of prehistoric Greece. It influenced later regional surveys in Greece, such as the Pylos Regional Archaeological Project, which built on the UMME’s large-scale landscape data but sought more intensive study of smaller areas. Nichoria, in particular, became a key site for studying diet and economy. Analysis of animal bones suggested that goats were the primary meat source in the Mycenaean period, with cattle becoming more prominent in the Early Iron Age. This pattern sparked debate about changes in food economy and population, and about how to interpret the shift from Bronze to Iron Age society. Some researchers suggested a “pastoral” shift in population patterns, but later work questioned this interpretation, noting biases in bone preservation and dating.
Overall, the Minnesota Messenia Expedition is often described as a turning point in Greek archaeology. It demonstrated the value of large-scale, diachronic landscape surveys and a multidisciplinary approach, helping scholars move from site-by-site digging to understanding how regions functioned over centuries. The work expanded the known inventory of Mycenaean sites outside the great palatial centers and laid the groundwork for future regional studies that would continue to shape our view of Bronze and Iron Age Greece.
