History
Kiley 279 had long been divided into two factions, whose mutual animosity had nearly escalated to the point of global civil war by the mid-23rd century. In 2259, Starfleet detected a warp signature from the planet and sent the  to investigate. Its crew of three, led by Commander Una Chin-Riley, beamed down to make first contact but were imprisoned by the Kiley. 

The  subsequently arrived at Kiley 259 to find the Archer abandoned in orbit and no evidence of warp-capable civilization on the surface. A disguised landing party, led by Captain Christopher Pike, rescued the Archers crew and learned that the warp signature had in fact originated from a warp bomb, constructed by the Kiley after they observed the battle against Control a year earlier.

Given the Federation's inadvertent contribution to the looming crisis on the planet. Pike elected to disregard General Order 1 and reveal themselves so as to broker peace between the factions. He showed the Kiley leaders and population visual records of the devastation suffered by Earth during World War III, and urged them to avoid a similar fate and join the Federation instead. The Kiley thus decided to put aside their differences and pursue space travel as a united people. ()
