Longest Reign!!

I found another list with contestants...

we have Pepi II of Egypt, whose dates are not nailed
down that firmly but seem to have been 94 years mainly in the 23rd
century BC...supposedly from age about 6 to about 100 as Decebal said also.

Other unclearly documented claims are those of:

 Musoma Kanjio(1856-1963) chiefship at his 8 in 1864 and held it for over 98 years, and

Minhti, king of the Burmese predecessor state of Arakan 1279-1374....earlier editions of the Guinness Book also noted almost certainly vastly inflated claims of 101 and 83 years for the 6th  Emperor K�an and 5th Emperor K�sh�, Emperors of Japan.

Apart from them we have:

Raja Sawai Basavalinga I of Sundem: 1763 - 1843: 79 years +

Prince Heinrich XI of Reuss-Greiz: 17.3.1723 - 28.6.1800: 77 years 103
days (as Count until 12.5.1778)

Naik Madhoji Rao Nimbalkar of Phaltan: 7.12.1841 - 17.10.1916: 74
years 315 days

Maharaja Bhagwatsinhji of Gondal: 14.12.1869 - 10.3.1944: 74 years 87
days

Raja Bishan Chandra Jenamani of Rairakhol: 1825 - 1900: 74 years +

Pr. Georg I Wilhelm of Schaumburg-Lippe: 13.2.1787 - 21.11.1860: 73
years 250 days (as Count until 18.4.1807)

King Alfonso Henry of Portugal: 30.4.1112 - 6.12.1185: 73 years 220
days (as Count until 1140)

Grand Duke Karl Friedrich of Baden: 12.5.1738 - 10.6.1811: 73 years 29

King Louis XIV of France: 14.5.1643 - 1.9.1715: 72 years 110 days

Prince John II of Liechtenstein: 12.11.1858 - 11.2.1929: 70 years 91
days

Grand Duke Carl August of Saxe-Weimar und Eisenach: 28.5.1758 -
14.6.1828: 70 yrs 17 days (as Duke until 21.4.1815)

Maharaja Jagatjit Singh of Kapurthla: 1877 - 1948: 70 years +

Honourable mentions:

King Louis II of Etruria: reigned 27.5.1803 - 10.2.1807; died
16.4.1883: 79 yrs 324 days later

Duke Bernard II of Saxe-Meiningen: reigned 24.12.1803 - 20.9.1866;
died 3.12.1882: 78 years 344 days later

King Michael of Romania: reigned 20.7.1927 - 8.6.1930 & 6.9.1940 -
30.12.1947; living 7.1.2002: 74 years 171 days later

Queen Wilhelmina of the Netherlands: reigned 23.11.1890 - 4.9.1948;
died 28.11.1962: 72 years 5 days later

71 years 204 days later

Queen Isabella II of Spain: reigned 29.9.1833 - 30.9.1868; died
9.4.1904: 70 years 193 days later

For Persia, it was Shapur the Great who reigned from 309 to 379 AD (70 years).

According to tradition, Pepi II was the last ruler of Egypt's 6th Dynasty, and in fact the last significant ruler of the Old Kingdom prior to the onset of what Egyptologists call the Fist Intermediate Period. We are told that his reign of possibly 94 (some Egyptologist believe 64) years was the longest in ancient Egyptian history.  He seems to have come to the throne at about the age of six, and would therefore have lived until the age of one hundred.  However, because of the onset of the First Intermediate Period, the latter part of his reign was probably ineffectual, perhaps at least somewhat due to his advanced age. Both the Oxford History of Ancient Egypt and Peter A. Clayton, have his reign lasting from 2278 until 2184 BC. 

So which Monarch had the longest reign ever???

From what i found until now Louis XIV reigned from 1643 to 1715 (72 years) but its likely someone must have reigned longer. 

Louis XIV (Louis-Dieudonn��) (September 5, 1638 �C September 1, 1715) reigned as King of France and King of Navarre from May 14, 1643 until his death.

From women, Empress Kojun of Japan seems to be ahead with 75 years totally.

Her Imperial Majesty Empress Kojun of Japan was born Princess Kuni Nagako (jp: ��߃�m����Ů�� kuni no miya nagako jo��) (March 6, 1903 - June 16, 2000). She was the consort of the Showa Emperor, and mother of HIM the Emperor Akihito.

The Empress Nagako, known posthumously as Empress K��jun (�㴾�ʺ� k��jun k��g��), was the longest lived empress consort (k��go) in Japanese history. She was Crown Princess from 26 January 1924 to 25 December 1926, Empress from 26 December 1925 to 7 January 1989, and Empress Dowager from 7 January 1989 to 16 June 2000.

Any ideas for longer reigns???
