The Yellowstone timeline spans over a century, exploring the founding and rise of the Yellowstone Dutton Ranch. The spinoff series, 1883, reveals the ranch's founding, while 1923 depicts how the Duttons kept the ranch running during a difficult economic period. The shared Yellowstone universe connects key events in the Dutton family history to contemporary events in America's development. There are plans for additional spinoffs set before and after Yellowstone. Rumored spinoffs include one set in 1944 and another in the 1960s. The modern Yellowstone timeline follows the Duttons' struggles and conflicts on the ranch, with season 5 introducing a new spinoff called 6666.
