Herod the Great had no family tree to back up this claim. He wasn’t descended from David. He wasn’t even fully Jewish, being half Idumaean. But he married into the (then) royal family, taking as one of his many wives Mariamne, a princess from the Hasmonean house. And he maintained his rule—no mean feat in itself—for over thirty years. Judah the Hammer managed seven years; Simon the Star, only three.
