Long ago, many people lived on New Guinea. 

Long ago, a land called New Guinea was changed. 

Long ago, different parts of New Guinea were ruled by other lands. In 1884, Germany took the northeast part. Britain took the southeast part. Later, Australia took control of the German lands. 
In 1920, a group called the League of Nations gave Australia a mandate. A mandate is a way to let one country lead another. Australia ruled the Territory of New Guinea for many years. During this time, people found gold in the mountains. They used big cargo planes to move heavy tools.
Then, a large war came to the islands. Japan took over much of the land. 
After the war ended, the two lands joined together. In 1949, Papua and New Guinea became one group. In 1971, the name changed to Papua New Guinea. This land is now its own country.

The Territory of New Guinea was a special area in the Pacific. It sat in the northeastern part of the island of New Guinea. Australia ruled this land for many years. This rule lasted from 1914 until 1975. At first, it was a mandate from the League of Nations. Later, it became a trust territory under the United Nations. 
Rules for this land changed many times. In 1884, the German Empire took the northeast part. This area was called German New Guinea. In that same year, Britain took the southeast part. They called it British New Guinea. Later, Australia took control of these lands. By 1906, Australia began to rule the Territory of Papua. In 1914, Australian forces captured German New Guinea during World War I. 
Life in the territory brought new discoveries and hard jobs. In 1921, people found gold in a place called Wau. Later, they found more gold at Edie Creek. Because there were no roads, people had to use planes. They flew heavy tools over the mountains. Between 1937 and 1938, Guinea Airways moved more cargo by air than the rest of the world combined. They used four Junkers G 31 cargo planes for this work.
War brought great changes and many struggles to the islands. During the Pacific War, Japan occupied most of the territory. Rabaul became a major base for the Japanese military. Australian and American soldiers fought to take the land back. Local Papuan people helped many hurt soldiers on the Kokoda Track. Australians called these kind helpers "Fuzzy Wuzzy Angels." 
After the war ended, the different parts began to join. In 1945, a new law combined Papua and New Guinea. This created an administrative union between the two lands. In 1949, they were officially united as one territory. The name was changed to Papua New Guinea in 1971. This long history led to the birth of the Independent State of Papua New Guinea. The territory kept its own identity through all these changes.
The Territory of New Guinea was a unique administrative region in the Pacific. It occupied the northeastern portion of New Guinea island and several nearby islands. Australia managed this territory for over sixty years, from 1914 until 1975. It functioned first as a League of Nations mandate. Later, it became a United Nations trust territory. This region held a distinct legal identity even when joined with other lands. Its history is a complex story of colonial shifts, resource rushes, and intense conflict.
Before the Australian era, the region was divided by European powers. In 1884, the German Empire claimed the northeast quarter as German New Guinea. That same year, the British government established a protectorate in the southeast. This area was called British New Guinea. In 1888, Britain annexed the protectorate directly. By 1902, the territory was transferred to the Commonwealth of Australia. Australian administration of the southern part, known as the Territory of Papua, began in 1906. 
World War I changed the control of the northern region. In October 1914, the Australian Naval and Military Expeditionary Force seized German New Guinea. They landed at places like Herbertshohe and Kabakaul to find German radio stations. The German administration surrendered on September 17, 1914. After the war, the Treaty of Versailles decided the fate of German colonies. Australia sought to keep New Guinea for strategic reasons. Prime Minister Billy Hughes argued the islands were as necessary to Australia as water to a city. Consequently, the League of Nations granted Australia a mandate to govern the territory in 1920.
Life in the Mandate New Guinea saw significant economic and social shifts. The Australian government expropriated land from German settlers starting in 1921. This caused economic stagnation because many new owners lacked tropical farming experience. However, the discovery of gold brought new energy to the region. Gold was found in Wau in 1921, and more was found at Edie Creek in 1926. Because the terrain was so rugged, pioneers used airplanes to move heavy equipment. Between 1937 and 1938, Guinea Airways used four Junkers G 31 cargo planes. They moved more air freight between Lae and Wau than the rest of the world combined. 
Natural disasters and war eventually disrupted this development. In 1937, the eruption of Mount Tavurvur and Matupit destroyed much of Rabaul. This forced the administration to move its seat to Lae. This stability ended with the outbreak of the Pacific War in 1941. Imperial Japan occupied much of the territory and turned Rabaul into a major military base. The fighting included the New Guinea campaign, which featured many difficult battles. Australian and American forces fought to stop the Japanese advance toward Port Moresby. 
One of the most famous struggles occurred along the Kokoda Track. Australian soldiers fought a rearguard action against Japanese forces in the Owen Stanley Ranges. During this time, local Papuan people provided vital assistance to the troops. They escorted injured soldiers down the difficult mountain paths. Australians referred to these helpers as "Fuzzy Wuzzy Angels." The fighting continued through major battles like Buna-Gona. The scale of the conflict was massive, involving hundreds of thousands of people. In total, about 200,000 Japanese personnel died during the New Guinea campaign.
After the Second World War ended in 1945, the administration changed again. The Papua New Guinea Provisional Administration Act of 1945–46 combined Papua and New Guinea. They formed an administrative union to manage the two regions together. In 1949, they were officially united as the Territory of Papua and New Guinea. This administrative name was eventually changed to Papua New Guinea in 1971. This process of unification and governance eventually led to the creation of the Independent State of Papua New Guinea in 1975.
