Xin rescued him. Or his father. Something like that.

Here it is.

"Jarvan II, hearing of this unprecedented feat, infiltrated the arena to offer him an alternative: serve Demacia and punish those who ultimately sentenced him to death in exchange for his freedom. Xin Zhao accepted, astonished that a king would risk his own life on his behalf. Under the cover of a prearranged Demacian assault on Noxus, Jarvan liberated Xin Zhao and his 300 opponents. During their retreat, Xin Zhao took a poisoned dart meant for Jarvan. This act of loyalty, from a man who vowed no allegiance, earned Xin Zhao a spot at his side until the day the king died."

Taken from Xin's lore. he's pretty much older than Garen I'd say. Since he was rescued by his grandfather.
