While Mormon colonization was planned and initiated under Brigham Young, he died before his planned settlements could be well established. Thus it remained for the Quorum of the Twelve and Brigham Young's successor, John Taylor, to save the settlements already established and to expand the colonization of Arizona. Thus Brigham Young's colonial plans and efforts should be discussed as a part of the story of Mormon colonization. In the last three years of his life the great Mormon leader planned a magnificent colonization.
