towns, most notably Karina, in Bombali District in the north; Kabala and Falaba in Koinadugu District in the north; and Yengema, Kono District in the east of the country. Like the Fula, the Mandinka are virtually all Muslims at over 99℅. Sierra Leone's third president, Ahmad Tejan Kabbah, and Sierra Leone's first Vice-President, Sorie Ibrahim Koroma, were both ethnic Mandingo. Next in proportion are the Kono, who live primarily in Kono District in Eastern Sierra Leone. The Kono are descendants of migrants from Guinea; today their workers are known primarily as diamond miners. The majority of the Kono ethnic group are Christians, though with an influential Muslim minority. Sierra Leone's former Vice-President Alhaji Samuel Sam-Sumana is an ethnic Kono. The small but significant Creole or Krio people (descendants of freed African American, West Indian and Liberated African slaves who settled in Freetown between 1787 and about 1885) make up about 3% of the population. They primarily occupy the capital city of Freetown and its surrounding Western Area. Creole or Krio culture reflects the Western culture and ideals within which many of their ancestors originated – they also had close ties with British officials and colonial administration during years of development. The Creoles or Krio have traditionally dominated Sierra Leone's judiciary and Freetown's elected city council. One of the first ethnic groups to become educated according to Western traditions, they have traditionally been appointed to positions in the civil service, beginning during the colonial years. They continue to be influential in the civil service. The Creoles or Krios are virtually all Christians at about 99%. The Oku people are the descendants of liberated muslim Yorubas from Southwest Nigeria, who were released from slave ships and resettled in Sierra Leone as Liberated Africans or came as settlers in the mid-19th century. The Oku people primarily reside in the communities of Fourah Bay, Fula Town, and Aberdeen in Freetown. The Oku are virtually all Muslims at about 99%. Other minority ethnic groups are the Kuranko, who are related to the Mandingo and are largely Muslims. The Kuranko are believed to have begun arriving in Sierra Leone from Guinea in about 1600 and settled in the north, particularly in Koinadugu District. The Kuranko are primarily farmers; leaders among them have traditionally held several senior positions in the Military. The current Governor of the Bank of Sierra Leone Kaifala Marah is an ethnic Kuranko. The
