In the fourth episode, Zeinab Badawi travels to the country of her birth and the very region of her forefathers: northern Sudan. Here, she examines a little known aspect of ancient African history: the Kingdom of Kush. Zeinab explains how, in the eighth century BC, Kush conquered and governed in Egypt for the best part of 100 years, becoming a regional superpower with their influence extending to the modern day Middle East. Zeinab also visits some of the best preserved of Sudan's 1,000 pyramids and uncovers how the customs of Kush are still maintained to this day. Show less
