The first set of sacrifices (half of the Ancients / Amaurotines) were made to create / summon Zodiark.
The second set of sacrifices (half of those remaining, or 25% of the original population that survived the Sound) were made to rehabilitate the planet, which had been rendered inhospitable (if not uninhabitable) by the chaos created by the Sound.
The third set of (intended) sacrifices (some measure of "planetary life energy," most likely mortals) were set to resurrect that 75% of the Ancients that were sacrificed to Zodiark.
I don't think it's so much as the Ancients bribed him, so much as he needs energy (aether) to do things as all primals do, and the scale on which Zodiark operates far exceeds the primals summoned in contemporary times. According to Emet-Selch he had to "rewrite the laws of reality" as they pertained to the planet, and fixing the planet afterwards would also be no mean feat. The Ancients "fed" him, for lack of a better term, so that Zodiark could do the things they wanted him to do. Despite being "the will of the star," he's still beholden to the wishes and vision of his summoners.
It was when some number of other Ancients grew tired of the sacrifices to Zodiark that they broke off and started the conflict that ended with Hydaelyn sundering and imprisoning Zodiark, shattering the planet into its now-familiar Source and reflections. And that, as they say, is that.
