The Copper Age settlements and cemeteries of southeastern Europe, extending from the northern Balkan Peninsula to the northeast across Romania and western Ukraine to the Dnieper, have long been recognized as exceptionally rich and significant. The history of the research on Chalcolithic sites found throughout this interconnected area extends back into the late nineteenth century when scholars first began to excavate the upper levels of what were recognized as settlement mounds with thick cultural deposits (for summary accounts of the histories of research cf. Todorova 1978: 3–6; 1995: 79–82; Fol and Lichardus 1988: 19–26; Monah and Monah 1997: 21–34; Arkheologiya Ukrainskoi SSR 1985: 189–193).

State-funded archaeological research led to an enormous compilation of archaeological materials, a record which for sixth- and fifth-millennia times is arguably as, or more, complete than any other area of the world. Numerous artificially raised settlement hills, tepes and tells of the Near Eastern type, are distributed throughout Bulgaria and southern Romania (Figs. 2.1–2.3).
