Russell C. Means, the charismatic Oglala Sioux who helped revive the warrior image of the American Indian in the 1970s with guerrilla-tactic protests that called attention to the nation’s history of injustices against its indigenous peoples, died on Monday at his ranch in Porcupine, S.D., on the Pine Ridge Indian Reservation. He was 72.

The cause was esophageal cancer, which had spread recently to his tongue, lymph nodes and lungs, said Glenn Morris, Mr. Means’s legal representative. Told in the summer of 2011 that the cancer was inoperable, Mr. Means had already resolved to shun mainstream medical treatments in favor of herbal and other native remedies.

Strapping, and ruggedly handsome in buckskins, with a scarred face, piercing dark eyes and raven braids that dangled to the waist, Mr. Means was, by his own account, a magnet for trouble — addicted to drugs and alcohol in his early years and later arrested repeatedly in violent clashes with rivals and the law. He was tried for abetting a murder, shot several times, stabbed once and imprisoned for a year for rioting.

He styled himself a throwback to ancestors who resisted the westward expansion of the American frontier. With theatrical protests that brought national attention to poverty and discrimination suffered by his people, he became arguably the nation’s best-known Indian since Sitting Bull and Crazy Horse.
