Seima

Seima is a term with several notable uses in archaeology, geography and personal names.

The Seima-Turbino phenomenon refers to an archaeological horizon of the late third to early second millennium BCE characterized by distinctive bronze weaponry and ornaments and a wide, rapid distribution of similar artifact types across Eurasia. First identified from burial finds in the western Siberian and Ural regions, Seima-Turbino‑style objects have been documented from the Urals and West Siberia through Central Asia to parts of East Asia and Eastern Europe. The assemblage is often interpreted as evidence of mobile metalworking groups or long-distance exchange networks that contributed to the spread of metallurgical technology and new weapon forms in the Bronze Age.

Seima Protected Forest is a conservation area in eastern Cambodia noted for relatively intact lowland evergreen and semi-evergreen forest, wetlands and riverine habitats. It supports globally threatened species, including Asian elephant, large ungulates and several primates, and is the subject of national and international conservation efforts to balance biodiversity protection with local livelihoods.

Seima is also used as a given name or surname in various cultures. As a toponym and term in scholarship, its meaning depends on context, and discussions typically specify whether they refer to the archaeological phenomenon, the Cambodian protected forest, or personal name usage.
