Gritty comes from grit ("small hard granules"), which in turn derives, via Middle English, from an Old English word for "sand" or "gravel." Grit has been around since before the 12th century, but the first appearance of gritty in print in English was near the end of the 16th century, when it was used in the sense of "resembling or containing small hard granules." Grit entered American slang with the meaning "courage or persistence" in the early 19th century, and gritty followed suit with a corresponding "plucky" sense. By the 19th century's end, gritty was also being used to describe a literary style that was rough and coarse.
