Was the bubonic plague the Black Death? Some people say no.

That may be true, but it may also be less contagious or less easily transmitted between people.

Was the bubonic plague the Black Death? Some people say no.

Yes it was, the buboes (a symptom) caused the skin to turn black, hence the name "Black Death".

I think the pneumonic version was the most deadly, killing people in just a few hours. There are stories about victims looking healthy at breakfast but falling dead before suppertime. No wonder people thought it was the end of the world.
