Falola's most recent research traces the globalization of the Yoruba people in terms of history, culture, transformation, and change. Undoubtedly, this approach is a vast advancement on all previous similar projects, including that of Samuel Johnson's History of the Yoruba, which is a landmark work on the Yoruba in the late nineteenth century. The Yoruba are currently found in the southwest part of Nigeria, the Republic of Benin, Togo, Ghana, and Ivory Coast. Falola sets himself a dual problem: “What the Yoruba receive from the outside world (as in the cases of Islam and Christianity)” and “What they contribute to the world beyond them” (as in the case of Orisa and the Aladura/Pentecostal churches of Britain and the United States; Abimbola, 1973, 1975, 1976a, 1976b, 1977, 1981, 1998; Abiodun, 1975; Abraham, 1962; Addie, 1990; Adebisi, 1986; Adedeji, 1966; Adegbile, 1999; Adelugba, 1981; Adeoye, 1979, 1985; Adewoye, 1987; Afolabi, 2001; Afolayan, 2000; Ahye, 1981; Aiyejina & Rawle, 1999; Ajayi, 1974, 2000; Ajuwon, 1981; Akanmu, 1999; Akinjogbin, 1972; Akinjogbin, 2002, Akinjogbin, 1976; Akinyemi, 2004; Alade, 1992, 1995; Andrew, 1987; Atanda, 1980, 1973; Awe, 1973; Aweda 2002; Awolalu, 2001, 1979; Ayodeji, 1999; Babalola, 1966; Babayemi, 1973; Babayemi, 1979, 1976; Badejo, 1982, 2004; Balderson et al., 2002; Bamidele, 2003; Barber, 1989, 1981, 1979, 1984; Barnes, 1989; Bascom, 1973, 1969, 1972, 1980; Bastide, 1945, 1978, 1986; Baudin, 1884; Beier, 1994, 1959, 1980, 1960; Benkomo, 2000; Bettelheim, 2001; Bewaji, 1992; Biobaku, 1975; Birth, 1999; Bolaji, 1962; Bomfim, 1940; Borghero, 1865, 1997; Bourguignon, 2000; Bowen, 1858; Braga, 1992, 1995; Brain, 1980; Brereton, 1979; Browker, 1997; Brown, 2003; Burket, 1985).
In seeking to understand the origins, culture, and history of the Yoruba, Falola adopts the Akan concept of Sankofa, which means understanding the present via the lens of history. In exploring the rich historical experience of the Yoruba people, Falola's work surveys events spanning at least ten centuries. Beginning from ancient times, the Yoruba had interactions with their neighbors such as the Borgu, Benin, Nupe, Dahomey, the Hausa states and the Songhai Empire. Here, we glean evident traces of the multiculturalism and cosmopolitanism that would come to characterize the lives of many diasporic Yoruba.
