Context paragraphs:
Godfrey Huggins: Godfrey Martin Huggins, 1st Viscount Malvern (6 July 1883 – 8 May 1971) was a Rhodesian politician and physician.  He served as the fourth Prime Minister of Southern Rhodesia from 1933 to 1953 and remained in office as the first Prime Minister of the Federation of Rhodesia and Nyasaland until 1956, becoming the longest serving prime minister in British Commonwealth history.

Tiyo Soga: Tiyo Soga (1829 – 12 August 1871) was a South African journalist, minister, translator, missionary, and composer of hymns.  Soga was the first black South African to be ordained and worked to translate the Bible and John Bunyan’s classic work "Pilgrim’s Progress" into his native Xhosa language.

List of Prime Ministers of the United Kingdom: The Prime Minister of the United Kingdom is the head of the Government of the United Kingdom, and chairs Cabinet meetings.  There is no specific date when the office of Prime Minister first appeared, as the role was not created but rather evolved over a period of time.  The term was used in the House of Commons in 1805 and it was certainly in parliamentary use by the 1880s, and in 1905 the post of Prime Minister was officially given recognition in the order of precedence.  Modern historians generally consider Sir Robert Walpole, who led the government of Great Britain from 1721 to 1742, as the first Prime Minister.  Walpole is also the longest-serving Prime Minister by this definition.  However, Sir Henry Campbell-Bannerman was the first Prime Minister and Margaret Thatcher the longest-serving Prime Minister to have been officially referred to as such.

The Word of a Gentleman: The Word of a Gentleman (1981) (later retitled "Undercut") was the third of five novels written by Peter Niesewand, the South African journalist who spent 73 days in solitary confinement for his coverage of Ian Smith's government in Rhodesia (now Zimbabwe).  Set in the fictional former British colony of St David's Island, it has no principal protagonists beyond the corrupt trio of Claud Montrose, Alec Clifton, and Stephen Luther, but the subversive influence of the American agent Clive Lyle is progressively revealed as the story unfolds.  The fate of the unjustly imprisoned Stephen Ayer and his wife Nora are the focus of many chapters (and the book opens with a quotation from Oscar Wilde's "The Ballad of Reading Gaol"); these reflect Niesewand's detention by Desmond Lardner-Burke under P. K. van der Byl and Smith, and his subsequent deportation, leaving behind his wife of three years, Nonie Niesewand (née Fogarty).

Colonial history of Southern Rhodesia: The territory of 'Southern Rhodesia' was originally referred to as 'South Zambezia' but the name 'Rhodesia' came into use in 1895.  The designation 'Southern' was adopted in 1901 and dropped from normal usage in 1964 on the break-up of the Federation of Rhodesia and Nyasaland, and Rhodesia became the name of the country until the creation of Zimbabwe Rhodesia in 1979.  Legally, from the British perspective, the name Southern Rhodesia continued to be used until 18 April 1980, when the name Republic of Zimbabwe was formally proclaimed.  The colonial history of Southern Rhodesia lasted from the British government's establishment of the government of Southern Rhodesia on 1 October 1923, to Prime Minister Ian Smith's unilateral declaration of independence in 1965.

Heidi Holland: Heidi Holland (6 October 1947 – 11 August 2012), also known as Heidi Hull (during her first marriage), was a South African journalist and author who had been involved in the journalism industry for over 30 years.  She edited "Illustrated Life Rhodesia", worked as a freelance writer on publications such as "The Sunday Times", "The Telegraph", "International Herald Tribune", "The New York Times" and "The Guardian", and had also worked on research projects for British television documentaries.  She was the author of various books, such as "Dinner with Mugabe", an account of her meetings with Robert Mugabe, president of Zimbabwe.  Previously she released "The Colour of Murder", a critical analysis of the 2002 van Schoor murder trials in South Africa.  She also released a book based on the history of South Africa's ruling party, "The Struggle: A History of the African National Congress".  She was found dead of an apparent suicide in her home near Johannesburg.

Victoria Falls Conference (1975): The Victoria Falls Conference took place on 26 August 1975 aboard a South African Railways train halfway across the Victoria Falls Bridge on the border between the unrecognised state of Rhodesia (today Zimbabwe) and Zambia.  It was the culmination of the "détente" policy introduced and championed by B. J. Vorster, the Prime Minister of South Africa, which was then under apartheid and was attempting to improve its relations with the Frontline States to Rhodesia's north, west and east by helping to produce a settlement in Rhodesia.  The participants in the conference were a delegation led by the Rhodesian Prime Minister Ian Smith on behalf of his government, and a nationalist delegation attending under the banner of Abel Muzorewa's African National Council (UANC), which for this conference also incorporated delegates from the Zimbabwe African National Union (ZANU), the Zimbabwe African People's Union (ZAPU) and the Front for the Liberation of Zimbabwe (FROLIZI).  Vorster and the Zambian President Kenneth Kaunda acted as mediators in the conference, which was held on the border in an attempt to provide a venue both sides would accept as neutral.

Super Zimbabwe African People's Union: The Super Zimbabwe African People's Union was a militant organization, made up of former members of the Rhodesian Security Forces, which operated in Zimbabwe in the 1980s.  Super ZAPU members worked for either Ian Smith, the former Prime Minister of Rhodesia; Abel Muzorewa, the first and only Prime Minister of Zimbabwe Rhodesia; Ndabaningi Sithole, the founder of the Zimbabwe African National Union; or the apartheid Government of South Africa.

Ian Smith: Ian Douglas Smith, GCLM, ID (8 April 1919 – 20 November 2007) was a politician, farmer, and fighter pilot who served as Prime Minister of Rhodesia (or Southern Rhodesia) from 1964-1979.  The country's first premier not born abroad, he led the predominantly white government that unilaterally declared independence from the United Kingdom in 1965, following prolonged dispute over the terms.  He remained Prime Minister for almost all of the fourteen years of international isolation that followed, and oversaw Rhodesia's security forces during most of the Bush War, which pitted the unrecognised administration against communist-backed black nationalist guerrilla groups.  Smith, who has been described as personifying white Rhodesia, remains a highly controversial figure—supporters venerate him as a man of integrity and vision "who understood the uncomfortable truths of Africa", while critics describe an unrepentant racist whose policies and actions caused the deaths of thousands and contributed to Zimbabwe's later crises.

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.
