Revelation given through Joseph Smith the Prophet, at Nauvoo, Illinois, March 1841, concerning the Saints in the territory of Iowa.

1–4, The Saints are to build cities and to gather to the stakes of Zion.

1 What is the will of the Lord concerning the saints in the Territory of Iowa?
Note: The will of God is for everyone to sincerely believe in Jesus Christ.
“And this is the will of Him who sent Me, that everyone who sees the Son and believes in Him may have everlasting life; and I will raise him up at the last day.” John 6:40

2 Verily, thus saith the Lord, I say unto you, if those who call themselves by my name and are essaying to be my saints, if they will do my will and keep my commandments concerning them, let them gather themselves together unto the places which I shall appoint unto them by my servant Joseph, and build up cities unto my name, that they may be prepared for that which is in store for a time to come. 3 Let them build up a city unto my name upon the land opposite the city of Nauvoo and let the name of Zarahemla be named upon it.
Note: Joseph Smith tried to recreate a fictional Book of Mormon area.
Zarahemla is described as being near the mouth of a prominent river which the Book of Mormon calls the Sidon River and this river is described as flowing northward into the sea. The book further describes Zarahemla as being south of the Land of Bountiful and immediately south of a "narrow neck of land" that separates the southern land (which includes Zarahemla) from a northern land. Zarahemla is described as being north of the Land of Nephi and the Land of Nephi is described as being north of the Land of First Inheritance. Narrow "strips of wilderness" are described as surrounding Zarahemla on the west, east and south of the River Sidon. The Book of Mormon claims Zarahemla has significant ore deposits full of gold, silver, and copper.

4 And let all those who come from the east, and the west, and the north, and the south, that have desires to dwell therein, take up their inheritance in the same, as well as in the city of Nashville, or in the city of Nauvoo, and in all the stakes which I have appointed, saith the Lord.
Note: Joseph Smith was a false prophet.
Dissolution: In January 1842, the Zarahemla Stake was officially dissolved. Church leaders consolidated members in Nauvoo, Illinois, to help focus manpower on building the Nauvoo Temple and other community needs.
