The Ngindo of Tanzania, numbering approximately 638,000 people, are Engaged yet Unreached. They are a Bantu people of southeastern Tanzania's Liwale and Kilwa districts, whose homeland in what became the Selous Game Reserve endured 1800s Ngoni raids and later formed the heartland of the Maji Maji rebellion against German colonial rule. They mostly adhere to Sunni Islam and Ngindo is their primary language.
