Adelaide is the capital and largest city of South Australia, with a population of approximately 1,368,209 inhabitants. Founded in 1836 and named after Queen Adelaide, consort of King William IV, the city was planned as a free settlement rather than a penal colony, which shaped its early social and political development. Designed by Colonel William Light, Adelaide is noted for its grid layout surrounded by parklands. During the nineteenth century it became a center of agriculture, wine production, and cultural life, earning a reputation as a progressive and well-planned city.

Today, Adelaide is known for its festivals, universities, and thriving arts scene. Major cultural institutions include the Art Gallery of South Australia, which houses significant Australian and international collections. The city also serves as a gateway to renowned wine regions such as the Barossa Valley. Notable individuals born in Adelaide include tennis champion Lleyton Hewitt and internationally acclaimed singer-songwriter Sia.
