Why Sauron wants the Ring?

He also laid the Groundwork and Foundation of his Third Age Rule in the Second Age (when he had the Ring).

Keep in mind also that at least in the case of the Easterlings, they had been allied with Morgoth since the First Age battles, and would have no doubt at least known of Sauron's status as his second-in-command. After Morgoth's fall, it wouldn't have been difficult for Sauron to have assumed the position of their overlord, especially if he promised to help them defeat and plunder the West, which they hated.
