when was lonesome dove made

The original Lonesome Dove television miniseries was made and first aired in 1989.
It was broadcast in the United States on CBS over four nights from February 5 to 8, 1989, adapting Larry McMurtry’s 1985 novel into a four-part epic Western. This 1989 miniseries is what people usually mean when they ask “when was Lonesome Dove made,” even though later follow‑ups like Lonesome Dove: The Series (1994–1995) also exist.
