Jean-Bédel Bokassa, ruler of the Central African Republic from 1966 to 1979 was a bit of a fruit loop as well. During the last three years before he was overthrown, he styled himself as "His Imperial Majesty Bokassa I, Emperor of Central Africa by the will of the Central African people, united within the national political party, the MESAN".
In emulation of his hero Napoleon Bonaparte, he crowned himself emperor of the Central African Empire in a ceremony costing $20 million, practically bankrupting the country. His diamond-encrusted crown alone cost $5 million.
One of the more... unusual rules imposed in the early years of his rule, was that tom-tom playing was allowed only during the nights and weekends.
