In short: Rising from the western Pacific, Pohnpei is a high, rain-drenched volcanic island known for its rugged interior and ancient stone ruins. As the seat of government for the Federated States of Micronesia, this island serves as a cultural and political anchor within the vast Caroline Islands archipelago.

Pohnpei is a roughly square, mountainous island in the eastern Caroline Islands, reaching an elevation of 2,595 feet at Dolohmwar. Its geography is defined by high volcanic peaks, tropical rainforests, and a surrounding barrier reef. The island is exceptionally wet, receiving more than 200 inches of rainfall annually, which supports a diverse array of plant life, including the endemic ka tree. While the island is the most developed in the Federated States of Micronesia, its history is marked by the megalithic ruins of Nan Madol, a city built on artificial islands starting in the 8th or 9th century.

The island’s social history is traditionally divided into three distinct eras: the period of peopling before 1100, the Saudeleur dynasty from 1100 to 1628, and the nahnmwarki system that followed. The Saudeleur rulers, described in legend as foreign-born, centralized power until their oppressive rule was ended by the arrival of Isokelekel. Historically, Pohnpeian society was feudal and highly structured, with land ownership held by chiefs. European contact began in 1529 with Spanish navigator Álvaro de Saavedra Cerón, though the island remained largely isolated until the 19th century, when it became a hub for whalers and traders.

Today, Pohnpei is home to Palikir, the capital of the Federated States of Micronesia. The island contains about one-third of the nation's population and remains a center for government and commerce. While subsistence farming and fishing remain vital, the economy is heavily supported by U.S. grant aid under the Compact of Free Association. Culturally, the island is diverse; while most inhabitants are Pohnpeian, the state includes atolls like Kapingamarangi and Nukuoro, where the residents are Polynesian and speak unrelated languages. The population is predominantly Christian, with a significant majority identifying as Roman Catholic.
