context: Title: Tsandzile Ndwandwe

  Title: Sobhuza I
  Passage: Sobhuza I (also known as Ngwane IV, Somhlolo) (ca. 1780–1836) was king of Swaziland, from 1815 to 1836. Born around 1780, his father was Ndvungunye (also known as "Zikodze"), and his mother was Somnjalose Simelane. He was called Somhlolo, "the Wonder," upon his birth because his father Ndvungunye died as a result of being struck by lightning. When Sobhuza was king, Lojiba Simelane instead of his mother Somnjalose was Queen Mother because Somnjalose was an "inhlanti" or support bride to Lojiba. Somhlolo is a greatly revered king of Swaziland. He had his first royal capital or kraal at Zombodze in the Shiselweni region, but moved it north to new Zombodze in central Swaziland. Swazis celebrate Somhlolo Day every September 6 as their Independence Day and the national stadium is named Somhlolo stadium. Sobhuza was succeeded by his son Mswati II and his wife Tsandzile Ndwandwe as Queen Mother after a short regency by Queen Lojiba Simelane. Sobhuza by the time of his death a conquered a country claimed to be reaching modern day Barberton in the north, Carolina in the west, Pongola River in the south and Lubombo Mountains in the east.
