===Egyptian Revolt and death (206–204 BC)===
{{main|Hugronaphor}}
Sometime after the end of the Fourth Syrian War, revolts broke out in Egypt itself. Fighting took place in the north of the country in the [[Nile Delta|Delta]] and separately in [[Upper Egypt]], where fighting led to the interruption of building work on the Temple of Horus at [[Edfu]] in 207–206 BC.<ref>Edfu IV.8.1–7, VII.7.5–7.</ref> The reasons for these revolts are unclear. The Hellenistic historian [[Polybius]] argued that they were a natural result of Ptolemy IV's decision to arm the Egyptians during the Fourth Syrian War.<ref>[[Polybius]] 5.107.1–3</ref> [[Günther Hölbl]] argues that the fact that the rebels attacked Egyptian temples suggests that it was "a rebellion of the lower classes inspired by social injustice," that had been exacerbated by the heavy taxation necessary to fund that war.<ref>{{harvnb|Hölbl|2001|pp=153–154}}</ref> In October or November 205 BC, the leader of the southern revolt captured the city of [[Thebes, Egypt|Thebes]] and had himself crowned [[Pharaoh]], taking the name Horwennefer, rendered in Greek sources as [[Hugronaphor]]. Despite Ptolemaic efforts to suppress his regime, Horwennefer would retain his independence for nearly twenty years, until finally captured in August 186 BC.<ref>{{harvnb|Hölbl|2001|pp=154–155}}</ref><ref>{{cite web |last1=Bennett |first1=Chris |title=Horwennefer / Ankhwennefer|url=http://instonebrewer.com/TyndaleSites/Egypt/ptolemies/horwennefer.htm|website=Egyptian Royal Genealogy |access-date=29 October 2019}}</ref>

The revolt meant that Ptolemaic forces were unable to defend southern Egypt from [[Nubia]]n incursions. Probably in 207–06 BC, King [[Arqamani]] of [[Meroe]] seized control of the [[Dodecaschoenus]]. A number of the temple building projects that had been undertaken in this region were completed by Arqameni or his successor [[Adikhalamani]]. In many cases, the work of Ptolemy IV was simply appropriated by erasing his name from inscriptions and replacing it with that of Arqameni.<ref name="H16971"/>

In the midst of this conflict, in July or August 204 BC, Ptolemy IV died in unclear circumstances. A late source, [[John of Antioch (chronicler)|John of Antioch]] mentions a fire in the palace. Arsinoe III also died at this time. According to [[Justin (historian)|Justin]], she had been divorced and murdered by Ptolemy IV under the influence of his mistress Agathoclea, shortly before his own death. According to [[Polybius]], she was murdered by Sosibius. After a few days during which Ptolemy IV's death was kept secret, his six-year-old son [[Ptolemy V]], who had been co-regent since 210 BC, was formally proclaimed king with Sosibius and Agathoclea's brother Agathocles as his regents.<ref>[[Polybius]] 15.25–26a; [[Justin (historian)|Justin]], ''Epitome of Pompeius Trogus'' 30.2; John of Antioch ''[[FGrH]]'' 558 F54</ref><ref name=CBP4/><ref name=H133/>
