Yuhi III Mazimpaka (scientific orthography: Yuhi wa Gatatu Mazimpakâ) was the Mwami (King) of kingdom of Rwanda from 1735 to 1766.
He revealed from his dreams the coming of a pale race of people in many years after his death that would lead to the downfall of his kingdom.
King Yuhi III commissioned a construction of a three storeyed house made of tree trunks, reeds and grass straws at a place known as Kamonyi.
He suffered occasional mental illness due to his combination of intensive meditations/envisioning and the daily running of the Kingdom.
He died from a leg injury which he sustained from an attempt to dive from a high rock into a lake where he had gone to swim.
