Seti II (or Sethos II), was the fifth ruler of the Nineteenth dynasty of Egypt and reigned from c. 1200 BC to 1194 BC. His throne name, Userkheperure Setepenre, means "Powerful are the manifestations of Re, the chosen one of Re.' He was the son of Merneptah and Isetnofret II and sat on the throne during a period known for dynastic intrigue and short reigns, and his rule was no different. Seti II had to deal with many serious plots, most significantly the accession of a rival king named Amenmesse, possibly a half brother, who seized control over Thebes and Nubia in Upper Egypt during his second to fourth regnal years.
Evidence that Amenmesse was a direct contemporary with Seti II's rule—rather than Seti II's immediate predecessor —includes the fact that Seti II's royal KV15 tomb at Thebes was deliberately vandalised with many of Seti's royal names being carefully erased here during his reign. The erasures were subsequently repaired by Seti II's agents. This suggests that Seti II's reign at Thebes was interrupted by the rise of a rival: king Amenmesse in Upper Egypt. Secondly, the German scholar Wolfgang Helck has shown that Amenmesse is only attested in Upper Egypt by several Year 3 and a single Year 4 ostracas here; Helck also noted that no Year 1 or Year 2 ostracas from Deir El Medina could legitimately be assigned to Amenmesse's reign. This conforms well with the clear evidence of Seti II's control over Thebes in his first two years which is documented by various documents and papyri. In contrast, Seti II is absent from Upper Egypt during his third and fourth years which are notably unattested here—presumably because Amenmesse controlled this region during this time.
