Botswana is named after the Tswana tribe that lives in the region. Before independence from Britain in 1966 it was known as Bechuanaland. Bechuanaland became a protectorate in 1885 because the British feared growing German and Boer influence over the area. The southern part of Bechuanaland was incorporated into Cape Colony and is now part of South Africa, but the northern part stayed separate. An oddity was that Bechuanaland was governed from Mafeking, which lies in South Africa. After independence Gaborone became the capital.
The British never handed Bechuanaland over to South Africa, especially after WW2 due to the apartheid policies that isolated South Africa diplomatically.
Botswana used British and South African currency until it introduced the Pula in 1976 at par with ZAR. The Pula proved a stronger currency that ZAR and now trades close to 10 to USD and 0.8 per Rand.
The first coin series was issued from 1976. Smaller size coins were introduced in 1998 with a small design update in 2013.
