History of Sydney
With the inauguration of the Commonwealth of Australia on 1 January 1901, Sydney ceased to be a colonial capital and became the capital of the Australian state of New South Wales. With industrialisation, Sydney expanded rapidly, and by the early 20th century it had a population well in excess of one million.

New South Wales was founded as a British colony in Sydney in 1788. Other colonies split away from New South Wales or were separately established over the Australian continent in the ensuing decades. The colonies became self-governing during the second half of the 19th century, starting with Victoria in 1852, although well before this time, all of the colonies had non-elected Legislative Councils to advise their respective Governors on matters of administration.
