"Wazaramo" is the preferred name for the people who live in the coastal area of Tanzania, in the vicinity of the capital city, Dar es Salaam. "Wazaramo" refers to the ethnic group, "Mzaramo" to an individual, and "Kizaramo" to the language. Today the Zaramo are predominantly Muslims, but they have not been Muslims for very long. In the period between 1857 and 1881, when explorers passed through Zaramo area, nowhere was it mentioned that the Zaramo were Muslims. Instead, they went to worship at the cave of Kolelo. The big movement toward Islam came during two periods, from around 1890 to 1900 and from 1910 to 1925. Islam accommodated itself very well to Zaramo traditional religious and social structure.
