The term "hate crime" was essentially nonexistent until the 1980's, and the first legislation to incorporate the term was passed in 1990. There are references to "hate crime" laws as far back as 1968, but they weren't called that at the time. They were redefined as such after the term came into use some 20-odd years later. "Hate crime laws" weren't an actual thing-- even simply in open discussion-- until the mid 80s/early 90s, with the major distinction being that crimes came with harsher penalties when they were prompted primarily by bigotry.

(EDIT) Fun fact: The Spanish Inquisition, that scourge of the Middle Ages with its torture chambers and burning of witches and Jews, wasn't officially ended until 1834.
