Context paragraphs:
Rhodesia (region): Rhodesia is a historical region in southern Africa whose formal boundaries evolved between the 1890s and 1980.  Demarcated and named by the British South Africa Company (BSAC), which governed it until the 1920s, it thereafter saw administration by various authorities.  It was bisected by a natural border, the Zambezi.  The territory to the north of the Zambezi was officially designated Northern Rhodesia by the Company, and has been Zambia since 1964; that to the south, which the Company dubbed Southern Rhodesia, became Zimbabwe in 1980.  Northern and Southern Rhodesia were sometimes informally called "the Rhodesias".

Politics of Zambia: The politics of Zambia takes place in a framework of a presidential representative democratic republic, whereby the President of Zambia is head of state, head of government and leader of a multi-party system.  Executive power is exercised by the government, while legislative power is vested in both the government and parliament.  Formerly Northern Rhodesia, Zambia became a republic immediately upon attaining independence in October 1964.

Flag of Zambia: The flag of Zambia is the national flag of Zambia.  It was adopted upon independence on October 24, 1964.  Before that, Zambia was the British protectorate of Northern Rhodesia and used a defaced Blue Ensign as its flag.

1960s in Rhodesia: Iain Peter Butchart, a cricketer, was born in Bulawayo on 9 May 1960.  Broadcasting of television started in November.  The Zimbabwe African People's Union (ZAPU) was formed in 1961 with Joshua Nkomo as leader.  The Rhodesian Front won the general elections of 1962 on 14 December.  Winston Field then became the Prime Minister of Rhodesia.  The Zimbabwe African National Union (ZANU) was formed in 1963 with Robert Mugabe as Secretary.  The Federation of Rhodesia and Nyasaland was dissolved on 31 December 1963 as Zambia and Malawi moved towards independence.  The government placed Joshua Nkomo, leader and founder of the Zimbabwe African Peoples Union, under restriction on 16 April 1964.  Northern Rhodesia gained its independence and Southern Rhodesia became the colony of Rhodesia on 24 October.

Copperbelt strike of 1935: The Copperbelt strike of May 1935 was a strike by African mineworkers in the Copperbelt Province of Northern Rhodesia (now Zambia) on 29 May 1935 to protest taxes levied by the British colonial administration.  The strike involved three of the province's four major copper mines: those in Mufulira, Nkana and Roan Antelope.  Near the latter, six protesters were killed by police and the strike ended.  Although it failed, the strike was the first organized industrial agitation in Northern Rhodesia and is viewed by some as the first overt action against colonial rule.  It caught the attention of a number of African townsmen, leading to the creation of trade unions and African nationalist politics, and is seen as the birth of African nationalism.

Colin Morris (Methodist minister): Colin Manley Morris (born 1929) is an English Methodist minister.  Born into a mining family, after his ordination he served the Methodist Church in Zambia (then Northern Rhodesia) for fifteen years.  He stood out for racial integration within the church, became a close friend of the leader of the independence movement, Kenneth Kaunda, and was closely involved in the formation of the United Church in Zambia soon after the country became independent.  He has always espoused an explicitly anti-racist and socialist position and argued that it represents the authentic spirit of Christianity.

Prime Minister of Zambia: The Prime Minister of Zambia was the head of government of Zambia.  From 1973 to 1975, Mainza Chona was the first person to hold the position following independence from the United Kingdom (Kenneth Kaunda was the first and only Prime Minister of Northern Rhodesia in 1964, before it became independent as Zambia).

Northern Rhodesia Regiment: The Northern Rhodesia Regiment (NRR) was a multi-battalion British colonial regiment raised from the protectorate of Northern Rhodesia.  It was formed in 1933 from elements of the Northern Rhodesia Police, which had been formed during Company rule in 1912.  Made up of black rank-and-filers and white officers, its motto was "Different in Race, Equal in Fidelity".

Northern Rhodesia: Northern Rhodesia was a protectorate in south central Africa, formed in 1911 by amalgamating the two earlier protectorates of Barotziland-North-Western Rhodesia and North-Eastern Rhodesia.  It was initially administered, as were the two earlier protectorates, by the British South Africa Company, (BSAC), a chartered company on behalf of the British government.  From 1924 it was administered by the British government as a protectorate under similar conditions to other British-administered protectorates, and the special provisions required when it was administered by BSAC were terminated.
