The area of the present municipality of Hajdina was settled during all archaeological periods.
Stone tools from the Early Stone Age belong to the oldest findings, and settlements are from the Copper Age. The settlements continued to the Bronze Age and their graves bear witness to the Urnfield culture. Graveyards and tumuli are also from the Iron Age, from Hallstatt (8th – 6th centuries BC). In addition, there is a settlement with the graveyard dating back to the Early Iron Age.
Around 15 BC the Romans arrived to the region and built a military camp of Legio VIII Augustae along the Amber road. In 69 AD the area is mentioned by the Roman historian Tacit in connection with the election of Vespasian to emperor. The camp had a water supply system built by the Legio XIII Gemina. The urban suburbs of Poetovio, namely in the business-religious residential area vicus Fortunae, were the headquarters of Illyrian customs and temples, among which the most well known are Mithras temples I and II, and the temple of Nutrices. The early-Christian church was led by the bishop Victorin of Ptuj at the end of the 3rd century. Roman graves were aligned on both sides of the actual road leading to the village of Pragersko.
A graveyard established in the early Middle Ages was still in use in the 10th century.
