 Proto-Shona speaking societies first emerged in the middle Limpopo valley in the 9th century before moving on to the Zimbabwean highlands. The Zimbabwean plateau eventually became the centre of subsequent Shona states, beginning around the 10th century. Around the early 10th century, trade developed with Arab merchants on the Indian Ocean coast, helping to develop the Kingdom of Mapungubwe in the 11th century. This was the precursor to the more impressive Shona civilisations that would dominate the region during the 13th to 15th centuries, evidenced by ruins at Great Zimbabwe, near Masvingo, and other smaller sites. The main archaeological site uses a unique dry stone architecture.
