Of any region in the world, the Horn of Africa is home to some of the oldest, richest, and varied religious traditions, featuring sites such as the Masjid al-Qiblatayn in Zeila and artefacts from the ancient Axumite kingdom in Tigray. For centuries, faith has and continues to play an integral part in the daily lives of most within the region, with Islam and Christianity the two dominant religions today. And in turn, spiritual life has naturally shaped the politics of the Horn, with elites having long grappled with how best to accommodate, co-opt, or suppress religious movements and identities. Over the centuries, this has encompassed Muslim leaders couching their fight in the rhetoric of jihad as well as the 'civilising' expansion of the Orthodox Christian Ethiopian Emperors into neighbouring regions in the 19th century.
