According to the Book of Mormon, Mulek (/ˈmjuː.lɛk/) was the only surviving son of Zedekiah, the last King of Judah, after the Babylonian conquest of Jerusalem. The Book of Mormon states that after escaping from Judah, Mulek traveled to the Americas and established a civilization there. Although the word Mulekites does not appear in the record, these people of Mulek are today commonly referred to simply as "Mulekites".
The Mulekites are one of four groups (including the Nephites, Lamanites, and Jaredites) described in the Book of Mormon as having settled in the ancient Americas. However, there is existence of the Mulekites and of the other three groups is not accepted by mainstream archaeology.
According to the Book of Mormon, when Jerusalem was destroyed by Babylon during the reign of Zedekiah, all of the sons of Zedekiah were killed except Mulek. Along with "as many as would hearken unto the voice of the Lord," Mulek escaped into the wilderness and traveled "across the great waters" to the Americas, founding a new nation. The people of Mulek established their capital at Zarahemla, north of where Lehi and his people landed.
Even though the word "Mulekite" or "Mulekites" /ˈmjuːlᵻˌkaɪts/ never occurs in the text of the Book of Mormon, the people of his nation are commonly called Mulekites by Latter Day Saints. This can be seen in certain chapter summaries of the Book of Mormon. In the text of the Book of Mormon, the Mulekites are referred to as the "people of Zarahemla".
