The term ketchup/catsup (or various other spellings) first appeared in about the 1600s, but tomato ketchup didn’t really catch on until about 200-300 years later. Before then it was used to refer to a variety of different sauces/condiments. Mushroom ketchup was a fairly popular one, some were based on fish sauces (you could maybe make an argument that Worcestershire sauce is a type of ketchup) etc.
The general consensus is that it was sort of the result Europeans attempting to recreate various Asian sauces without really knowing what was in them or having access to the right ingredients (for example trying to make something like soy sauce without soy beans)
My favourite story about all that was the one about Worcestershire Sauce … a bunch of English guys who had never been to India wanted to make their own fish sauce but it didn’t work out, so they stored their barrel of stuff in the basement and forgot about it … they found it a year later, tasted it and noticed that it didn’t kill them or make them sick, so they sold it as Lea & Perrins Worcestershire sauce
Ketchup has kind of an interesting history
