Apparently Khadafi’s official title is “The Revolutionary Leader” which interestingly enough has no official legal definition in the Libyan government. I guess the title means “the job Khadafi has” and the powers of office are “whatever he can get away with”.
Khadafi incidentaly is not the official head of state of Libya. That would be Zintani Muhammad az-Zintani, who is the Secretary General of the People’s Congress.
I think he was a sergeant when he led the coup. However, if it’s the same one I recall in a newspaper article, he soon promoted himself to a 5-star general.
Similarly, Sgt. Idi Amin became Field Marshal Dr. Idi Amin upon “winning” Uganda’s presidency.
The guy who led the 1980 coup in Liberia was Master Sergeant Samuel K. Doe, who promoted himself to General accordingly.
As far as self elevation and accumulation of exotic titles is concerned, Idi Amin Dada is an interesting case. As well as raising himself to the rank of Field Marshal he awarded himself military honours such as the Victoria Cross, Distinguished Service Order and Military Cross (all of which you normally get for unusual heroism in battle) and a range of titles including President for Life, Doctor, Lord of All the Beasts of the Earth and Fishes of the Sea, King of the Scots and Conqueror of the British Empire in Africa in General and Uganda in Particular.
That situation is actually a little different. The Communist Party was the undoubted source of political power in the Soviet Union, and its general secretary was usually the most powerful figure in the Soviet nation and its de facto ruler. But the Party was neither the state nor the government, each of which had its own head, so the general secretary was neither the head of state nor the head of government unless he also acquired one of those titles:
From Library of Congress, “Soviet Union–A Country Study”, ch. 7. The head of government was the chairman of the Presidium of the Council of Ministers and, as Little Nemo points out, Stalin occupied that office–as did several other Party general secretaries, until the practice was banned:
Id., ch. 8.
I wrote earlier that I couldn’t think of a case where the same person held independent (in the sense of constitutionally distinct) titles as head of state and head of government at the same time. I was overlooking an obvious one: Adolf Hitler, who acquired the Weimar Republic’s presidency after having been appointed as chancellor. As paperbackwriter has pointed out, another example is Saddam Hussein. What a great little club.
Earl Snake-Hips Tucker, Idi Amin was a Brigadier (just plain Brigadier, British-style, not "General) when he overthrew Milton Obote to take over Uganda (yes, he was a real career soldier).
Lt. Col. G/Kh/Qaddafi was promoted to full Colonel the year after his coup, but it so happens part of his revolution was the temporary elimination of the general/Flag ranks. Eventually Lybia reinstated the ranks (only up to LTG), and in the late 70s Muammar was placed on the list for Major General but declined to actually accept the promotion.
In the USSR, it was as brian quotes until 1977 – with actually a President, a PM, and a GS of CPSU – but in 77 Brezhnev went ahead and took the Presidency again. Gorby did the same, only that he had many of the powers he held as GS officially reclassified as being those of the office of the President – a move that was mirrored at the Russian Republic level by Yeltsin, before the collapse.
