The books from First Nephi to Omni are described as being from "the small plates of Nephi". This account begins in ancient Jerusalem around 600 BC. It tells the story of a man named Lehi, his family, and several others as they are led by God from Jerusalem shortly before the fall of that city to the Babylonians in 586 BC. The book describes their journey across the Arabian peninsula, and then to the "promised land", the Americas, by ship. These books recount the group's dealings from approximately 600 BC to about 130 BC, during which time the community grew and split into two main groups, which are called the Nephites and the Lamanites, that frequently warred with each other.
