It’s 1900s, not 1900’s. You only use an apostrophe when you’re omitting the first two digits: ‘90s, not 90’s or ‘90’s.

Why YSK: It’s an incredibly common error and can detract from academic writing as it is factually incorrect punctuation.

    Once upon a time, apostrophes in these plurals were considered correct. If you aren’t using a particular style guide, it’s writer’s preference today.
