Nephites

Nephi takes those who will follow him and leaves to settle in the land of Nephi.
Now the people which were not Lamanites were Nephites; nevertheless, they were called Nephites, Jacobites, Josephites, Zoramites, Lamanites, Lemuelites, and Ishmaelites.
12) Behold, I am Amaleki, the son of Abinadom. Behold, I will speak unto you somewhat concerning Mosiah, who was made king over the land of Zarahemla; for behold, he being warned of the Lord that he should flee out of the land of Nephi, and as many as would hearken unto the voice of the Lord should also depart out of the land with him, into the wilderness—
13) And it came to pass that he did according as the Lord had commanded him. And they departed out of the land into the wilderness, as many as would hearken unto the voice of the Lord; and they were led by many preachings and prophesyings. And they were admonished continually by the word of God; and they were led by the power of his arm, through the wilderness until they came down into the land which is called the land of Zarahemla.
14) And they discovered a people, who were called the people of Zarahemla. Now, there was great rejoicing among the people of Zarahemla; and also Zarahemla did rejoice exceedingly, because the Lord had sent the people of Mosiah with the plates of brass which contained the record of the Jews.
15) Behold, it came to pass that Mosiah discovered that the people of Zarahemla came out from Jerusalem at the time that Zedekiah, king of Judah, was carried away captive into Babylon.
16) And they journeyed in the wilderness, and were brought by the hand of the Lord across the great waters, into the land where Mosiah discovered them; and they had dwelt there from that time forth.
17) And at the time that Mosiah discovered them, they had become exceedingly numerous. Nevertheless, they had had many wars and serious contentions, and had fallen by the sword from time to time; and their language had become corrupted; and they had brought no records with them; and they denied the being of their Creator; and Mosiah, nor the people of Mosiah, could understand them.
18) But it came to pass that Mosiah caused that they should be taught in his language. And it came to pass that after they were taught in the language of Mosiah, Zarahemla gave a genealogy of his fathers, according to his memory; and they are written, but not in these plates.
19) And it came to pass that the people of Zarahemla, and of Mosiah, did unite together; and Mosiah was appointed to be their king.
10) And these are the words: Behold, I perceive that this very people, the Nephites, according to the spirit of revelation which is in me, in four hundred years from the time that Jesus Christ shall manifest himself unto them, shall dwindle in unbelief.
11) Yea, and then shall they see wars and pestilences, yea, famines and bloodshed, even until the people of Nephi shall become extinct—
12) Yea, and this because they shall dwindle in unbelief and fall into the works of darkness, and lasciviousness, and all manner of iniquities; yea, I say unto you, that because they shall sin against so great light and knowledge, yea, I say unto you, that from that day, even the fourth generation shall not all pass away before this great iniquity shall come.
13) And when that great day cometh, behold, the time very soon cometh that those who are now, or the seed of those who are now numbered among the people of Nephi, shall no more be numbered among the people of Nephi.
14) But whosoever remaineth, and is not destroyed in that great and dreadful day, shall be numbered among the Lamanites, and shall become like unto them, all, save it be a few who shall be called the disciples of the Lord; and them shall the Lamanites pursue even until they shall become extinct. And now, because of iniquity, this prophecy shall be fulfilled.
Mormon negotiates a final battle between the Nephites and the Lamanites. The Nephites lose and only 24 survive aside from deserters.

Notes

The Lehites would have arrived around 591–589 B.C., and the Nephite civilization would have separated as a distinct population around 588–559 B.C., settling the Land of Nephi.

Mosiah would seem to have led a group of Nephites to Zarahemla, making this the new population center, (the civilization in the Land of Nephi being destroyed and replaced by Lamanites) and merging with the Mulekites, around 360 to 400 B.C.

The Nephite civilization is destroyed in one final battle with the Lamanites about A.D. 385.
