Bareknuckle boxing is quite different.
There are less punches thrown as the head elbows can be used to break the opponents fist.
And obviously, bare fists do more damage, and can cut the face more. So the movements of the fight were slower, with less snappy punches and jabs.
Gloves were apparently added to make the sport more exciting since it would be faster with more pucnhes, but actually led to far more hits to the head and the chances of more serious damage.
