Sudan lies at the crossroads of Africa and the Middle East. It has played a key role in human demographic movements, reflected in the diversity of its cultures and languages. Although much of the country is arid, the Nile River has long acted as a corridor for trade, facilitating human migration through the region for thousands of years.
This makes Sudan a valuable place to study human genetic diversity and evolutionary history, which has important implications for understanding population-specific adaptation and health.
The Copts are a population that migrated from Egypt from the 7th century and mixed with populations in neighbouring regions, but also remained somewhat isolated. Copts are historically distinguished by their Christian faith and their language. In Sudan their numbers are estimated to be in the hundreds of thousands.
