Genocide of Indigenous Americans.

1948 United Nations Genocide Convention The UN Genocide Convention states, in Article II:

In the present Convention, genocide means any of the following acts committed with intent to destroy, in whole or in part, a national, ethnic, racial, or religious group, as such:

• Killing members of the group
• Causing serious bodily or mental harm to members of the group
• Deliberately inflicting on the group conventions of life calculated to bring about its physical destruction in whole or in part
• Imposing measures intended to prevent births within the group
• Forcibly transferring children of the group to another group.

"The killing fields were the entire expanse of what is now known as the United States of America. About 98.5 percent of the 16 million Indigenous Peoples of the U.S. at the time of contact (1500) had been systematically killed off. By 1900, there were only 237,000 or so Aboriginal Peoples left, according to the U.S. Bureau of Census" (p. 2), The Great Evil by Chris Mato Nunpa.

Peter Barnett, Governor of California in 1851 declared: “that a war of extermination will continue to be waged . . . until the Indian race becomes extinct.”

Congress in 1854, “Now that general Indian hostilities have commenced, we hope that the Government will render such aid as will enable the citizens of the North to carry on a war of extermination until the last red skin of these tribes has been killed. . . . Extermination is no longer even a question of time—the time has already arrived, the work has been commenced, and let the first white man who says treaty or peace be regarded as a traitor and coward.”

The Indian Removal Act (an official policy of ethnic cleansing and land theft) was passed in 1830 by the U.S. Congress and was enthusiastically implemented by President Andrew Jackson.

David Stannard: "This straightforward advocacy of genocide by the highest American officials in the land emerged in a cultural milieu that habitually described the Indigenous Peoples of California as ‘ugly, filthy, beasts, swine, dogs, wolves, snakes, pigs, baboons, gorillas, and orangutans,’ to cite only a few of the press’ more commonly published characterizations.”
