The Diaspora: Brazil, Cuba, Haiti and the Americas
Yoruba captives in the last decades of the Atlantic slave trade, Nagô in Brazil and Candomblé, the 1835 Malê revolt in Bahia, Lucumí in Cuba (Santería, Regla de Ocha, Ifa), Yoruba influences in Haitian Vodou and Trinidad's Orisha, returnees to Lagos and Sierra Leone, and orisa traditions in the United States and Europe today.
Across the Atlantic
Because the Yoruba wars peaked as the Atlantic trade's last decades unfolded, Yoruba captives were a large share of Africans landed in Bahia and Cuba in the 19th century. Their religion survived enslavement by blending with Catholic saints (Sango with Saint Barbara, Yemoja with the Virgin of Regla in Cuba) and by preserving Yoruba words, songs and Ifa verses as liturgy.
