The history of Oceania includes the history of Australia, Easter Island, Fiji, Hawaii, New Zealand, Papua New Guinea, Western New Guinea, and other Pacific island nations.
Nauru, officially the Republic of Nauru and formerly known as Pleasant Island, is an island country and microstate in Micronesia, part of Oceania in the Central Pacific. Its nearest neighbour is Banaba of Kiribati, about 300 km (190 mi) to the east.
The history of human activity in Nauru, an island country in the Pacific Ocean, began roughly 3,000 years ago when clans settled the island.
German Samoa was a German protectorate from 1900 to 1920, consisting of the islands of Upolu, Savai'i, Apolima and Manono, now wholly within the Independent State of Samoa, formerly Western Samoa. Samoa was the last German colonial acquisition in the Pacific basin, received following the Tripartite Convention signed at Washington on 2 December 1899 with ratifications exchanged on 16 February 1900. It was the only German colony in the Pacific, aside from the Jiaozhou Bay Leased Territory in China, that was administered separately from German New Guinea.
German New Guinea consisted of the northeastern part of the island of New Guinea and several nearby island groups and was the first part of the German colonial empire. The mainland part of the territory, called Kaiser-Wilhelmsland, became a German protectorate in 1884. Other island groups were added subsequently. The Bismarck Archipelago, and the North Solomon Islands were declared a German protectorate in 1885. The Caroline Islands, Palau, and the Mariana Islands were bought from Spain in 1899. German New Guinea annexed the formerly separate German Protectorate of Marshall Islands, which also included Nauru, in 1906. German Samoa, though part of the German colonial empire, was not part of German New Guinea.
This is an overview of the postage stamps and postal history of Australia.
The Australian Naval and Military Expeditionary Force (AN&MEF) was a small volunteer force of approximately 2,000 men, raised in Australia shortly after the outbreak of World War I to seize and destroy German wireless stations in German New Guinea in the south-west Pacific. The German wireless installations were ordered to be destroyed because they were used by Vizeadmiral Maximilian von Spee's East Asia Squadron of the Imperial German Navy, which threatened merchant shipping in the region. Following the capture of German possessions in the region, the AN&MEF provided occupation forces for the duration of the war. New Zealand provided a similar force for the occupation of German Samoa.
The South Seas Mandate, officially the Mandate for the German Possessions in the Pacific Ocean Lying North of the Equator, was a League of Nations mandate in the "South Seas" given to the Empire of Japan by the League of Nations following World War I. The mandate consisted of islands in the north Pacific Ocean that had been part of German New Guinea within the German colonial empire until they were occupied by Japan during World War I. Japan governed the islands under the mandate as part of the Japanese colonial empire until World War II, when the United States captured the islands. The islands then became the United Nations–established Trust Territory of the Pacific Islands governed by the United States. The islands are now part of Palau, the Northern Mariana Islands, the Federated States of Micronesia, and the Marshall Islands.
The Territory of New Guinea was an Australian-administered United Nations trust territory on the island of New Guinea from 1914 until 1975. In 1949, the Territory and the Territory of Papua 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 New Guinea at all times retained a distinct legal status and identity until the advent of the Independent State of Papua New Guinea.
The states and territories are the second level of government of Australia. The states are administrative divisions that are self-governing polities that are partly sovereign, having ceded some sovereign rights to the federal government. They have their own constitutions, legislatures, executive governments, judiciaries and law enforcement agencies that administer and deliver public policies and programs. Territories can be autonomous and administer local policies and programs much like the states in practice, but are still legally subordinate to the federal government.
The Territory of Papua and New Guinea, officially the Administrative Union of the Territory of Papua and the Territory of New Guinea, was established by an administrative union between the Australian-administered territories of Papua and New Guinea in 1949. In December 1971, the name of the Territory changed to "Papua New Guinea" and in 1975 it became the Independent State of Papua New Guinea.
The Battle of Bita Paka was fought south of Kabakaul, on the island of New Britain, and was a part of the invasion and subsequent occupation of German New Guinea by the Australian Naval and Military Expeditionary Force (AN&MEF) shortly after the outbreak of the First World War. Similar to New Zealand's operation against German Samoa in August, the main target of the operation was a strategically important wireless station—one of several used by the German East Asia Squadron—which the Australians believed to be located in the area. The powerful German naval fleet threatened British interests and its elimination was an early priority of the British and Australian governments during the war.
Samoan nationality law is regulated by the 1962 Constitution of Samoa, as amended; the Citizenship Act 2004, and its revisions; the Citizenship Investment Act 2015; and international agreements entered into by the Samoan government. These laws determine who is, or is eligible to be, a national of Samoa. The legal means to acquire nationality, formal legal membership in a nation, differ from the domestic relationship of rights and obligations between a national and the nation, known as citizenship. Samoan nationality is typically obtained either on the principle of jus soli or under the rules of jus sanguinis. It can be granted to persons who have lived in the country for a specific period of time, who have contributed to the country's development, or who have an affiliation to the country through naturalisation.
The Occupation of Samoa was the takeover – and subsequent administration – of the Pacific colony of German Samoa by New Zealand during World War I. It started in late August 1914 with landings by the Samoa Expeditionary Force from New Zealand. The landings were unopposed and the New Zealanders took possession of Samoa for the New Zealand Government on behalf of King George V. The Samoa Expeditionary Force remained in the country until 1915, while its commander, Colonel Robert Logan, continued to administer Samoa on behalf of the New Zealand Government until 1919. The takeover of Samoa was New Zealand's first military action in World War I.
The postage stamps and postal history of Papua New Guinea originated in the two colonial administrations on the eastern part of the island of New Guinea and continued until their eventual merger, followed by independence in 1975.
The decolonisation of Oceania occurred after World War II when nations in Oceania achieved independence by transitioning from European colonial rule to full independence.
The Japanese occupation of Nauru was the period of three years during which Nauru, a Pacific island which at that time was under Australian administration, was occupied by the Japanese military as part of its operations in the Pacific War during World War II. With the onset of the war, the islands that flanked Japan's South Seas possessions became of vital concern to Japanese Imperial General Headquarters, and in particular to the Imperial Navy, which was tasked with protecting Japan's outlying Pacific territories.
The Australian occupation of German New Guinea was the takeover of the Pacific colony of German New Guinea in September – November 1914 by an expeditionary force from Australia, called the Australian Naval and Military Expeditionary Force.
The Japanese occupation of the Gilbert Islands was the period in the history of Kiribati between 1941 and 1945 when Imperial Japanese forces occupied the Gilbert Islands during World War II, in the Pacific War theatre.
Papua New Guinean nationality law is regulated by the 1975 Constitution of Papua New Guinea, as amended; the Citizenship Act 1975, and its revisions; and international agreements entered into by the Papua New Guinean government. These laws determine who is, or is eligible to be, a national of Papua New Guinea. The legal means to acquire nationality, formal legal membership in a nation, differ from the domestic relationship of rights and obligations between a national and the nation, known as citizenship. Papua New Guinean nationality is typically obtained either on the principle of jus soli, i.e. by birth in Papua New Guinea or under the rules of jus sanguinis, i.e. by birth abroad to parents with Papua New Guinean nationality. It can be granted to persons who have lived in the country for a specific period of time, who have contributed to the country's development, or who have an affiliation to the country through naturalization.
