The United Republic of Tanzania is formed by Tanganyika and the island of Zanzibar. Like many other african states, Tanzania is a mix of more than 100 different ethnicities. The Bantu ethnicity is among the prevailing and dates back from ancient Arab influences, as evidenced by the spoken language, Swahili, which has several Arabic appeals. Even the colonial era has left a strong imprint, making the English language very widespread among the population, which is 35% of the Christian religion. The east coast of Tanzania and the island of Zanzibar are predominantly Muslim. Few countries offer Tanzania's geographical variety from the very high peaks of Kilimanjaro to the Serengeti park to the heavenly beaches of Zanzibar. Both Kilimanjaro National Park and Serengeti are Unesco World Heritage Sites, due to their wealth of flora and fauna.
