Victoria (Australia) in the area occurred in 1803 at Sullivan Bay, and much of what is now Victoria was included in 1836 in the Port Phillip District, an administrative division of New South Wales. Named in honour of Queen Victoria, who signed the division's separation from New South Wales, the colony was officially established in 1851 and achieved self government in 1855. The Victorian gold rush in the 1850s and 1860s significantly increased both the population and wealth of the colony, and by the time of the Federation of Australia in 1901, Melbourne had become the largest city and leading financial centre
Capital city meaning "head". In several English-speaking states, the terms county town and county seat are also used in lower subdivisions. In some unitary states, subnational capitals may be known as "administrative centres". The capital is often the largest city of its constituent, though not always. Historically, the major economic centre of a state or region often becomes the focal point of political power, and becomes a capital through conquest or federation. (The modern capital city has, however, not always existed: in medieval Western Europe, an itinerant (wandering) government was common.) Examples are Ancient Babylon, Abbasid Baghdad, Ancient Athens, Rome, Constantinople, Chang'an,
