Enriched with the diverse cultures, languages, and beliefs of more than 120 ethnic groups—from the ochre-painted Maasai Warriors and the mystical, forest-dwelling and solitary Ha to the coffee-trading Haya along the shores of Lake Victoria—Tanzania has remained harmonious partly because nearly everyone speaks Swahili in addition to their native tongue. Primary schooling in Tanzania is in Swahili, though secondary schooling switches to English. Tanzania’s currency is the Tanzania shilling, but U.S. dollars are widely accepted for tourist services and at international hotels. Tanzanians are generally a very peaceful, laid-back people, made up of Christians, Muslims, Hindus, and some remaining tribal cultures. Sunday is still a day when most shops close early regardless of the area’s religion.
