His Majesty King Mswati III was born at the Raleigh Fitkin Memorial Hospital in Manzini, Swaziland, on 19th April, 1968, that is a few months before Swaziland attained independence from Britain. At birth, he was named Makhosetive (“King of All Nations”). Prince Makhosetive was educated at Masundvwini Palace School and later went to Sherborne School in the United Kingdom until 1986 when he returned to Swaziland to be installed King of Swaziland. According to tradition, his official name and title became Mswati III.
As a young boy, Prince Makhosetive enjoyed marching and drilling to the extent that when he was four years he wanted to become a member of the royal guard. A year later his dream was fulfilled when he became the first young cadet to join the Umbutfo Swaziland Defense Force (USDF). Boys of his age later joined him. Prince Makhosetive took his military training seriously. When he was not at school, he spent his spare time training with the soldiers at the Masundvwini Military Barracks near Etjeni royal residence.
Prince Makhosetive was introduced to the Swazi nation and the whole world at large as the Crown Prince in September 1983 and was crowned King of Swaziland on 25 April, 1986, at the age of 18, making him the youngest ruling Monarch in the world. The King and the Queen Mother of Indlovukazi (she-elephant), rule jointly.
