I've read enough about early days hockey to know it was much,
much worse circa 1890-1920.
Players pretty much used their sticks as swords on a fairly regular basis.

It really depends on how you define “dirty”.
Early era hockey was probably a LOT less physical than what we’re used to seeing. The fact that major injuries were rare — very few broken bones or head injuries in a given season — tells us that players
couldn’t have been experiencing high speed collisions or falling hard to the ice on a regular basis. The idea of “finishing your check” did not exist. Flying around the ice with your stick carelessly in the air did not exist. Cross-checking was an actual penalty that was actually called, and therefore wasn’t nearly as common as we see it today.
When I think about dirty play in today’s game, 90% of it has to do with late/high/blindside hits or stickwork. Meaning a very large chunk of what we currently complain about was rare or nonexistent in that era. And, when it did happen, it was remarkable enough to be reported on with a tone of disappointment. Today it’s just the way of things.
Which isn’t to say accidents didn’t happen or that players weren’t
occasionally reckless. What differentiates that era from today is the scale of retaliation that often resulted. If someone clipped you in the face with his stick, it wasn’t out of bounds to deliberately smack him over the back of the head in response. If you got jammed a bit too hard on the boards, you might skate up and sucker-punch the offender. If he felt the need for vigilante justice, he’d chase you into the penalty box and a cop would have to pull him off of you. This kind of stuff would be a generational incident in 2019, but it was just the way of things in 1919.
So... yes,
in a sense the game was more violent at that time. Minute-by-minute it probably was a calmer and more gentlemanly game. But the controls were much looser when emotion began to spill over.
