Pelias
According to ancient Greek mythology Aeson was the rightful king of Iolcos, but his half-brother Pelias usurped the throne. It was Pelias who sent Aeson's son Jason and his Argonauts to look for the Golden Fleece.
Jason's father, Aeson, was the rightful king of Iolcos. His brother, Pelias, was power-hungry, though, and wanted to rule the entire region of Thessaly. So, Pelias killed his brother and as many of his descendants as he could find. Jason's mother saved him from this fate. Many years later, Jason traveled to Iolcos to claim his throne, but on the way, encountered Hera, disguised as an old woman trying to cross a river. Jason helped her across (it wasn't easy), so the woman blessed him (since she was Hera, she knew that Pelias would try to kill Jason). IN the crossing, Jason lost one of his sandals, so when he arrived in Iolcos for the games, he was announced simply as "the man with one sandal". Pelias, many years earlier, had been warned by an oracle that a man with one sandal would try to take his throne, so he accepted Jason into his home and announced that Jason could have his throne only if he could successfully return to Iolcos with the Golden Fleece of Colchis.
Jason was the son of Aeson, the King of Thessaly. Aeson's half-brother, Pelias, overthrew him and slew all of Aeson's children and family. Jason only survived because his mother Alcimede, made it appear that Jason was still born. Jason was taken to Chiron the centaur to be educated. Meanwhile, Pelias, ever fearful of being cast down by a rightful ruler, as most usurpers are, consulted an oracle who bade him to beware a man wearing one sandal. Many years later, Jason traveled to Iolcus to confront Pelias, and on the way lost a sandal in the river Anauros while helping an old woman cross. The old woman was Hera in disguise and she blessed Jason for his efforts. Once in the city, Pelias recognized Jason as the man from the prophecy and put forth as task that he hoped Jason would never return from: to retrieve the Golden Fleece from Colchis.
The uncle of Jason was Pelias.
He and his Argonauts recovered the Golden Fleece from Colchis and brought it back to king Pelias in the city of Iolcus (with a lot of help from Medea, a Colchian princess who had fallen in love with Jason).
A feud of kingship between a rightful son of the overthrown king (Jason son of Aeson) and Pelias (Aeson's half-brother; son of the god Poseidon).
It was Pelias, whose throne Jason wanted.
When Jason and Medea returned to Lolcus, they found out that Pelias had killed Jason's father and his mother had died later on due to mourning. - Morgahn Mulholland
