Prehistory and protohistory of Poland

Stone Age

Poland's Stone Age is divided into the Paleolithic, Mesolithic and Neolithic eras.

The Paleolithic era extended from c. 500,000 BC to 8,000 BC and is subdivided into four periods: the Lower Paleolithic, c. 500,000 to 350,000 BC; the Middle Paleolithic, c. 350,000 to 40,000 BC; the Upper Paleolithic, c. 40,000 to 10,000 BC; and the Final Paleolithic, c. 10,000 to 8000 BC.

The Mesolithic era lasted from c. 8000 to 5500 BC and the Neolithic from c. 5500 to 2300 BC.

The Neolithic is subdivided into the Neolithic proper, c. 5500 – 2900 BC, and the Copper Age, c. 2900 – 2300 BC.

Poland's Stone Age lasted approximately 500,000 years and saw the appearance of three distinct Homo species: Homo erectus, Homo neanderthalensis and Homo sapiens (humans). The Stone Age cultures ranged from early human groups with primitive tools to advanced agricultural and stratified societies that used sophisticated stone tools, built fortified settlements and developed copper metallurgy.

As elsewhere in Central Europe, the Paleolithic, Mesolithic and Neolithic stages of Poland's Stone Age were each characterized by refinements in stone-tool-making techniques. Paleolithic human activities (whose earliest sites are 500,000 years old) were intermittent because of recurring glaciations. A general climate warming and a resulting increase in ecologic diversity were characteristic of the Mesolithic era (9000–8000 BC).

The Neolithic era ushered in the first settled agricultural communities, whose founders had migrated from the Danube River area beginning about 5500 BC. Later, the native post-Mesolithic populations would also adopt and further develop the agricultural way of life (between 4400 and about 2000 BC).

Bronze and Iron Ages

Poland's Bronze Age comprised Period I, c. 2300–1600 BC; Period II, c. 1600–1350 BC; Period III, c. 1350–1100 BC; Period IV, c. 1100–900 BC; and Period V, c. 900–700 BC. The Early Iron Age included Hallstatt Period C, c. 700–600 BC, and Hallstatt Period D, c. 600–450 BC.

Poland's Bronze- and Iron-Age cultures are known mainly from archeological research. Poland's Early Bronze Age cultures began around 2300-2400 BC, whereas the Iron Age commenced c. 700-750 BC. By the beginning of the Common Era, the Iron Age archeological cultures described in the main article no longer existed. Given the absence of written records, the ethnicities and linguistic affiliations of the groups living in Central and Eastern Europe at that time are speculative; there is considerable disagreement about their identities. In Poland, the Lusatian culture, which spanned the Bronze and Iron Ages, became particularly prominent. The most famous archeological discovery from that period is the Biskupin fortified settlement (gród) that represented early-Iron-Age Lusatian culture.

Bronze objects were brought to Poland around 2300 BC from the Carpathian Basin. The native Early Bronze Age that followed was dominated by the innovative Unetice culture in western Poland and the conservative Mierzanowice culture in eastern Poland. These were replaced in their respective territories for the duration of the subsequent Older Bronze Period by the (pre-Lusatian) Tumulus culture and the Trzciniec culture.

Characteristic of the remaining bronze periods were the Urnfield cultures, in which skeletal burials were replaced by cremation throughout much of Europe. In Poland, the Lusatian culture settlements dominated the landscape for nearly a thousand years, continuing into the Early Iron Age. A series of Scythian invasions beginning in the 6th century BC, precipitated their demise. The Hallstatt Period D was a time of expansion for the Pomeranian culture, while the Western Baltic Kurgan culture dominated Poland's Masuria-Warmia region.

Antiquity

The period of the La Tène culture is subdivided into La Tène A, c. 450–400 BC; La Tène B, c. 400–250 BC; La Tène C, c. 250–150 BC; and La Tène D, c. 150–0 BC. The period from 200 to 0 BC may also be considered a younger pre-Roman period. It was followed by a period of Roman influence whose early stage lasted from c. 0 to 150 AD and its later stage from c. 150 to 375 AD. The period from 375 to 500 AD constitutes the (pre-Slavic) Migration Period.

Peoples belonging to numerous archeological cultures identified with Celtic, Germanic, Baltic, and in some regions Slavic tribes inhabited parts of Poland during the era of classical antiquity, from about 400 BC to 450-500 AD. Other groups, difficult to identify, were most likely also present, as the ethnic composition of archeological cultures is often poorly recognized. Short of using a written language to any appreciable degree, many of them developed a relatively advanced material culture and social organization, as evidenced by the archeological record, for example by richly furnished, dynastic "princely" graves. Characteristic of this period were high rates of migration, often involving large groups of people.

Celtic peoples established settlements beginning in the early 4th century BC, mostly in southern Poland, the outer limit of their expansion, as representatives of the La Tène culture. With their developed economy and crafts, they exerted a lasting cultural influence disproportionate to their small numbers in the region.

Germanic peoples lived in what is now Poland for several centuries, during which many of their tribes also migrated southward and eastward (see Wielbark culture). With the expansion of the Roman Empire, the Germanic tribes came under Roman cultural influence. Some written remarks by Roman authors that are relevant to developments on Polish lands have been preserved; they provide additional insights in conjunction with the archeological record. In the end, as the Roman Empire was nearing its collapse and the nomadic peoples invading from the east destroyed, damaged or destabilized the various Germanic cultures and societies, the Germanic peoples left Eastern and Central Europe for the safer and wealthier southern and western parts of the European continent. According to Tacitus and Ptolemy, the Goths left the lower Vistula region in the mid-2nd century AD.

The northeast corner of what is now Poland remained populated by Baltic tribes. They were at the outer limits of any substantial cultural influence from the Roman Empire.

Slavic peoples may have lived in the southern and southeastern regions, some perhaps associated with the ancient Przeworsk and Zarubintsy cultures of the 3rd century BC (with the Przeworsk culture being considered likely of Slavic or of mixed Slavic and Germanic origin). It has been suggested that the early Slavic peoples and languages may have originated in the region of Polesia, which includes the area around the Belarus–Ukraine border, parts of Western Russia, and parts of far Eastern Poland. More of Poland would be settled by Slavic tribes in later periods, in the early centuries of the common era.
