Coat of arms of Botswana
The coat of arms of Botswana was adopted on 25 January 1966. The centre shield is supported by two zebras. The shape of the shield is that of traditional shields found in Southern Africa. On the top portion of the shield are three cogwheels that represent industry. The coat of arms is based on designs by Isabel Fawcus, whose husband Peter Fawcus was the Commissioner of Bechuanaland in 1960–65, and Shiela England. The three waves symbolize water, and reminds the viewer of the motto of the nation: "pula", which translates to "rain", but also good  luck, and is also the name of the nation's currency. This motto also highlights the importance of water to Botswana. The motto is inscripted on a blue ribbon placed at the bottom of the coat of arms. At the bottom of the shield is the head of a bull, which symbolises the importance of cattle herding in Botswana. The two zebras also symbolise the importance of wildlife, through tourism, in the national economy. Also, zebra have black and white stripes which represent equality of people of all colours in Botswana. The zebra on the right holds an ear of  sorghum, an important crop in the nation. The zebra on the left holds a tusk of ivory, symbolic of the former ivory trade in Botswana. There is also view that ivory tusk represents wild life preservation. Botswana has one of the highest elephant populations in Africa. Official description.
