King Mwanawina III was the 20th Litunga of Barotseland who ruled Barotseland from 1948-1968. He was born in 1888 at Lealui, and was educated at PMS missionary school in Barotseland, Lovedale college and University of Cape Town in South Africa.

He served in the great war as a commander of Barotse carriers in East African campaign. He excelled, and was, therefore, honored with Allied victory and British war medals. He also attended the coronation ceremony of Queen Elizabeth II in London. In 1959 he was bestowed with the title of Knight Commander of the British Empire (KBE).

He was pressured into signing the Barotseland Agreement 1964, which attempted to absorb Barotseland by Northern Rhodesia to pave way for the creation of the so called "One Zambia One Nation".

This attempt of One Zambia One Nation which sought to make Barotseland an Autonomous region with her own Barotse Government failed even before it started as barely 18 months after signing it Kaunda's treacherous government repudiated and abrogated the agreement and has since subjugated the region of Barotseland to a mere province they called western province in what is clearly Black on Black colonization.
