The end of the Bronze Age saw extensive movements of tribes, known as the "Great Aegean Migration". This caused the dislocation of populations over an extensive territory. The uncertain times aroused fear in the native populations, and as a result some people buried their valuables in the so-called "hoards", hoping that one day, when circumstances became more secure, they would dig them out. Many owners never came back for them.
The hoard found at Autokomanda in Belgrade contained 19 objects, mostly bracelets, covered with pale green patina, but well preserved and decorated with particularly rich geometric ornaments. The hoard shows that some decorative elements, which are associated with Central Europe, originated in this region as a result of the advanced development of mining and the art of casting.
