Which should I look at first, 1883 or 1923?

You can look at 1883 or 1923 first because they are independent. 1883 is a prequel to the American drama Yellowstone. The story focuses on the journey of the Duttons to the west many years ago. They crossed the Great Plains and came to the last wilderness of America, seeking a better future in the promised land of Montana. 1923 is a new play by Yellowstone National Park, which tells the story of how John Dutton's father James Dutton founded the Dutton family in 1923.
