The Serer religion or Serer spirituality (Serer: A ƭat Roog, meaning "the way of the Divine", "path of God", or "religious life"), is the original religious beliefs, practices, and teachings of the Serer people living in the Senegambia region in West Africa. The Serer religion believes in a universal supreme deity called Roog (or Rog). In the Cangin languages, Roog is referred to as Koox (or Kooh), Kopé Tiatie Cac, and Kokh Kox. Doctor of ethnology and lecturer in ethnosciences, Professor Simone Kalis writes that:
The Serer people are found throughout the Senegambia region. In the 20th century, around 85% of the Serer converted to Islam (Sufism), but some are Christians or follow their traditional religion. Despite resisting Islamization and jihads for almost a millennium - having been persecuted for centuries, most of the Serers who converted to Islam converted as recently as the 1990s, in part, trying to escape discrimination and disenfranchisement by the majority Muslim groups surrounding them, who still view the Serers as "the object of scorn and prejudice."
