Shows like Yellowstone

If you want Yellowstone's brutal land wars and multigenerational power struggles, you're probably looking at 1923 (the prequel that literalizes the Dutton saga's origins), Legends of the Fall (same Montana wilderness, same masculine pride destroying families), or Horizon: An American Saga (sprawling settlement conflicts where survival corrodes loyalty). For the specific cattle-empire-under-siege tension, In Old Montana, Vengeance Valley, and Dutton Ranch lean harder on the ruthless tactics and rival factions, though they'll lack Yellowstone's modern corporate angles. Bonanza and the older Westerns offer the patriarch-led dynasty framework but trade moral complexity for clearer heroics, so your appetite for ambiguity matters here.
