The South African King Buyelekhaya Dalindyebo began his jail term on Wednesday.
The regent was tried and convicted of culpable homicide, assault with intent to do grievous bodily harm, arson, and kidnapping.
King Dalindyebo was originally convicted of the crime in 2009, but was granted bail repeatedly. However, a court recently struck down his latest attempt to seek bail and ruled that he start his 12 year sentence immediately.
His charges are related to his treatment of his subjects from 1995 to 1996. The South African regent will be serving out his prison term at the Wellington Prison outside Mthatha a city in the Eastern Cape region of South Africa.
