Empire Of Japan
The also known as the Japanese Empire or Imperial Japan, was a historical nation-state and great power that existed from the Meiji Restoration in 1868 until the enactment of the post-World War II 1947 constitution and subsequent formation of modern Japan. It encompassed the Japanese archipelago and several colonies, protectorates, mandates, and other territories. Under the slogans of and following the Boshin War and restoration of power to the Emperor from the Shogun, Japan underwent a period of industrialization and militarization, the Meiji Restoration, which is often regarded as the fastest modernisation of any country to date. All of these aspects contributed to Japan's emergence as a great power and the establishment of a colonial empire following the First Sino-Japanese War, the Boxer Rebellion, the Russo-Japanese War, and World War I. Economic and political turmoil in the 1920s, including the Great Depression, led to the rise of militarism, nationa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Territory Of New Guinea
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 initial Australian mandate, entitled the Mandate for the German Possessions in the Pacific Ocean situated South of the Equator other than German Samoa and Nauru, was based on the previous German New Guinea, which had been captured and occupied by Australian forces during World War I. Most of the Territory of New Guinea was occupied by Japan during World War II, between 1942 and 1945. During this time, Rabaul, on the is ...

Minelayer
A minelayer is any warship, submarine or military aircraft deploying explosive mines. Since World War I the term "minelayer" refers specifically to a naval ship used for deploying naval mines. "Mine planting" was the term for installing controlled mines at predetermined positions in connection with coastal fortifications or harbor approaches that would be detonated by shore control when a ship was fixed as being within the mine's effective range. Before World War I, mine ships were termed mine planters generally. For example, in an address to the United States Navy ships of Mine Squadron One at Portland, England, Admiral Sims used the term “mine layer” while the introduction speaks of the men assembled from the “mine planters”. During and after that war the term "mine planter" became particularly associated with defensive coastal fortifications. The term "minelayer" was applied to vessels deploying both defensive- and offensive mine barrages and large scale sea mining. " ...

Rear Admiral
Rear admiral is a senior naval flag officer rank, equivalent to a major general and air vice marshal and above that of a commodore and captain, but below that of a vice admiral. It is regarded as a two star "admiral" rank. It is often regarded as a two-star rank with a NATO code of OF-7. The term originated in the days of naval sailing squadrons and can trace its origins to the Royal Navy. Each naval squadron was assigned an admiral as its head, who commanded from the centre vessel and directed the squadron's activities. The admiral would in turn be assisted by a vice admiral, who commanded the lead ships that bore the brunt of a battle. In the rear of the squadron, a third admiral commanded the remaining ships and, as this section was considered to be in the least danger, the admiral in command of it was typically the most junior. This has continued into the modern age, with rear admiral the most junior admiralty of many navies. In most European navies, the equivalent rank i ...

Invasion Of Tulagi (May 1942)
The invasion of Tulagi, on 3–4 May 1942, was part of Operation Mo, the Empire of Japan's strategy in the South Pacific and South West Pacific Area in 1942. The plan called for Imperial Japanese Navy troops to capture Tulagi and nearby islands in the British Solomon Islands Protectorate. The occupation of Tulagi by the Japanese was intended to cover the flank of and provide reconnaissance support for Japanese forces that were advancing on Port Moresby in New Guinea, provide greater defensive depth for the major Japanese base at Rabaul, and serve as a base for Japanese forces to threaten and interdict the supply and communication routes between the United States and Australia and New Zealand. Without the means to effectively resist the Japanese offensive in the Solomons, the British Resident Commissioner of the Solomon Islands protectorate and the few Australian troops assigned to defend Tulagi evacuated the island just before the Japanese forces arrived on 3 May.

In chemistry, a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate, a derivative of orthophosphoric acid . The phosphate or orthophosphate ion is derived from phosphoric acid by the removal of three protons . Removal of one or two protons gives the dihydrogen phosphate ion and the hydrogen phosphate ion ion, respectively. These names are also used for salts of those anions, such as ammonium dihydrogen phosphate and trisodium phosphate.

Samarai
Samarai is an island and former administrative capital in Milne Bay Province, Papua New Guinea. The island is historically significant as the site of a trading port and stop-over between Australia and East Asia. Samarai town was established on the island and at its height was the second largest after Port Moresby in the Territory of Papua. The town of Samarai was ordered to be destroyed by the British during World War II, fearing Japanese occupation. Although rebuilt after the war, and functioning as provincial headquarters until 1968, economic changes meant that Samarai did not fully regain its regional status and it has since largely fallen into disrepair.

Tulagi
Tulagi, less commonly known as Tulaghi, is a small island——in Solomon Islands, just off the south coast of Ngella Sule. The town of the same name on the island (pop. 1,750) was the capital of the British Solomon Islands Protectorate from 1896 to 1942 and is today the capital of the Central Province. The capital of what is now the state of Solomon Islands moved to Honiara, Guadalcanal, after World War II. The island was originally chosen by the British as a comparatively isolated and healthier alternative to the disease-ridden larger islands of the Solomon Islands archipelago. In October 2019, the government of Central Province signed a deal to grant the 75-year lease of the entire island of Tulagi to a Chinese company China Sam Enterprise Group. However, this was declared unconstitutional by the Solomon Islands parliament after a week and, consequently, the deal was cancelled.
