Front: Mswati III (1968-), King of Swaziland 1986-present

Mswati III, born Makhosetive Dlamini, succeeded his father Sobhuza II as King of Swaziland at the age of 18. He is generally considered to be one of the last absolute monarchs in the world. The king lives a jet-set life with 13 wives, each with separate palaces, and 23 children. With a fortune estimated at $100 million, placing him on Forbes magazine's list of the 15 richest monarchs in the world, he rules in a country where nearly 70% of people live on less than $1 a day.
