Background: This issue of Niles’ National Register from October 13, 1838, serves as a crucial primary source capturing the immediate escalation of the 1838 Missouri Mormon War just weeks before Governor Lilburn Boggs issued the Extermination Order on October 27. The reporting highlights the underlying economic and territorial drivers of the conflict, directly attributing the hostility to local non-Mormon desire to seize rich farms and prevent Latter Day Saint settlement on prime fine lands across Carroll, Davies, and Caldwell counties. By documenting the testimony of a committee addressed "To the citizens of Chariton," alongside the legal appearances of Joseph Smith and Lyman Wight before Judge King, the publication records the desperate and failing attempts at judicial intervention as Saints were left begging for peace. Featuring authentic printed letters signed in type by Joseph Smith, Jr. and Sidney Rigdon, this 16-page Baltimore periodical provided the American public with an unfiltered, real-time look into frontier religious persecution, land speculation, and the rapid breakdown of law and order that ultimately led to the mass expulsion of Mormons from Missouri.

As noted in Wikipedia, this title: "...(was) one of the most widely-circulated magazines in the United States...Devoted primarily to politics...considered an important source for the history of the period."
