Helaman 11:23

And in the seventy and ninth year, there began to be much strife. But it came to pass that Nephi and Lehi, and many of their brethren, which knew concerning the true points of doctrine, having many revelations daily, therefore they did preach unto the people, insomuch that they did put an end to their strife in that same year.

In the seventy-ninth year, much fighting started. But Nephi and Lehi knew the true teachings. So did many of their brothers. They received messages from God every day. So they preached to the people. They stopped the fighting that same year.
