what evidence suggests that great zimbabwe was a center of trade
Great Zimbabwe Archaeological evidence suggests that Great Zimbabwe became a centre for trading, with artefacts suggesting that the city formed part of a trade network linked to Kilwa[25] and extending as far as China. Copper coins found at Kilwa Kisiwani appear to be of the same pure ore found on the Swahili coast.[26] This international trade was mainly in gold and ivory; some estimates indicate that more than 20 million ounces of gold were extracted from the ground.[27] That international commerce was in addition to the local agricultural trade, in which cattle were especially important.[14] The large cattle herd that supplied the city moved seasonally and was managed by the court.[19] Chinese pottery shards, coins from Arabia, glass beads and other non-local items have been excavated at Zimbabwe. Despite these strong international trade links, there is no evidence to suggest exchange of architectural concepts between Great Zimbabwe and centres such as Kilwa.[28]
