Colony of Queensland in the context of "Federation of Australia"

The history of socialism has its origins in the Age of Enlightenment and the 1789 French Revolution, along with the changes that brought, although it has precedents in earlier movements and ideas. The Communist Manifesto was written by Karl Marx and Friedrich Engels in 1847-1848 just before the Revolutions of 1848 swept Europe, expressing what they termed scientific socialism. In the last third of the 19th century parties dedicated to democratic socialism arose in Europe, drawing mainly from Marxism. The Australian Labor Party was the first elected socialist party when it formed government in the Colony of Queensland for a week in 1899.

In the first half of the 20th century, the Soviet Union and the communist parties of the Third International around the world, came to represent socialism in terms of the Soviet model of economic development and the creation of centrally planned economies directed by a state that owns all the means of production, although other trends condemned what they saw as the lack of democracy. The establishment of the People's Republic of China in 1949, saw socialism introduced. China experienced land redistribution and the Anti-Rightist Movement, followed by the disastrous Great Leap Forward. In the UK, Herbert Morrison said that "socialism is what the Labour government does" whereas Aneurin Bevan argued socialism requires that the "main streams of economic activity are brought under public direction", with an economic plan and workers' democracy. Some argued that capitalism had been abolished. Socialist governments established the mixed economy with partial nationalisations and social welfare.

The Territory of Papua comprised the southeastern quarter of the island of New Guinea from 1883 to 1975. In 1883, the Government of Queensland annexed this territory for the British Empire. The United Kingdom Government refused to ratify the annexation but in 1884 a protectorate was proclaimed over the territory, then called British New Guinea. There is a certain ambiguity about the exact date on which the entire territory was annexed by the British. The Papua Act 1905 recites that this happened "on or about" 4 September 1888. On 18 March 1902, the Territory was placed under the authority of the Commonwealth of Australia. Resolutions of acceptance were passed by the Commonwealth Parliament, which accepted the territory under the name of Papua.

In 1949, the Territory and the Territory of New Guinea were established in an administrative union by the name of the Territory of Papua and New Guinea. That administrative union was renamed as Papua New Guinea in 1971. Notwithstanding that it was part of an administrative union, the Territory of Papua at all times retained a distinct legal status and identity; it was a Possession of the Crown, whereas the Territory of New Guinea was initially a League of Nations mandate territory and subsequently a United Nations trust territory. This legal and political distinction remained until the advent of the Independent State of Papua New Guinea in 1975.

The Separation of Queensland was an event in 1859 in which the land that forms the present-day state of Queensland in Australia was excised from the Colony of New South Wales and proclaimed as a separate crown colony.

Q150 was the sesquicentenary (150th anniversary) of the Separation of Queensland from New South Wales in 1859. Separation established the Colony of Queensland which became the State of Queensland in 1901 as part of the Federation of Australia. Q150 was celebrated in 2009.

The first colonies of the British Empire on the continent of Australia were the penal colony of New South Wales, founded in 1788, and the Swan River Colony (later renamed Western Australia), founded in 1829. Over the next few decades, the colonies of New Zealand, Queensland, South Australia, Van Diemen's Land (later renamed Tasmania), and Victoria were created from New South Wales, as well as an aborted Colony of North Australia. On 1 January 1901, these colonies, excepting New Zealand, became states in the Commonwealth of Australia. Since federation, the internal borders have remained mostly stable, except for the creation of some territories with limited self-government: the Northern Territory from South Australia, to govern the vast, sparsely populated centre of the country; the split of the Northern Territory into Central Australia and North Australia, and then the quick merger of those back into the Northern Territory; and the Australian Capital Territory, a federal district ceded from New South Wales.

Outside of the continent, Queensland attempted an expansion into New Guinea, but British authorities rejected this; the claim would later be made a British protectorate and ceded to Australia. The League of Nations mandated northeast New Guinea to Australia after World War I, as well as Nauru, which was placed under joint Australian-British-New Zealand jurisdiction. These mandates (and, later, United Nations trust territories) became the independent nations of Nauru and Papua New Guinea in the mid-20th century. Australia has also obtained several small island territories, mainly from earlier British colonies, and has a large claim on Antarctica.
