Revelation and prophecy on war, given through Joseph Smith the Prophet, at or near Kirtland, Ohio, December 25, 1832. At this time disputes in the United States over slavery and South Carolina’s nullification of federal tariffs were prevalent. Joseph Smith’s history states that “appearances of troubles among the nations” were becoming “more visible” to the Prophet “than they had previously been since the Church began her journey out of the wilderness.”

1–4, War is foretold between the Northern States and the Southern States; 5–8, Great calamities will fall upon all the inhabitants of the earth.

1 Verily, thus saith the Lord concerning the wars that will shortly come to pass, beginning at the rebellion of South Carolina, which will eventually terminate in the death and misery of many souls; 2 And the time will come that war will be poured out upon all nations, beginning at this place.
Note: Joseph Smith was a false prophet.
No foreign nation officially entered the American Civil War as a combatant or formally recognized the Confederate States of America, though other countries were heavily involved through diplomacy, trade, and indirect support.

3 For behold, the Southern States shall be divided against the Northern States, and the Southern States will call on other nations, even the nation of Great Britain, as it is called, and they shall also call upon other nations, in order to defend themselves against other nations; and then war shall be poured out upon all nations.
Note: Joseph Smith was a false prophet.
Great Britain and France maintained official neutrality throughout the war and refused to grant official diplomatic recognition to the Confederacy, despite heavy pressure from the South's "King Cotton" diplomacy.

4 And it shall come to pass, after many days, slaves shall rise up against their masters, who shall be marshaled and disciplined for war. 5 And it shall come to pass also that the remnants who are left of the land will marshal themselves, and shall become exceedingly angry, and shall vex the Gentiles with a sore vexation. 6 And thus, with the sword and by bloodshed the inhabitants of the earth shall mourn; and with famine, and plague, and earthquake, and the thunder of heaven, and the fierce and vivid lightning also, shall the inhabitants of the earth be made to feel the wrath, and indignation, and chastening hand of an Almighty God, until the consumption decreed hath made a full end of all nations;

Global Trade: European nations traded with both sides for supplies like arms and manufactured goods, and Britain pivoted to importing cotton from India and Egypt while relying on Northern wheat.

7 That the cry of the saints, and of the blood of the saints, shall cease to come up into the ears of the Lord of Sabaoth, from the earth, to be avenged of their enemies. 8 Wherefore, stand ye in holy places, and be not moved, until the day of the Lord come; for behold, it cometh quickly, saith the Lord. Amen.
Note: Joseph Smith tried to capitalize on a current event.
In December 1832, Andrew Jackson released his Proclamation to the People of South Carolina, declaring that nullification was illegal and that "disunion by armed force is treason”.
Note: Merry Christmas!
