Palau in the context of Ngerdorch River

A microstate or ministate is a sovereign state having a very small population or land area, usually both. However, the meanings of "state" and "very small" are not well-defined in international law. Some recent attempts to define microstates have focused on identifying qualitative features that are linked to their size and population, such as partial delegation of their sovereignty to larger states, such as for international defense.

Commonly accepted examples of microstates include five historic European microstates: Andorra, Liechtenstein, Monaco, San Marino, and Vatican City. Malta and Luxembourg are sometimes included in that list but are generally considered too populous to be genuine microstates. Other examples are small, isolated island states in the Pacific Ocean: Nauru, Palau, Niue, Cook Islands and Tuvalu. Some small Caribbean countries such as Saint Kitts and Nevis, Barbados, Antigua and Barbuda, Grenada, Saint Vincent and the Grenadines may be considered microstates by some but are often not included due to them being grouped together as small island countries. Singapore and Bahrain are sometimes considered microstates but some argue are too populous, self reliant or powerful to be considered true microstates and their island status can play an important factor too.The smallest political entity recognized as a sovereign state is Vatican City, with fewer than 1,000 residents and an area of only 49 hectares (120 acres). Some microstates – such as Singapore, Monaco and Vatican City – are city-states consisting of a single municipality.

Indonesia, officially the Republic of Indonesia, is a country in Southeast Asia and Oceania, between the Indian and Pacific oceans. Comprising over 17,000 islands, including Sumatra, Java, Sulawesi, and parts of Borneo and New Guinea, Indonesia is the world's largest archipelagic state and the 14th-largest country by area, at 1,904,569 square kilometres (735,358 square miles). With over 280 million people, Indonesia is the world's fourth-most-populous country and the most populous Muslim-majority country. Java, the world's most populous island, is home to more than half of the country's population.

Indonesia operates as a presidential republic with an elected legislature and consists of 38 provinces, nine of which have special autonomous status. Jakarta, the largest city, is the world's second-most-populous urban area. Indonesia shares land borders with Papua New Guinea, Timor-Leste, and East Malaysia, as well as maritime borders with Singapore, Peninsular Malaysia, Vietnam, Thailand, the Philippines, Australia, Palau, and India. Despite its large population and densely populated regions, Indonesia has vast areas of wilderness that support one of the world's highest levels of biodiversity.

The Philippine Sea is a marginal sea of the Western Pacific Ocean east of the Philippine Archipelago and the largest sea in the world, occupying an estimated surface area of 5 million square kilometers (2×10^ sq mi). The Philippine Sea Plate forms the floor of the sea. Its western border is the first island chain to the west, comprising the Ryukyu Islands in the northwest and Taiwan in the west. Its southwestern border comprises the Philippine islands of Luzon, Catanduanes, Samar, Leyte, and Mindanao. Its northern border comprises the Japanese islands of Honshu, Shikoku and Kyūshū. Its eastern border is the second island chain to the east, comprising the Bonin Islands and Iwo Jima in the northeast, the Mariana Islands (including Guam, Saipan, and Tinian) in the due east, and Halmahera, Palau, Yap and Ulithi (of the Caroline Islands) in the southeast. Its southern border is Indonesia's Morotai Island.

The sea has a complex and diverse undersea relief. The floor is formed into a structural basin by a series of geologic faults and fracture zones. Island arcs, which are actually extended ridges protruding above the ocean surface due to plate tectonic activity in the area, enclose the Philippine Sea to the north, east and south. The Philippine archipelago, Ryukyu Islands, and the Marianas are examples. Another prominent feature of the Philippine Sea is the presence of deep sea trenches, among them the Philippine Trench and the Mariana Trench, containing the deepest point on the planet.

The United Nations Trusteeship Council is one of the six principal organs of the United Nations, established to help ensure that trust territories were administered in the best interests of their inhabitants and of international peace and security.

The trust territories—most of them former mandates of the League of Nations or territories taken from nations defeated at the end of World War II—have all now attained self-government or independence, either as separate nations or by joining neighbouring independent countries. The last was Palau, formerly part of the Trust Territory of the Pacific Islands, which became a member state of the United Nations in December 1994.

The Philippines, officially known as the Republic of the Philippines, is an archipelagic country in Southeast Asia. Located in the western Pacific Ocean, it consists of 7,641 islands, with a total area of roughly 300,000 square kilometers, which are broadly categorized in three main geographical divisions from north to south: Luzon, Visayas, and Mindanao. With a population of over 112 million, it is the world's fourteenth-most-populous country.

The Philippines is bounded by the South China Sea to the west, the Philippine Sea to the east, and the Celebes Sea to the south. It shares maritime borders with Taiwan to the north, Japan and the Korean Peninsula to the northeast, Palau to the east and southeast, Indonesia to the south, Malaysia to the southwest, Vietnam to the west, and China to the northwest. It has diverse ethnicities and a rich culture. Manila is the country's capital, and its most populated city is Quezon City. Both are within Metro Manila.

The Federated States of Micronesia (/ˌmaɪkroʊˈniːʒə/ , abbreviated FSM), or simply Micronesia, is an island country in Micronesia, a region of Oceania. The federation encompasses the majority of the Caroline Islands (excluding Palau) and consists of four states—from west to east: Yap, Chuuk, Pohnpei, and Kosrae—that span the western Pacific just north of the equator for a longitudinal distance of almost 2,700 km (1,700 mi). Together, the states comprise around 607 islands and a combined land area of approximately 702 km or 271 sq mi.

The entire island nation lies across the northern Pacific accordingly: northeast of Indonesia and Papua New Guinea, south of Guam and the Marianas, west of Nauru and the Marshall Islands, east of Palau and the Philippines, about 2,900 km (1,800 mi) north of eastern Australia, 3,400 km (2,100 mi) southeast of Japan, and some 4,000 km (2,485 mi) southwest of Honolulu of the Hawaiian Islands.

The Caroline Islands (or the Carolines) are a widely scattered archipelago of tiny islands in the western Pacific Ocean, to the north of New Guinea. Politically, they are divided between the Federated States of Micronesia (FSM) in the central and eastern parts of the group, and Palau at the extreme western end. Historically, this area was also called Nuevas Filipinas or New Philippines, because they were part of the Spanish East Indies and were governed from Manila in the Philippines.

The Carolines are scattered across a distance of approximately 3,540 kilometres (1,910 nmi), from the westernmost island, Tobi, in Palau, to the easternmost island, Kosrae, a state of the FSM.

Koror is the state comprising the main commercial centre of the Republic of Palau. It consists of several islands, the most prominent being Koror Island (also Oreor Island). It is Palau's most populous state; more people live in Koror than in the rest of Palau.

Koror (English: /ˈkɔːˌrɔːr/, KAW-rawr;) is the largest city and the commercial centre in Palau, home to about half of the country's population, located on Koror Island (also Oreor Island).

Ngerulmud (Palauan pronunciation: [ŋəˈɾulmuð]) is the seat of government of the Republic of Palau, an island nation in the Pacific Ocean. It replaced Koror City as a capital in October 2006. The settlement is located in the state of Melekeok on Babeldaob, the country's largest island, located 20 kilometers (12 miles) northeast of Koror City and 2 km (1 mile) northwest of Melekeok City.With no permanent fixed population, it is the least-populous capital city of a sovereign nation in the world.

Babeldaob (also Babelthuap) is the largest island in the island nation of Palau. It is in the western Caroline Islands, and the second largest island (after Guam) in the Micronesia region of Oceania. Palau's capital, Ngerulmud, is located on Babeldaob, in Melekeok State.

Babeldaob is one of the most underdeveloped populated islands in the Pacific Ocean. The area of Babeldaob, 331 km (128 sq mi), makes up over 70% of the land area of the entire Republic of Palau. It has about 30% of the country's population, with about 6,000 people living on it.

Melekeok is a state of the Republic of Palau located on the central east coast of Babeldaob Island. The seat of government of the country, Ngerulmud, is located in the state. The state consists of long beaches, hills, steep ridges, rivers, and the largest and only natural freshwater lake in Palau and Micronesia, Lake Ngardok.

The following is a list of countries and territories where English is an official language used in citizen interactions with government officials. As of 2025, there are 58 sovereign states and 28 non-sovereign entities where English is an official language. Many administrative divisions have declared English an official language at the local or regional level.

Most states where English is an official language are former territories of the British Empire. Exceptions include Rwanda and Burundi, which were formerly German and then Belgian colonies; Cameroon, where only part of the country was under the British mandate; and Liberia, the Philippines, the Federated States of Micronesia, the Marshall Islands, and Palau, which were American territories. English is the sole official language of the Commonwealth of Nations and of the Association of Southeast Asian Nations (ASEAN). English is one of the official languages of the United Nations, the European Union, the African Union, the Organisation of Islamic Cooperation, the Caribbean Community, the Union of South American Nations, and many other international organisations.

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 Republic of the Marshall Islands.

In Japan, the territory is known as "Japanese Mandate for the Governance of the South Seas Islands" (委任統治地域南洋群島, Inin tōchi chiiki nan'yō guntō) and was governed by the Nan'yō Government (南洋廳, Nan'yō-chō).

The Micronesians or Micronesian peoples are various closely related ethnic groups native to Micronesia, a region of Oceania in the Pacific Ocean. They are a part of the Austronesian ethnolinguistic group, which has an Urheimat in Taiwan.

Ethno-linguistic groups classified as Micronesian include the Carolinians (Northern Mariana Islands), Chamorros (Guam & Northern Mariana Islands), Chuukese, Mortlockese, Namonuito, Paafang, Puluwat and Pollapese (Chuuk), I-Kiribati (Kiribati), Kosraeans (Kosrae), Marshallese (Marshall Islands), Nauruans (Nauru), Palauan, Sonsorolese, and Hatohobei (Palau), Pohnpeians, Pingelapese, Ngatikese, Mwokilese (Pohnpei), and Yapese, Ulithian, Woleian, Satawalese (Yap).

The Compacts of Free Association (COFA) are international agreements establishing and governing the relationships of free association between the United States and the three Pacific Island sovereign states of the Federated States of Micronesia (FSM), the Republic of the Marshall Islands (RMI), and the Republic of Palau. As a result, these countries are sometimes known as the Freely Associated States (FASs). All three agreements next expire in 2043.

These countries, together with the Commonwealth of the Northern Mariana Islands, formerly constituted the Trust Territory of the Pacific Islands, a United Nations trusteeship administered by the United States Navy from 1947 to 1951, and by the U.S. Department of the Interior from 1951 to 1986 (to 1994 for Palau).

The Trust Territory of the Pacific Islands (TTPI) was a United Nations trust territory in Micronesia administered by the United States from 1947 to 1994. The Imperial Japanese South Seas Mandate had been seized by the US during the Pacific War, as Japan had administered the territory since the League of Nations gave Japan a mandate over the area from Imperial Germany after World War I. However, in the 1930s, Japan left the League of Nations and invaded additional lands. During World War II, military control of the islands was contested, but by the war's end, the islands had come under the Allies' control. The Trust Territory of the Pacific was created to administer the islands as part of the United States while still under the auspices of the United Nations. Most of the island groups in the territory became independent states, with some degree of association kept with the United States: the Federated States of Micronesia, the Republic of the Marshall Islands and Palau are independent states in a Compact of Free Association with the US, while the Northern Mariana Islands remain under US jurisdiction, as an unincorporated territory and commonwealth.

German New Guinea (German: Deutsch-Neuguinea) consisted of the northeastern part of the island of New Guinea and several nearby island groups, and was 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 (New Britain, New Ireland and several smaller islands), and the North Solomon Islands were declared a German protectorate in 1885. The Caroline Islands, Palau, and the Mariana Islands (except for Guam) 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.

Following the outbreak of World War I in 1914, Kaiser-Wilhelmsland and nearby islands fell to Australian forces, while Japan occupied most of the remaining German possessions in the Pacific. The mainland part of German New Guinea (Kaiser-Wilhelmsland), the Bismarck Archipelago and the North Solomon Islands are now part of Papua New Guinea. The Northern Mariana Islands are an unincorporated territory of the United States. The Carolines (as the Federated States of Micronesia), the Marshall Islands, Nauru and Palau are independent countries.
