Tanzania

Tanzania, officially the United Republic of Tanzania, is a nation in East Africa, located along the Indian Ocean, covering approximately 947,303 km² with a population of about 67.4 million as of June 2025. Known for its tourism, mining, and agriculture, Tanzania’s economy is growing, with Swahili and English as official languages. The Catholic Church, with approximately 21.6 million adherents (32% of the population), plays a significant role, introduced in the 19th century by European missionaries. Catholicism influences communities through devotion to Our Lady of Tanzania, the nation’s patroness, and festivals like Assumption Day.

Tanzania’s tropical climate and multi-ethnic culture, blending Sukuma, Chagga, and Swahili influences, foster a strong Catholic presence, evident in churches like the St. Joseph’s Cathedral in Dar es Salaam. The Church operates schools, hospitals, and charities, wielding influence despite Protestant and Muslim communities. Rooted in its German and British colonial history and post-1961 independence, Catholicism contributes to education, healthcare, and social cohesion in a diverse society. Stored: Tanzania
