The Chernyakhov culture, or Sântana de Mureș culture, is an archaeological culture that flourished between the 2nd and 5th centuries AD in a wide area of Eastern Europe, specifically in what is now Ukraine, Romania, Moldova and parts of Belarus. The culture is probably the result of a multiethnic cultural mix of the Sarmatian, Slavic, Gothic, and Geto-Dacian (including Romanised Daco-Romans) populations of the area.
The Chernyakhov culture territorially replaced its predecessor, the Zarubintsy culture. In Ukraine both cultures were discovered by the Austrian-Russian archaeologist, Vikentiy Khvoyka, who conducted numerous excavations around Kyiv and its vicinity. Among other archaeologists are Austrian Karel Hadáček from Eastern Galicia and Ivan Kovac from Transylvania. With the invasion of Huns, the culture declined and was replaced with the Penkovka culture (or the culture of the Antes).
The Chernyakhov culture is very similar to the Wielbark culture, which was located closer to the Baltic Sea.
The Chernyakhov culture encompassed regions of modern Ukraine, Moldova, and Romania. It is named after the localities Sântana de Mureș, Mureș County, Transylvania in Romania and Cherniakhiv, Kaharlyk Raion, Kyiv Oblast in Ukraine. The dual name reflects past preferential use by different schools of history (Romanian and Soviet) to designate the culture.
