Micronesia

The ancestors of the Micronesians settled over four thousand years ago. A decentralized chieftain-based system eventually evolved into a more centralized economic and religious culture centered on Yap Island. Nan Madol, a UNESCO World Heritage Site, consisting of a series of small artificial islands linked by a network of canals, is often called the Venice of the Pacific. It is located on the eastern periphery of the island of Pohnpei and used to be the ceremonial and political seat of the Saudeleur dynasty that united Pohnpei's estimated 25,000 people from about AD 500 until 1500 when the centralized system collapsed. European explorers—first the Portuguese in search of the Spice Islands (Indonesia) and then the Spanish—reached the Carolines in the sixteenth century. …

The Federated States of Micronesia consists of 607 islands extending 2,900 km (1,802 mi) across the archipelago of the Caroline Islands east of the Philippines. The islands have a combined area of 702 km2 (271 sq mi). The islands are grouped into four states, which are Yap, Chuuk (called Truk until January 1990), Pohnpei (known as "Ponape" until November 1984), and Kosrae (formerly Kusaie). These four states are each represented by a white star on the national flag. The capital is Palikir, on Pohnpei. Two terrestrial ecoregions lie within the country's borders: Carolines tropical moist forests and Yap tropical dry forests. It had a 2019 Forest Landscape Integrity Index mean score of 7.55/10, ranking it 37th globally out of 172 countries. The Federated States of Micronesia (FSM) is recognized as a biodiversity hotspot, hosting approximately 3,025 animal species and 1,553 plant species. …

Each of the four states has its own culture and traditions, but there are also common cultural and economic bonds that are centuries old. Cultural similarities include the importance of the traditional extended family and clan systems and are found on all the islands. The island of Yap is notable for its "stone money" (Rai stones), large disks usually of calcite, up to 4 meters (13 ft) in diameter, with a hole in the middle. The islanders, aware of the owner of a piece, do not necessarily move them when ownership changes. There are five major types: Mmbul, Gaw, Ray, Yar, and Reng, the last being only 30 cm (12 in) in diameter. Their value is based on both size and history, many of them having been brought from other islands, as far as New Guinea, but most coming in ancient times from Palau. Approximately 6,500 of them are scattered around the island. …
