The Independence Day of Botswana, commonly called Boipuso, is a national holiday observed in Botswana on September 30 of every year. The date celebrates Botswana's Declaration of Independence from the United Kingdom on September 30, 1966.
Independence Day is commonly associated with fireworks, parades, fairs, picnics, concerts, family reunions, and political speeches and ceremonies, in addition to various other public and private events celebrating the history, government, and traditions of Botswana. Independence Day is the National Day of Botswana.
The most powerful ruler was King Khama III, who had strong support from the British government, and was especially popular among evangelicals in Britain. He collaborated closely with the British military, and kept his vast, but underpopulated lands independent from intruders from South Africa.
Khama's eldest son was Sekgoma II, who became chief of the Bamangwato upon Khama's death in 1923. Sekgoma II's eldest son was named Seretse. Throughout his life Khama took several wives (each after the death of the former one). One of his wives, Semane, birthed a son named Tshekedi.
Sekgoma II's reign lasted only a year or so, leaving his son Seretse, who at the time was an infant, as the rightful heir to the chieftainship (Tshekedi was not in line to be chief since he did not descend from Khama’s oldest son Sekgoma II). So in keeping with tradition, Tshekedi acted as regent of the tribe until Seretse was old enough to assume the chieftainship. The transfer of responsibility from Tshekedi to Seretse was planned to occur after Seretse had returned from his law studies overseas in Britain.
