Historical lies

I’m looking to make a list of ten or fifteen historical lies, things that conventional wisdom holds to be obviously true, but upon research and analysis can be conclusively shown to be false. Four obvious ones are:

1. The Spanish Inquisition was an evil institution comparable to the Final Solution or the Black Death.

2. Abraham Lincoln was dedicated to human liberty and fought the Civil War to free the slaves.

3. Religion is the primary cause of most of the wars in human history.

4. Islam is a religion of peace.

I’d like to hear your thoughts on the matter. No cows are sacred; if there’s any examples beloved of the Left, I’d like to hear them too.
