The 2021 film "The World to Come" takes place in which century?

The 2020 film "The World to Come", an American drama, was directed by Mona Fastvold, from a screenplay by Ron Hansen and Jim Shepard, based upon Shepard's story "The World to Come". It was produced by Pamela Koffler, David Hinojosa, Casey Affleck, Whitaker Lader, and Margarethe Baillou. It stars Katherine Waterston, Vanessa Kirby, Christopher Abbott, and Casey Affleck, and follows two neighboring couples battling hardship and isolation in 19th century America.

The movie keenly focuses on facts that somewhere in 1856 in Schoharie County, New York, along the American East Coast frontier, two farmers' wives (Abigail and Tallie) find themselves irrevocably drawn to each other.

Several film critics ultimately noted, "This film’s world is bizarrely insular and indistinct, forcing the audience to fill in all the blanks about these women’s everyday hardships beyond their husbands. Meanwhile, Affleck as Dyer and Abbott as Finney deserve some acclaim here for registering fairly memorable performances despite being given nothing but paint-by-numbers traits."
