They visited a school to talk about mental health and met wounded soldiers in northern Kaduna.
It was their first trip to Africa’s most populous nation, and came amid interest expressed by Nigeria, according to Prince Harry, to host the Invictus Games in 2029.
At an event hosted by Ngozi Okonjo-Iweala, a Nigerian economist and head of the World Trade Organisation, Meghan had said when she learned of her Nigerian ancestry her first response had been to tell her mother.
“Being African American, part of it is really not knowing so much about your lineage and background … and it was exciting for both of us,” she said.
“Never in a million years would I understand it as much as I do now. And what has been echoed so much in the past day is, ‘Oh, we are not so surprised when we found out you are Nigerian’.”
She concluded her remarks to the audience: “It is a compliment to you because what they define as a Nigerian woman is brave, resilient, courageous, beautiful.”
The Duchess did not immediately respond to a request for comment from The Telegraph.
Meghan and Harry moved to the United States in June 2020 after their decision to leave the Royal family amid allegations she felt she had not been sufficiently supported.
