The Nephite contemporaries of M. were: Alma II (who disappeared the same year, 73 B. C., that M. was promoted to chief commander), Helaman, Teancum, Lehi and Pahoran. The Lamanite generals who were contemporary with M. and fought against him were: Zarahemna, Amalickiah, Ammoron, respectively. The Nephite rebels or usurpers who were contemporary with M. were: Amalickiah (who became Lamanite king and general), and Pachus who led the "kingmen."
The boundary dispute between the peoples of Lehi and Morianton (67 B. C.) was settled by M., as an intestinal vexation. Under M's. command Zarahemla was defeated and the Lamanites signally repulsed (73 B. C.) on the banks of the Sidon (Al. chap. xx); Amalickiah was frustrated in his attempt to become king and was defeated in his first invasion (which he did not attend in person) of the western possession of the Nephites, 72 B. C., Al. chap. xxi; Amalickiah was defeated and slain in his second invasion of the Nephites, in their rightful east-coastal possessions, 66 B. C., Al. chap., xxiii; Ammoron was slain and the Lamanites defeated and driven out of the land, 65-61 B. C., chapters xxiv-xxix, Moroni's fortifications and defences were prepared "in a manner which never had been known among the children of Lehi," Al. xxi:149-158.
Mosiah was the last king over the Nephites. Prior to his death he proclaimed in favor of a republican government which received the sanction of his people. This new order, the Judges, took effect after his demise with Alma II as first Chief Judge. Mosiah was custodian of the sacred records which he received from his father, King Benjamin, and committed them to Alma II. Mosiah i-xii.
