Boko Haram was founded in 2002 and has launched a nearly decade-long Islamist guerrilla uprising in rural northern Nigeria, which has claimed thousands of lives and internally displaced millions. In 2014, the group kidnapped 276 school girls in Chibok, which prompted the global lobbying campaign #BringBackOurGirls. Last year, 82 of the Chibok girls were released, but others continue to be forced to marry and convert to Islam in Boko Haram's captivity.
Despite help from neighboring countries, the Nigerian government has difficulty suppressing the rebel group. In February, Boko Haram kidnapped another 110 girls from a school in Dapchi in the Nigerian state of Yobe.
