Ether 10:9

And it came to pass after the space of many years, Morianton, (he being a descendant of Riplakish) gathered together an army of outcasts, and went forth and gave battle unto the people; and he gained power over many cities; and the war became exceedingly sore, and did last for the space of many years; and he did gain power over all the land, and did establish himself king over all the land.
