The Požega Valley is surrounded by Psunj, Papuk, Krndija in the North, Požeška Gora and Dilj in the South and represents a specific geographical unity. During the late Pleiostocene epoch or the Third Stadial ( 110 000 till 11 500 B.C.), there existed a steppe landscape with a rather cold climate. From that time several skeletal rests of extinct animals have been found- Mammuthus primigenius, Bison priscus, Megaceros gigantens, Ursus Spaeleous, Hyaena Spaeleous (these animals are typical for the open steppe landscape). These remains were found around Zarilac – Grabaračke livade hint at the existance of Paleolitic hunters' camp.
The locality of Zarilac – Grabaračke livade were inhabited in the later periods. During the Early Stone Age/Neolithic (6 000- 5 000 B.C.) the strong continental climate becomes smooth. As a conclusion, the region has an increased downfall and a marshland has been resulted in the lower regions. According to the fertile soil and the thick forest the Požega Valley has shown a dense population throughout all historical periods. The economy, which was based on agriculture, caused that the population settled down and developed permanent living.
The representative of the Early and Mittle Neolithic Era is the Starčevo Culture (6 000 B.C.) and was spread between the Drave, Danube and Sava all the way to Bjelovar in the West. Pottery pots are the most found rests of material culture. Besides chipped stone items, axes and pins are the most common stone items.
The representative of the Early Neolithic (Eneolithic) Era is the Sopot Culture (5 000 B.C.). It was named after Sopot, a site located 3 km southwest of Vinkovci. The members of the Sopot culture built their houses on hills near banks of rivers, streams and in marshlands. Their houses had the base of rectangular shape (6x4m), constructed of boughs with loam. Apart from smooth polished surfaces of simple pottery axes with drilled holes for handles appear for the first time among stone tools.
On the basis of the Late Sopot culture the first Eneolithic culture developed. The main characteristic of the Copper Age or the Eneolithic (aeneus-copper, bronze, lithos-stone) is the use of metals, such as copper and gold, to make jewellery, weapons and tools. The Copper Age cultures (4 000- 3 000 B.C.) had agricultural and partly nomadic, cattle breeding characteristics. In the region of the valley around Požega the Lasinja culture was present, as well. It can approximatelly be dated back to the period between 4 200 and 3 800 B.C., and in Jakšić there have been made the most significant findings of this culture – five pottery pots. These pots show the basic characteristics of pottery manufacture in the Lasinja culture. Biconical bowls, pots with prolonged necks, jugs and cups with one band-like handle, and special bowls on a high leg, were predominant in the Lasinja culture when it comes to pottery shapes. Common decorations were large, tongue-shaped plastic protrusions on bowls, and a mixture of engraved motifs and a series of stabs or short incisions creating a shape of fish-bone pattern, barbed wire, garlands or simple parallel lines.
