What are some of the biggest historical misconceptions that you can think of?
Personally, for me, one of them would be that Abraham Lincoln went to war to end slavery. No, he didn't:
Another misconception is that James Garfield's doctors killed him and that Charles Guiteau simply shot him. In reality, this relatively recent (2013) article by two doctors makes a rather convincing case that Garfield was suffering from cholecystitis (an inflammation of the gallbladder, with it subsequently rupturing) as a result of being shot and that he died as a result of the rupture of the pseudoaneurysm that developed in his splenic artery as a result of him getting shot:
This article also makes an excellent case that if his splenic artery pseudoaneurysm would not have ruptured, Garfield's cholecystitis would have very likely killed him since the first successful gallbladder removal was only performed a year after Garfield's death, and this would be assuming that Garfield's doctors would actually figure out that Garfield was suffering from cholecystitis, which is probably unlikely.

Since the Civil War did end slavery, many Americans think abolition was the Union’s goal. But the North initially went to war to hold the nation together. Abolition came later.
On Aug. 22, 1862, President Lincoln wrote a letter to the New York Tribune that included the following passage: “If I could save the Union without freeing any slave, I would do it; and if I could save it by freeing all the slaves, I would do it; and if I could save it by freeing some and leaving others alone, I would also do that. What I do about slavery and the colored race, I do because I believe it helps to save the Union; and what I forbear, I forbear because I do not believe it would help to save the Union.”
However, Lincoln’s own anti-slavery sentiment was widely known at the time. In the same letter, he went on: “I have here stated my purpose according to my view of official duty; and I intend no modification of my oft-expressed personal wish that all men every where could be free.” A month later, Lincoln combined official duty and private wish in his preliminary Emancipation Proclamation.
White Northerners’ fear of freed slaves moving north then caused Republicans to lose the Midwest in the congressional elections of November 1862.
Gradually, as Union soldiers found help from black civilians in the South and black recruits impressed white units with their bravery, many soldiers — and those they wrote home to — became abolitionists. By 1864, when Maryland voted to end slavery, soldiers’ and sailors’ votes made the difference.
