The ancient world was more connected than popular imagination suggests. By 2000 BCE, copper mined in Oman was traded in Mesopotamia; tin from Afghanistan was alloyed with Cypriot copper in Mediterranean workshops; Baltic amber decorated Egyptian tombs; lapis lazuli from Afghanistan adorned Mesopotamian temples. The Bronze Age world was, in a meaningful sense, a global economy.
The term may seem anachronistic, but the Bronze Age world supported genuine long-distance trade in bulk commodities — copper, tin, grain, textiles — across distances of thousands of miles. The Uluburun shipwreck's cargo came from at least seven different cultural regions. The Old Assyrian trading colonies in Anatolia connected Mesopotamia commercially with Anatolia in networks documented by 23,000 surviving clay tablets from Kanesh. These were not occasional exotic exchanges but sustained commercial relationships with institutional infrastructure.

The famous Silk Road — actually a network of overland and maritime routes — formally connected China with the Mediterranean from the 2nd century BCE onward. But earlier networks preceded it. Afghan lapis lazuli reached Egypt by 3000 BCE, requiring overland routes through Iran and Iraq. Tin from the Erzgebirge mountains of central Europe appeared in Bronze Age Mediterranean bronzes. The routes that would later carry silk were already carrying copper, tin, and amber centuries before Chinese silk entered the picture.
Baltic amber — fossil tree resin prized for its beauty — appears in Mediterranean archaeological sites from at least 3000 BCE, thousands of miles from its northern source. The amber routes that carried it southward through Europe overlapped with copper and tin distribution networks, creating a complex European trade infrastructure that connected the Baltic coast with Mediterranean civilisations. The same routes brought Mediterranean bronze goods north and Baltic amber south — a genuinely global exchange for its era.
Yes. By 2000 BCE, goods were routinely moving thousands of miles along established trade networks — copper from Oman to Mesopotamia, amber from the Baltic to Egypt, lapis lazuli from Afghanistan to Mediterranean cities.
Copper (and tin for bronze production) — because they were essential for tools and weapons, relatively rare, and geographically concentrated, making long-distance trade economically necessary.
