A major driver is attacks by radical Islamist militants, particularly in northern and northeastern Nigeria. Groups like Boko Haram (which means "Western education is forbidden" in Hausa) and the Islamic State West Africa Province (ISWAP) have waged insurgencies since 2009, explicitly targeting Christians as part of their goal to establish an Islamic caliphate under Sharia law. These groups view Christians as infidels and symbols of Western influence, leading to massacres, kidnappings, forced conversions, and the destruction of churches. For instance:
- In 2014, Boko Haram kidnapped over 200 mostly Christian schoolgirls in Chibok, many of whom were forced into marriage or slavery.
- Attacks often occur during Christian holidays, such as the 2023 Christmas Eve raids in Plateau State, where over 150 people were killed in coordinated assaults on villages.
- Clergy are frequent targets; priests have been abducted, tortured, or executed, as seen in the 2022 Pentecost Sunday church massacre in Owo, where over 40 worshippers died.
These groups have killed tens of thousands overall, but Christians are disproportionately affected in regions where they are minorities, such as the 12 northern states under Sharia law, where non-Muslims face discrimination and second-class status. Blasphemy laws in these areas have also led to mob violence, like the 2022 lynching of Christian student Deborah Samuel Yakubu for alleged insults against Islam.
