This general area is the place where 'Ali's second son, Husayan, was massacred by the Umayyads on his way to Kufa. The people of Kufa were going to help him claim his right to the caliphate, but the Umayyads stopped and slaughtered him and his small band of family members and followers. The massacre would have happened around the west side of Karbala because they were heading to Kufa from the north west.(http://i-cias.com/e.o/husayn.htm)
