List of Famous people with last name I

Tigranes I of Armenia was a King of Armenia at the end of 2nd and the beginning of 1st century BC. Few records have survived about his and his predecessor Artavasdes I's reign, which has led to some confusion. Some modern scholars have doubted that such a king reigned at all. Contrary to them other researchers, such as Manandian, Lang and Adalian consider him a real figure but differ or are uncertain on the exact dates of his reign. Although it has been proposed that Tigranes I reigned from 123 BC to 96 BC, this view has been criticized. Another suggestion is that Tigranes I ruled in 120 BC - 95 BC and this has been recently corraborated by historian Christian Marek.

Sobhuza I was king of Eswatini, from 1815 to 1836. Born around 1780, his father was Ndvungunye, 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 Eswatini. He had his first royal capital or kraal at Zombodze in the Shiselweni region, but moved it north to new Zombodze in central Eswatini. 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 had conquered a country claimed to reach to modern day Barberton in the north, Carolina in the west, Pongola River in the south and Lubombo Mountains in the east.
