Tanzeela Qambrani, 39, was nominated by the Pakistan People's Party (PPP), of former Prime Minister Benazir Bhutto, to a women's reserved seat in the regional parliament of southern Sindh province.
She hopes her nomination after last month's election will help wash away the stigma attached to the Sidi community, the local name for the ethnic African population concentrated in the coastal regions of Makran and Sindh.
"As a tiny minority lost in the midst of local populations, we have struggled to preserve our African roots and cultural expression, but I look forward to the day when the name Sidi will evoke respect, not contempt," Ms Qambrani, whose ancestors came from Tanzania, told the BBC.
Many Sidis are believed to be descended from slaves brought to India from East Africa by the Portuguese. Historians say their ancestors were also soldiers, traders, pearl divers and Muslim pilgrims.
They enjoyed senior positions during the Mughal empire but faced discrimination under British colonial rule.
Estimates put their population in Pakistan in the tens of thousands. They are well-integrated but keep alive some traditions, including an annual festival that blends Islamic mysticism, crocodiles and singing in a blend of Swahili and a local language called Baluchi.
