Two Americans, Viola Fletcher and Van Ellis have accepted offers to become Ghanaian citizens.

They said they accepted the offer because Ghana “represents Africa.”

“We accept it with great joy, and we thank the president for this great honour,” BBC quoted the centenarians as having said during their tour of Ghana.

Ms Fletcher, 107, and Mr Ellis, 100, were survivors of the 1921 massacre of black people in Tulsa, a city in the U.S.

They had visited Ghana to mark the centenary of the Tulsa Race Massacre, which saw hundreds of black people murdered and properties and businesses belonging to blacks destroyed during the massacre.

The duo, who has been in the African country since last weekend for a tour of Africa, visited historic sites such as the Osu Castle Dungeon, where they decried the horrors of slavery.

The centenarians called for African unity, just as they also laid a wreath at the tomb of the Pan-African human rights activist W.E.B. Du Bois.

During their visit to the Nigerian Igbo community in Ghana, the duo who also paid a courtesy call to President Nana Akufo-Addo, were crowned honorary chief and queen mother.
