The excavations at the Malian city of Gao carried out by Cambridge University revealed glass windows. One of the findings was entitled: “Fragments of alabaster window surrounds and a piece of pink window glass, Gao 10th – 14th century.”
Gao, founded by fishermen in the 7th century, is one of the oldest trading centres in western Africa. Gao became the capital of the Songhai Empire in the early 11th century. https://twitter.com/Joe__Bassey/status/1293074309821411331?s=19
Under Songhai rule the town thrived as a major trans-Saharan trading centre for gold, copper, slaves, and salt. The rulers of the kingdom of Mali annexed Gao in 1325, but the Songhai regained control of it some 40 years later.
The Moroccans ended Songhai rule over Gao in 1591.
