Has there ever been significant “deflation” in the world economy?

This is a question that I've started thinking about. admittedly, I'm not remotely a numbers person and I make no claims that I fully understand the concept of "inflation."

Obviously right now with tariffs, shipping routes, etc. affecting costs, there's a lot of outside factors that can cause inflation. But outside of this specific instance, has there ever been a notable moment of "deflation" in world history?

Like not a specific drop in one sector, like price drops in real estate or fuel or eggs or whatever, but an actual "across the board" drop in costs worldwide? I feel as though in my life I've only ever seen prices increase. I'm sure it's probably happening in much slower, harder to notice places but outside of gas prices that can fluctuate day-to-day, I don't feel as though I've seen costs drop in larger, noticeable ways.

Any help is appreciated! I am not a smart man and completely accepted that.
