Robert Mugabe arrested! Reestablishment of Rhodesia when?

On the evening of 14 November 2017, elements of the Zimbabwe National Army gathered around Harare, the capital of Zimbabwe, and seized control of the Zimbabwe Broadcasting Corporation and other areas of the city. The next day, they issued a statement saying that it was not a coup d'état and that President Robert Mugabe was safe, although the situation would only return to normal after they had dealt with the "criminals" around Mugabe responsible for the socio-economic problems of Zimbabwe.[1] Jacob Zuma, the President of South Africa, phoned Mugabe and confirmed that Mugabe was "fine", but under house arrest.[2]
The coup took place amid tensions in the ruling ZANU–PF party between former Vice President Emmerson Mnangagwa (who was backed by the army) and First Lady Grace Mugabe (who was backed by the younger G40 faction) over who would succeed the elderly President Mugabe. A week after Mnangagwa was fired and forced to flee the country, and a day before troops moved into Harare, army chief Constantino Chiwenga issued a statement that purges of senior ZANU-PF officials like Mnangagwa had to stop.[3]
