Who was the longest lived monarch?

I have had a search through the archives but couldn't locate anything.

Has any monarch [not consort] lived longer that King George I of Tonga
(4 Dec 1797 - 18 Feb 1893) - i.e. 95 years?

King Pepi II of Egypt is credited with living to 100 (after a reign of 94 years).

Has any European monarch lived longer than Queen Juliana of the
Netherlands (30 Apr 1909 - 20 Mar 2004) i.e. 94 years?

Stephen Stillwell / Tom Wilding...

King Sobhuza II of Swaziland always deserves mention when people talk about
longevity. Born 22 July 1899, king 10 November 1899 - died 21 August 1982.
So he lived 83 years 1 month, all but about 4 months of them as king.

I am happy to go back as far as possible - but is there not some doubt
as to the length of Pepi's reign, and the possibility that is was some
64, rather than 94, years?

The lower figure seems to be there largely because it is intiutively
more believable, but the vast majority of the authorities of the
chronology of the Old Kingdom accept the reign of 94 years as a fact.
There is ample contemporary evidence that he acceded to the throne as a
small child, and also reasonable contemporary evidence that he actually
lived to be a very old man.

Jan Böhme

Both of which are true, but it is not true that the doubts raised about the
reignlength are there "largely because it is intiutively
more believable". There are two specific reasions for doubting it:
officials and family members are known who were alive both when he was a
young man and near the end of the reign, and the highest dated document is
closer to 64 years than 94 years.
