Because of Capella IV's strategic location along the Klingon-Federation border, both sides have made engroves on the planet. After the Federation made contact, Starfleet Medical sent a medical relief mission to the planet in 2264, but that was a failure.
In 2267, Teer Akaar was killed by his rival Maab with Klingon help. However, it was with the effort of Captain James T. Kirk and the crew of the USS Enterprise that the Klingons plan to subvert the planet failed.
In 2272, a coup engineered by a man named Keel forced the young ruler and his mother into off-world exile. Despite their exile, Eleen financed the construction of the huge monument known as the Tomb of Leonard James Akaar (Built while he was still alive, in accordance with Capellan tradition) on Capella IV, in order to let everyone know who had the rightful claim on the planetary throne.
