Hattusili III
Upon the death of Muwattalli II, Hattusili III's nephew Urhi-Teshub became king. There was controversy with this appointment, because Urhi-Teshub was the son of Muwattalli's concubine, not his wife. Despite his origins as a "second-rank son", Hattusili III initially supported Urhi-Teshub's kingship as it was the wish of Muwatalli II that Urhi-Teshub should rule. Urhi-Teshub ruled under the name Mursili III. Shortly after his accession to the throne, Mursili III had the capital moved from Tarhuntassa back to its original home of Hattussa. This effectively reduced much of Hattusili's power in the region and nullified his role as king of the northern territories. Hattusili III was also stripped of all of his territories aside from Hapkis and Nerik. This strained the relationship greatly, and upon having Nerik stripped of him as well, Hattusili III sought to usurp the throne.
