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.

    I disagree that this is wrong, it’s up to the writer, but yes, it is not necessary. Apostrophes are not just for possession, but also for missing letters, or separating elements for clarity: such as a group of letter u’s, or separating a surname from the plural, such as the Johnson’s. It’s this last use that people apply to the year… I think the worst point is the waste of typing the ‘ in 1900’s.

      It’s up to the writer. Exactly. It’s also important to remember to pick one way of doing it and do it that way consistently throughout the work you are writing for.
