"the people of Nephi did seek diligently to restore the Lamanites unto the true faith in God. But our labors were vain; their hatred was fixed, and they were led by their evil nature that they became wild, and ferocious, and a blood-thirsty people, full of idolatry and filthiness; feeding upon beasts of prey; dwelling in tents, and wandering about in the wilderness with a short skin girdle about their loins and their heads shaven; and their skill was in the bow, and in the cimeter, and the ax. And many of them did eat nothing save it was raw meat; and they were continually seeking to destroy us"(Enos 1: 20).
Later on, a group of apostate and estranged priests led by a man named Amulon steal Lamanite daughters for wives. Years later, the Laminites discover the priests and but instead of punishing them for their crimes, they set them up as teachers. The Book of Mormon reads:
"And [King Laman] appointed teachers of the brethren of Amulon in every land which was possessed by his people; and thus the language of Nephi began to be taught among all the people of the Lamanites. And they were a people friendly one with another; nevertheless they knew not God; neither did the brethren of Amulon teach them anything concerning the Lord their God, neither the law of Moses; nor did they teach them the words of Abinadi; But they taught them that they should keep their record, and that they might write one to another. And thus the Lamanites began to increase in riches, and began to trade one with another and wax great, and began to be a cunning and a wise people, as to the wisdom of the world, yea, a very cunning people, delighting in all manner of wickedness and plunder, except it were among their own brethren" (Mosiah 24: 4).
Unknowingly, Amulon assisted in the eventual conversion of the Lamanites. By teaching the Lamanites to read the write the Nephite language they learned to read the language in which the scriptures were writen in. By teaching the Lamanites economic practices, they develped a degree of civility. After the conversion of the Lamanites by Alma the Younger and the sons of Mosiah, the Book of Mormon describes the Lamanites in a different light, “And they began to be a very industrious people; yea, and they were friendly with the Nephites; therefore, they did open a correspondence with them, and the curse of God did no more follow them” (Alma 23: 18).
Free trade practices also assisted in the conversion process of the Lamanites. The leader of the Anti-Nephi-Lehi's declared, "I thank my great God that he has given us a portion of his Spirit to soften our hearts, that we have opened a correspondence with these brethren, the Nephites. And behold, I also thank my God, that by opening this correspondence we have been convinced of our sins, and of the many murders which we have committed” (Alma 24: 8-9).
Later, after years of war, missionary work and free trade helped establish peace thoughtout the land.
“The people of the church did have great joy because of the conversion of the Lamanites, yea, because of the church of God, which had been established among them. And they did fellowship one with another, and did rejoice one with another, and did have great joy. And it came to pass that the Lamanites did also go whithersoever they would, whether it were among the Lamanites or among the Nephites; and thus they did have free intercourse one with another, to buy and to sell, and to get gain, according to their desire” (Hel. 6: 3-8).
