The Federated States of Micronesia (FSM) is an island country located in the Micronesian region of Oceania. This federation comprises the majority of the Caroline Islands, excluding Palau, and is made up of four states: Yap, Chuuk, Pohnpei, and Kosrae. Spanning the western Pacific just north of the equator, the nation includes around 607 islands with a combined land area that is relatively small. However, its waters occupy a vast expanse of the Pacific Ocean, granting it the fourteenth-largest exclusive economic zone globally. The capital is Palikir on Pohnpei Island, while the largest city is Weno, a municipality in the Chuuk Lagoon. Each state is centered on one or more main volcanic islands, and all except Kosrae include numerous outlying atolls.
The ancestors of the Micronesians settled over four thousand years ago, developing a decentralized chieftain system that eventually centralized around Yap Island. On Pohnpei, the site of Nan Madol—a UNESCO World Heritage Site of artificial islands linked by canals—served as the ceremonial and political seat of the Saudeleur dynasty from about AD 500 until its collapse around 1500. European contact began in the sixteenth century with Portuguese and Spanish explorers. The Spanish incorporated the archipelago into the Spanish East Indies, later establishing a settlement on Pohnpei. Following the Spanish–American War, Spain sold the islands to Germany in 1899. Japan captured the islands during World War I and administered them under a League of Nations mandate. During World War II, Truk Lagoon was a major Japanese base, heavily attacked by the U.S. Navy in Operation Hailstone in 1944. After the war, the islands became part of the United Nations Trust Territory of the Pacific Islands, administered by the United States. On May 10, 1979, four districts ratified a constitution to form the FSM. The nation became a sovereign state on November 3, 1986, under a Compact of Free Association with the United States, with independence formally concluded in 1990 when the UN ended trusteeship.

Lore & Background
The Federated States of Micronesia is an island country in the western Pacific Ocean, situated just north of the equator. Its territory encompasses the majority of the Caroline Islands, excluding Palau, and stretches from west to east across four states: Yap, Chuuk, Pohnpei, and Kosrae. The federation comprises around 607 islands, with a combined land area that is relatively small, though its surrounding waters occupy a vast expanse of the Pacific, granting it the 14th-largest exclusive economic zone in the world. Each state is centered on one or more main volcanic islands, and all except Kosrae include numerous outlying atolls. The nation’s capital is Palikir on Pohnpei Island, while its largest city is Weno, located in the Chuuk Lagoon. The islands lie northeast of Indonesia and Papua New Guinea, south of Guam and the Marianas, west of Nauru and the Marshall Islands, and east of Palau and the Philippines. The ancestors of the Micronesians settled over four thousand years ago, initially developing a decentralized chieftain-based system that later evolved into a more centralized culture centered on Yap. On Pohnpei, the site of Nan Madol—a UNESCO World Heritage Site consisting of small artificial islands linked by canals—served as the ceremonial and political seat of the Saudeleur dynasty, which united the island’s population from about AD 500 until its collapse around 1500. European contact began in the sixteenth century with Portuguese and Spanish explorers, and Spain later incorporated the archipelago into the Spanish East Indies, establishing outposts and missions. After the Spanish–American War, Germany purchased the islands in 1899 and incorporated them into German New Guinea. Japan captured the islands during World War I and administered them under a League of Nations mandate as part of the South Seas Mandate. During World War II, Chuuk Lagoon served as a major Japanese naval base, and in February 1944, the U.S. Navy launched Operation Hailstone, a massive air and surface attack that severely diminished Japan’s naval capabilities in the Pacific. Following the war, the United Nations placed the islands under U.S. administration as part of the Trust Territory of the Pacific Islands. On May 10, 1979, four of the trust territory’s districts ratified a constitution to become the Federated States of Micronesia, which became a sovereign state on November 3, 1
