Red & Black Beetles

I photographed these beetles today next to Manzanares Castle near Madrid, Spain. They were joined at the tails and I watched them moving for 10 minutes with no separation and one of them dragging the other.
What are they?
Was their joined tails a freak of nature or were they mating?
Many thanks.
