However, after the destruction of the First Commonwealth and the absence of the hegemony of an Israelite regime, the Moabites and Edomites discarded their affiliation to the people of Israel and left Judaism en masse. To bring them back into the fold, the Hasmonean leaders decided to re-convert them a second time. The mass Judaization campaign was started by John Hyrcanus with the conversion of the Moabites and was ended by Alexander Jannaeus who completed the conversion of the Moabites and also the Edomites after he added their territory to his Kingdom.
