Aequi(redirected from Aequans)
an ancient Italian tribe, evidently of Osean descent. In the middle of the first millennium B.C. the Aequi settled in the Aniene Valley. From the early fifth century B.C., along with the Sabines, Volscians, and Hernicians, they waged a bitter struggle with the Romans, who finally subjugated the Aequi in 304 B.C.
