The area of present-day Tanzania has been inhabited since pre-historic times, first by hunter-gatherers, and since at least 2000 years ago by farmers. Travellers and traders from the Persian Gulf and India began visiting coastal areas in the early 1st millennium AD, and Arab trading posts were set up long before the 14th century. Portugal took control of some coastal areas and parts of Zanzibar from the 15th century, before Omani Arabs claimed Zanzibar in the mid 19th century, which subsequently played an important role in Arab-controlled slave and spice trades. The mainland part of Tanzania was part of German East Africa from 1884, while Britain took control of Zanzibar. After World War I, the part of German East Africa that became Tanzania (then called Tanganyika) was claimed by Britain. Tanganyika became independent in 1961, and Zanzibar in 1963, and they merged in 1964 to become Tanzania.
