The dry lands of Namibia were inhabited since early times by Bushmen, Damara, and Namaqua, and since about the 14th century AD by immigrating Bantu. It became a German Imperial protectorate in 1884 and remained a German colony until the end of World War I. In 1920, the League of Nations mandated the country to South Africa, which imposed its laws and, from 1948, its apartheid policy.
Namibia remained under South African administration during this time as South-West Africa. Following internal violence, South Africa installed an interim administration in Namibia in 1985. Namibia obtained full independence from South Africa in 1990, with the exception of Walvis Bay and the Penguin Islands, which remained under South African control until 1994.
Namibia has a population of 2.1 million people and a stable multi-party parliamentary democracy. Agriculture, herding, tourism and the mining industry – including mining for gem diamonds, uranium, gold, silver, and base metals – form the backbone of Namibia's economy. Given the presence of the arid Namib Desert, it is one of the least densely populated countries in the world. Approximately half the population live below the international poverty line, and the nation has suffered heavily from the effects of HIV/AIDS, with 15% of the adult population infected with HIV in 2007.
