Shoshenq III was the seventh king of the Twenty-second Dynasty. He is thought to have ruled for fifty-two years. During the twenty-
eighth year of his reign, an Apis bull was born. This is recorded on the Serapeum stela by a priest named Pediese. His tomb was found
at Tanis and was similar in structure to those of Psusennes I and Osorkon II.
King Usermaatre Setepenre or Usimare Setepenamun Shoshenq III ruled Egypt's 22nd Dynasty for 39 years according to
contemporary historical records. Two Apis Bulls were buried in the fourth and 28th years of his reign and he celebrated his
Heb Sed Jubilee in his regnal year 30. Little is known of the precise basis for his successful claim to the throne since he
was not a son of Osorkon II and Shoshenq's parentage and family ties are unknown.
From Shoshenq III's eighth regnal year, his reign was marked by the loss of Egypt's political unity, with the appearance of
Pedubast I at Thebes. Henceforth, the kings of the 22nd Dynasty only controlled Lower Egypt. The Theban High Priest Osorkon
B (the future Osorkon III) did date his activities at Thebes and (Upper Egypt) to Shoshenq III's reign but this was solely
for administrative reasons since Osorkon did not declare himself king after the death of his father, Takelot II. On the
basis of Osorkon B's well known Chronicle, most Egyptologists today accept that Takelot II's 25th regnal year is equivalent
to Shoshenq III's 22nd year.
Shoshenq III married Djed-Bast-Es-Ankh, the daughter of Takelot, a High Priest of Ptah at Memphis, and Tjesbastperu,
Osorkon II's daughter. He had at least 4 sons and 1 daughter: Ankhesen-Shoshenq, Bakennefi A, Pashedbast B, Pimay the
'Great Chief of the Ma', and Takelot C, a Generalissimo. A certain Padehebenbast may also have been another son of Shoshenq
III but this is not certain. They all appear to have predeceased their father through his nearly four decade long rule.
Shoshenq III's third son, Pimay ('The Lion' in Egyptian), was once thought to be identical with king Pami ('The Cat' in
Egyptian), but it is now believed that they are two different individuals, due to the separate orthography and meaning of
their names. Instead, it was an unrelated individual named Shoshenq IV who ultimately succeeded Shoshenq III.
Shoshenq III was buried in the looted Royal Tomb NRT V at Tanis.
