Yagan, a Noongar warrior wanted for leading attacks on British colonists in Western Australia, was killed, becoming a symbol of the unjust and sometimes brutal treatment of indigenous Australians by colonial settlers.

Yagan was an Aboriginal Australian warrior from the Noongar people. Yagan was pursued by the local authorities after he killed Erin Entwhistle, a servant of farmer Archibald Butler. It was an act of retaliation after Thomas Smedley, another of Butler's servants, shot at a group of Noongar people stealing potatoes and fowls, killing one of them. The government offered a bounty for Yagan's capture, dead or alive, and a young settler, William Keats, shot and killed him. Yagan is considered a legendary figure by the Noongar.

The Noongar are Aboriginal Australian people who live in the south-west corner of Western Australia, from Geraldton on the west coast to Esperance on the south coast. There are 14 different groups in the Noongar cultural bloc: Amangu, Ballardong, Yued, Kaneang, Koreng, Mineng, Njakinjaki, Njunga, Pibelmen, Pindjarup, Wadandi, Whadjuk, Wiilman and Wudjari. The Noongar people refer to their land as Noongar boodja.

Western Australia (WA) is the westernmost state of Australia. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a land area of 2,527,013 square kilometres (975,685 sq mi), and is also the second-largest subdivision of any country on Earth.

Indigenous Australians are people with familial heritage from, or recognised membership of, the various ethnic groups living within the territory of contemporary Australia prior to British colonisation. They consist of two distinct groups, which include many ethnic groups: the Aboriginal Australians of the mainland and many islands, including Tasmania, and the Torres Strait Islanders of the seas between Queensland and Papua New Guinea, located in Melanesia. 812,728 people self-identified as being of Aboriginal and/or Torres Strait Islander origin in the 2021 Australian Census, representing 3.2% of the total population of Australia. Of these Indigenous Australians, 91.4% identified as Aboriginal, 4.2% identified as Torres Strait Islander, and 4.4% identified with both groups.
