Why does Ayers Rock have two names?

Uluru, also known as Ayers Rock, has had two names since British colonisation in the 1870s. The name "Ayers Rock" was given to the rock formation in 1873 by the explorer William Gosse, who named it after the then Chief Secretary of South Australia, Sir Henry Ayers. The Aboriginal name "Uluru" is believed to have originated from the Pitjantjatjara language, spoken by the Indigenous Australian peoples of the area, and is thought to mean "rock" or "meeting place". In 1993, the name of the rock formation was officially changed to "Uluru / Ayers Rock" to recognise its dual heritage and significance to both Aboriginal and non-Aboriginal Australians.
