Tanzania

Since 1964, there has been one constitution, but two governments. Zanzibar exercises autonomy over its internal affairs. A Union government is responsible for common defense, foreign affairs, and other matters, such as higher education, civil aviation, postal services, and telecommunications. Primary, secondary, and vocational education are regulated separately; agriculture and industry are also considered internal matters on Zanzibar and the mainland. Tanzania is divided into 25 administrative regions. Agriculture and tourism are the principle economic activities, although industry is growing steadily.
