Oyo Empire 17th century, Oyo began a long stretch of growth, becoming a major empire. Oyo never encompassed all Yoruba-speaking people, but it was the most populous kingdom in Yoruba history. The key to Yoruba rebuilding of Oyo was a stronger military and a more centralized government. Taking a cue from their Nupe enemies (whom they called "Tapa"), the Yoruba rearmed with armor and cavalry. Oba Ofinran, Alaafin of Oyo, succeeded in regaining Oyo's original territory from the Nupe. A new capital, Oyo-Igboho, was constructed, and the original became known as Old Oyo. The next oba, Eguguojo, conquered nearly all of Yorubaland.

The Jewish community among the Yoruba are often referred to as the Bnai Ephraim (Children of Ephraim). Most of them concentrated around various communities in Ondo state since the 1930s, about 2000 people in all. According to their traditions, they came to Nigeria by way of Morocco sometime in the 16th century after the expulsion of the Jews from Spain in 1492. Their language is a mixture of Moroccan Arabic with Yoruba, but with bits of Aramaic, such as ima for “mother.”
