Easterns are related to Westerns, set in the same time period of roughly 1865-1900, but in the eastern and more urban part of America. In this regard they're almost mirror images of each other, with Easterns focusing on cities, civilization, and society rather than wilderness. Subgenres include soap opera, comedy of manners, legal/crime drama, and the hugely popular Boston marriage centering on a lesbian or queerplatonic relationship. Although Westerns tend to be dominated by men, Easterns feature far more women. Another interesting aspect is the color psychology. Whereas most Westerns use a warm palette, most Easterns use a cool palette.

One famous television series and its related movie stretch the time period, as Westerns sometimes do, such that they are considered Easterns even though they take place in the early 1800s. The television show The Other Mrs. Jefferson and the movie The Second Lady both feature the relationship between Thomas Jefferson and Sally Hemings. They first came out in 1935, then were remade in 1961, 1990, and 2014. The interpretations have varied somewhat as understanding of that relationship continues to evolve.
