Yékini is the nickname of Yakhya Diop (26 February 1974 in Joal), a popular champion of Senegalese wrestling, the most prominent variant of the Lutte Traditionnelle, a West African folk tradition which has become a major professional sport in the last two decades.
 From the Serer ethnic group, Yékini is the most successful wrestler since the professionalisation of the sport, and his appearances are major news in his home country.
 His 2006 fight against and defeat of Mohamed Ndao, alias Tyson, was billed in Senegal as "the fight of the century", cementing the two as the best known exponents of the sport.
 He was defeated by Balla Gaye 2, The Lion of Guédiawaye, at Stade Demba Diop on Sunday 22 April 2012, ending a reign that spanned almost two decades.
Terence Hill (born Mario Girotti; 29 March 1939) is an Italian actor, film director, screenwriter and film producer.
Enzo Barboni (July 7, 1922 – March 23, 2002), sometimes credited by his pseudonym E.B. Clucher, was an Italian film director, cinematographer and screenwriter, best known for his slapstick comedies starring Terence Hill and Bud Spencer.
Anton Tomaž Linhart (11 December 1756 – 14/15 July 1795) was a Carniolan playwright and historian, best known as the author of the first comedy and theatrical play in general in Slovene, "Županova Micka" (Micka, the Mayor's Daughter).
 He is also considered the father of Slovene historiography, since he was the first historian to write a history of all Slovenes as a unit, rejecting the previous concept which focused on single historical provinces.
 He was the first one to define the Slovenes as a separate ethnic group and set the foundations of the Slovene ethnography.
The Iatmul are a large ethnic group of about 10,000 people inhabiting some two-dozen politically autonomous villages along the middle Sepik River in Papua New Guinea.
 The communities are roughly grouped according to dialect of the Iatmül language as well as sociocultural affinities.
 The Iatmul are best known for their art, men's houses, male initiation, elaborate totemic systems, and a famous ritual called "naven", first studied by Gregory Bateson in the 1930s.
 More recently, the Iatmul are known as a location for tourists and adventure travelers, and a prominent role in the 1988 documentary film "Cannibal Tours".
The Di (; Old Chinese: *tˁij) were an ancient ethnic group that lived in western China, and are best known as one of the non-Han Chinese peoples that overran northern China during the Jin Dynasty (265–420) and the Sixteen Kingdoms period.
 This ethnic group should not be confused with the Dí 狄, which refers to unrelated nomadic peoples in northern China during the earlier Zhou Dynasty.
 The Di are thought to have been of proto-Tibetan origin, though there is a widespread belief among Chinese scholars that the Di have spoken an Altaic (specifically Turkic) language.
Benoît Sinzogan (born July 14, 1930) is a Beninese military officer and politician, best known for leading his country's gendarmerie in the late 1960s.
 He was a member of the Fon ethnic group, which dominated the Beninese (then known as Dahomeyan) army from 1965 to 1967.
 After Maurice Kouandété usurped the presidency on December 17, Sinzogan was placed under house arrest until December 19.
 That day, Sinzogan was appointed Minister of Foreign Affairs, his first political post, which he held until July 1968.
 He was a member of the Military Directorate, which ruled Dahomey from 1969-1970.
 Academic Samuel Decalo described the man as "too timid to mount a coup" during the 1960s and 1970s, being "one of Dahomey's few senior officers not to attempt to."

Sikasso Region is the southern-most region of Mali.
 The region's capital city, Sikasso, is the country's second-largest city and is growing rapidly due to people fleeing the violence in Côte d'Ivoire to the south.
 Major ethnic groups include the Senoufo, known for masks and reverence for animals, the Samago, known for being Mali's best farmers, and the main ethnic group in Mali, the Bambara people.
The local economy is based on farming and the Sikasso, which receives more rain than any other Malian region, is known for its fruits and vegetables.
Ekoi people, also known as Ejagham, are an ethnic group in the extreme southeast of Nigeria and extending eastward into the southwest region of Cameroon.
 They speak the Ekoi language, the main Ekoid language.
 Other Ekoid languages are spoken by related groups, including the Etung, some groups in Ikom (such as Ofutop, Akparabong and Nde), some groups in Ogoja (Ishibori and Bansarra), Ufia and Yakö.
 The Ekoi have lived closely with the nearby Efik, Annang, Ibibio and Igbo people of southeastern Nigeria.
 The Ekoi are best known for their Ekpe headdresses.
 They traditionally use Nsibidi ideograms, and may be the group that originally created them.
