Marshall Islands — map and facts

#### About Marshall Islands The Marshall Islands is a sovereign island nation located in the central Pacific Ocean, constituting part of the larger Micronesia region. Formally known as the Republic of the Marshall Islands, it gained independence from United States administration in 1986 under a Compact of Free Association that remains in effect today. The nation comprises approximately 1,225 islands and islets spread across 29 atolls and five isolated islands. With a population of around 42,000 people, the capital Majuro serves as the political, economic, and cultural hub. The Marshallese people have inhabited these islands for thousands of years, developing sophisticated navigation techniques using wave patterns and star charts. The country faces existential threats from rising sea levels linked to climate change, making it one of the most vulnerable nations on Earth to environmental shifts.

#### Geography and Landscape The Marshall Islands are divided into two parallel chains of atolls: the Ratak (Sunrise) Chain to the east and the Ralik (Sunset) Chain to the west. The total land area is only about 181 square kilometers, yet the islands are spread across roughly 1.9 million square kilometers of ocean. No point on any island rises more than two meters above sea level, making the entire nation exceptionally flat and low-lying. The atolls consist of coral reefs encircling shallow lagoons of turquoise water, with sandy islets dotting the reef crests. The largest atoll by land area is Kwajalein, which also contains the world's largest lagoon. The warm, clear waters surrounding the islands support rich marine biodiversity, including diverse coral ecosystems and abundant fish populations. Vegetation is primarily coconut palms, pandanus trees, and low scrub, adapted to the sandy, saline soils.

#### History Archaeological evidence suggests human settlement of the Marshall Islands dates back at least 2,000 years, with migrations from Southeast Asia shaping the original Marshallese culture. Spanish explorers made early European contact in the sixteenth century, with British captain John Marshall lending his name to the archipelago in 1788. Germany established a protectorate over the islands in 1885, administering them until Japan seized control during World War One. Japanese mandate rule lasted until World War Two, when American forces captured the islands following fierce battles at Kwajalein and Eniwetok in 1944. The United States subsequently used the Marshall Islands for extensive nuclear weapons testing between 1946 and 1958, including 67 tests that caused severe radioactive contamination, particularly on Bikini and Rongelap atolls. Displaced communities continue to seek justice and compensation. The islands moved toward self-governance in the 1970s and achieved full independence in 1986.
