5th millennium BC in the context of "Copper Age"

The Chalcolithic (/ˈkælkəˌlɪθɪk/ KAL-kə-LI-thik) (also called the Copper Age and Eneolithic) was an archaeological period characterized by the increasing use of smelted copper. It followed the Neolithic and preceded the Bronze Age. It occurred at different periods in different areas, but was absent in some parts of the world, such as Russia, where there was no well-defined Copper Age between the Stone and Bronze Ages. Stone tools were still predominantly used during this period.

The Chalcolithic covers both the early cold working (hammering) of near pure copper ores, as exhibited by the likes of North American Great Lakes Old Copper complex, from around 6,500 BC, through the later copper smelting cultures. The archaeological site of Belovode, on Rudnik mountain in Serbia, has the world's oldest securely dated evidence of copper smelting at high temperature, from c. 5,000 BC. The transition from Copper Age to Bronze Age in Europe occurred between the late 5th and the late 3rd millennium BC. In the Ancient Near East the Copper Age covered about the same period, beginning in the late 5th millennium BC and lasting for about a millennium before it gave rise to the Early Bronze Age.

The Chalcolithic or Copper Age is the transitional period between the Neolithic and the Bronze Age. It is taken to begin around the mid-5th millennium BC, and ends with the beginning of the Bronze Age proper, in the late 4th to 3rd millennium BC, depending on the region.

The Chalcolithic is part of prehistory, but based on archaeological evidence, the emergence of the first state societies can be inferred, notably in the Fertile Crescent (notably Sumer) Predynastic Egypt, and Proto-Minoan Crete, with late Neolithic societies of comparable complexity emerging in the Indus Valley (Mehrgarh), China, and along the north-western shores of the Black Sea.

Adams Synchronological Chart or Map of History, originally published as Chronological Chart of Ancient, Modern and Biblical History is a wallchart which graphically depicts a Biblical genealogy alongside a timeline composed of historic sources from the history of humanity from 4004 BC to modern times.

Published in 1871 by writer, educator, and Presbyterian minister Sebastian C. Adams, the chart integrates genealogies of the King James Bible with numerous historical references and compendiums (listed in the Sources, below)* merging secular history with a chronological account beginning with Adam and Eve in 4004 B.C.

In archaeogenetics, the term Western Steppe Herders (WSH), or Western Steppe Pastoralists, is the name given to a distinct ancestral component first identified in individuals from the Chalcolithic steppe around the start of the 5th millennium BC, subsequently detected in several genetically similar or directly related ancient populations including the Khvalynsk, Repin, Sredny Stog, and Yamnaya cultures, and found in substantial levels in contemporary populations of Europe, Central Asia, South Asia and West Asia. This ancestry is often referred to as Yamnaya ancestry, Yamnaya-related ancestry, Steppe ancestry or Steppe-related ancestry.

Western Steppe Herders are considered to be descended from a merger between Eastern Hunter-Gatherers (EHGs) and Caucasus Hunter-Gatherers (CHGs). The WSH component is modeled as an admixture of EHG and CHG ancestral components in roughly equal proportions, with the majority of the Y-DNA haplogroup contribution from EHG males. The Y-DNA haplogroups of Western Steppe Herder males are not uniform, with the Yamnaya culture individuals mainly belonging to R1b-Z2103 with a minority of I2a2, the earlier Khvalynsk culture also with mainly R1b but also some R1a, Q1a, J, and I2a2, and the later, high WSH ancestry Corded Ware culture individuals mainly belonging to haplogroup R1b in the earliest samples, with R1a-M417 becoming predominant over time.

Banwari Trace, an Archaic (pre-ceramic) site in southwestern Trinidad, is the oldest archaeological site in the Caribbean. The site has revealed two separate periods of occupation; one between 7200 and 6100 BP (Strata I and II) and the other between 6100 BP and 5500 BP.

The Cucuteni–Trypillia culture, also known as the Cucuteni culture or Trypillia culture is a Neolithic–Chalcolithic archaeological culture (c. 5050 to 2950 BC) of Southeast Europe. It extended from the Carpathian Mountains to the Dniester and Dnieper regions, centered on modern-day Moldova and covering substantial parts of western Ukraine and northeastern Romania, encompassing an area of 350,000 km (140,000 sq mi), with a diameter of 500 km (300 mi; roughly from Kyiv in the northeast to Brașov in the southwest).

The majority of Cucuteni–Trypillia settlements were of small size, high density (spaced 3 to 4 kilometres apart), concentrated mainly in the Siret, Prut and Dniester river valleys. During its middle phase (c. 4100 to 3500 BC), populations belonging to the Cucuteni–Trypillia culture built some of the largest settlements in Eurasia, some of which contained as many as three thousand structures and were possibly inhabited by 20,000 to 46,000 people. The 'mega-sites' of the culture, which have been claimed to be early forms of cities, were the largest settlements in Eurasia, and possibly the world, dating to the 5th millennium BC. The population of the culture at its peak may have reached or exceeded one million people. The culture was wealthy and influential in Eneolithic Europe and the late Trypillia culture has been described by scholar Asko Parpola as thriving and populous during the Copper Age. It has been proposed that it was initially egalitarian and that the rise of inequality contributed to its downfall.

The history of Bulgaria can be traced from the first settlements on the lands of modern Bulgaria to its formation as a nation-state, and includes the history of the Bulgarian people and their origin. The earliest evidence of hominid occupation discovered in what is today Bulgaria date from at least 1.4 million years ago. Around 5000 BC, a sophisticated civilization already existed which produced some of the first pottery, jewellery and golden artifacts in the world. After 3500 BC, the Thracians appeared on the Balkan Peninsula. In the late 6th century BC, parts of what is currently Bulgaria, in particular the eastern region of the country, came under the Persian Achaemenid Empire. In the 470s BC, the Thracians formed the powerful Odrysian Kingdom which lasted until 46 BC, when it was finally conquered by the Roman Empire. During the centuries, some Thracian tribes fell under ancient Macedonian and Hellenistic, and also Celtic domination. This mixture of ancient peoples was assimilated by the Slavs, who permanently settled on the peninsula after 500 AD.
