The union of the states
Most Southerners believed that states had freely been created and joined the Union and could freely leave the Union. President Lincoln and the North did not believe this.
The most immediate result of Abraham Lincoln's election to the presidency in 1860 was that many Southern states seceded from the Union. Abraham Lincoln was the 16th President of the United States.
The President of the United States gives a State of the Union Address so that we can sit and listen to all the things that he has done and is about to do, most of which we have no control over. HENCE, driving us all insane.

During the term of Benjamin Harrison (1889-1893), 6 states were admitted to the Union, more than under any other President. The states were North Dakota, South Dakota, Montana, Washington, Idaho, and Wyoming. The original 13 states were already part of the Union in 1789, so George Washington's two terms (1789-1797) saw only three "new" states, If the Confederate states were considered by "re-admission", Andrew Johnson (1865-1869) would have the most with 8 of the Southern states regaining representation in Congress.
The president most likely to support the secession of the Southern states from the Union would be John C. Calhoun, who served as Vice President and was a strong proponent of states' rights and nullification. While not a president himself, his political ideology aligned closely with the interests of Southern states seeking to secede. Among actual presidents, Andrew Johnson, who succeeded Abraham Lincoln, had a more lenient approach to Reconstruction and might have been more sympathetic to Southern grievances. However, it is important to note that no president openly supported secession, as it was a constitutional crisis.
