The Budugum of Chad, numbering approximately 44,500 people, are Engaged yet Unreached. They are a Chadic-speaking Masana subgroup whose ancestors are said to have migrated from Yemen through Egypt and Sudan to settle near Lake Chad by the early 9th century, later crossing into Cameroon for protection from Tripoli-based slave raiders. They mostly adhere to Ethnoreligion and Masana is their primary language.
