Klemens von Metternich
Klemens Wenzel Nepomuk Lothar, Prince von Metternich-Winneburg zu Beilstein, KOGF (; 15 May 1773 – 11 June 1859) was an Austrian diplomat who was at the center of European affairs for four decades as the Austrian Empire's foreign minister from 1809 and Chancellor from 1821 until the liberal Revolutions of 1848 forced his resignation.
Sobhuza II
One of Sobhuza's sons-in-law was Goodwill Zwelithini kaBhekuzulu, King of the Zulus of South Africa, who married the Swazi king's daughter, Princess Mantfombi (born at Siteki in 1956, betrothed in 1973), at Nongoma in June 1977. Another in-law is Zenani Mandela, the daughter of former South African President Nelson Mandela, who belonged to a cadet branch of the Thembu dynasty which reigns as paramount chiefs in the Transkei. She wed Sobhuza's son, Prince Thumbumuzi Dlamini who, although an older half-brother of Mswati and Mantfombi, did not inherit the Swazi throne, instead launching, with his wife, an enterprise in the United States.
