Analyze archaeological evidence from Great Zimbabwe to explain its trade connections and its history as evidence of African achievement.
In southeastern Africa, between about 1100 and 1450 CE, the Shona people built a stone city so large and impressive that its name -- Zimbabwe, from a Shona phrase meaning "stone houses" -- eventually gave the modern nation its name. Great Zimbabwe's most famous structure, the Great Enclosure, has walls up to 36 feet high built from carefully cut granite blocks stacked WITHOUT any mortar to hold them together -- a technique requiring precise skill, since the stones had to fit tightly enough to support their own weight for centuries.
Archaeologists have found objects at Great Zimbabwe that did not come from anywhere nearby: Chinese porcelain, Persian pottery, and glass beads from as far away as India, all likely arriving through Indian Ocean trade with coastal cities. That evidence shows Great Zimbabwe was linked to a trade network stretching across the Indian Ocean, probably trading gold, ivory, and cattle for these imported goods. For decades under colonial rule in the early 1900s, some European officials and writers wrongly insisted that Africans could not have built something so sophisticated, and credited outsiders instead -- despite the evidence. Careful archaeology, including an excavation by Gertrude Caton-Thompson in 1929, confirmed what the evidence had shown all along: Great Zimbabwe was built by the ancestors of the Shona people. This history is itself an example of why examining evidence honestly, instead of assuming what you expect to find, matters so much.
Mastery looks like: They can explain how imported artifacts at Great Zimbabwe prove Indian Ocean trade connections, and describe how archaeology corrected a false colonial-era claim.
Common stumbles: Assuming the imported artifacts were made locally, or missing why the colonial-era denial of African builders is historically significant, not just a side note.
