Are the Igbo people of Nigeria really Jewish?

In southeast Nigeria, many Igbo people keep kosher, pray in synagogues, and celebrate Jewish holidays. Known for their advanced metalwork and democratic traditions, as well as ancient Israelite customs including circumcision and scapegoat rituals, the Igbo have blended ancient African and Jewish traditions for centuries, sparking debates on their true identity. When British colonialism introduced antisemitism into Africa, leading to the persecution of the Igbo people and the brief secession of the Republic of Biafra, the question of to what extent they should be accepted as part of the Jewish people became all the more pertinent.
