  The first Stone Age archaic humans and Homo erectus species settled what was to become Poland approximately 500,000 years ago, though the ensuing hostile climate prevented early humans from founding more permanent encampments. The arrival of Homo sapiens and anatomically modern humans coincided with the climatic discontinuity at the end of the Last Glacial Period (Northern Polish glaciation 10,000 BC), when Poland became habitable. Neolithic excavations indicated broad-ranging development in that era; the earliest evidence of European cheesemaking (5500 BC) was discovered in Polish Kuyavia, and the Bronocice pot is incised with the earliest known depiction of what may be a wheeled vehicle (3400 BC).
  
  The period spanning the Bronze Age and the Early Iron Age (1300 BC–500 BC) was marked by an increase in population density, establishment of palisaded settlements (gords) and the expansion of Lusatian culture. A significant archaeological find from the protohistory of Poland is a fortified settlement at Biskupin, attributed to the Lusatian culture of the Late Bronze Age (mid-8th century BC).
  
  Throughout antiquity (400 BC–500 AD), many distinct ancient populations inhabited the territory of present-day Poland, notably Celtic, Scythian, Germanic, Sarmatian, Baltic and Slavic tribes. Furthermore, archaeological findings confirmed the presence of Roman Legions sent to protect the amber trade. The Polish tribes emerged following the second wave of the Migration Period around the 6th century AD; they were Slavic and may have included assimilated remnants of peoples that earlier dwelled in the area. Beginning in the early 10th century, the Polans would come to dominate other Lechitic tribes in the region, initially forming a tribal federation and later a centralised monarchical state.
