Flag of Botswana

In 1885, Bechuanaland became a protectorate of the United Kingdom within its colonial empire. This occurred after the leaders of the Tswana people negotiated with the British to offer them protection from the Boers, who were invading their lands from the neighbouring South African Republic. In spite of this newfound protection, South Africa continued to pressure the British to allow them to annex Bechuanaland into their union. However, this did not occur, due to widespread opposition from the Batswana people, and Bechuanaland gained independence from Britain in 1966; the new nation was renamed Botswana.
Before it gained independence, Botswana did not have its own distinctive colonial flag, with the flag of the United Kingdom serving as the de facto flag of the protectorate. When Botswana's national flag was created in 1966, it was symbolically designed to contrast with the flag of South Africa, since the latter country was ruled under an apartheid regime. Hence, the black stripe with the white frame came to epitomize the peace and harmony between the people of African and European descent who reside in Botswana. The new flag was first hoisted at midnight on September 30, 1966, the day Botswana became an independent country. 
The light blue represents water—specifically, in its form of rain, as it is a precious resource in Botswana, which relies on agriculture and suffers from frequent droughts due to the dry and arid climate of the Kalahari Desert. The blue also alludes to the motto featured on the coat of arms of Botswana—Pula, which means "Let there be rain" in Setswana—as well as life, which is sustained by water.
The black band with the white frame has two meanings. Firstly, they symbolize the harmony and cooperation between the people of different races who live in Botswana, as well as the racial diversity of the country. Furthermore, they represent the stripes of the zebra, the national animal of Botswana.
