Southern Rhodesia was the name of the British colony situated north of the Limpopo River and the Union of South Africa. From its independence in 1965 until its extinction in 1980, it was known as Rhodesia. Since 1980 and the institution of a majority African government, the area has been renamed Zimbabwe and all traces of former British, Rhodesian, and white rule, laws, property, and nomenclature have been removed as part of President Robert Mugabe's policy of Africanization.

The territory 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 April 18, 1980, when the name Republic of Zimbabwe was formally proclaimed.

Rhodesia was named after Cecil Rhodes, the British empire-builder who was one of the most important figures in British expansion into southern Africa, and who obtained mineral rights in 1888 from the most powerful local traditional leaders through treaties such as the Rudd Concession and the Moffat Treaty signed by King Lobengula of the Ndebele.

World War I (WWI), which was predominantly called the World War or the Great War from its occurrence until 1939 (World War II), and the First World War or World War I thereafter, was a major war centred in Europe that began on 28 July 1914 and lasted until 11 November 1918. It involved all the world's great powers, which were assembled in two opposing alliances: the Allies (based on the Triple Entente of the United Kingdom, France and Russia) and the Central Powers (originally centred around the Triple Alliance of Germany, Austria-Hungary and Italy; but, as Austria–Hungary had taken the offensive against the agreement, Italy did not enter into the war). These alliances both reorganised (Italy fought for the Allies), and expanded as more nations entered the war. Ultimately more than 70 million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history. More than 9 million combatants were killed, largely because of enormous increases in lethality of weapons, thanks to new technology, without corresponding improvements in protection or mobility. It was the sixth-deadliest conflict in world history, subsequently paving the way for various political changes such as revolutions in the nations involved.
