  • Radiocarbon dating suggests that Bikini Atoll may have been inhabited as early as 1200 BCE. Archaeological digs on other atolls found evidence of human habitation around the 1st century CE at the village of Laura on Majuro and on Kwajalein Atoll. The first Austronesian settlers arrived from the Solomon Islands and introduced Southeast Asian crops like coconuts, giant swamp taro, and breadfruit. They also brought domesticated chickens which made the islands permanently habitable. These settlers possibly seeded the islands by leaving coconuts at seasonal fishing camps before settling years later. Southern atolls received heavier rainfall than the north so communities in the wet south subsisted on prevalent taro and breadfruit. Northerners were more likely to subsist on pandanus and coconuts. Southern atolls probably supported larger, more dense populations. Marshallese sailors navigated between islands using walaps made from breadfruit-tree wood and coconut-fiber rope. They used stars for orientation but developed a piloting technique interpreting disruptions in ocean swells to locate low coral atolls below the horizon. When refracted swells from different directions met they created noticeable disruption patterns. Marshallese pilots could read these patterns to determine the direction of an island. Some Marshallese sailors noted that they piloted their canoes by both sight and feeling changes in the motion of the boat. Sailors invented stick charts to map swell patterns but unlike western navigational charts these were tools for teaching students and consultation before embarking on a voyage. Navigators did not take charts with them when they set sail.

  • On the 21st of August 1526, Spanish explorer Alonso de Salazar was the first European to sight the Marshall Islands while commanding the Santa Maria de la Victoria. The crew could not land because of strong currents and water too deep for the ship's anchor so the ship sailed for Guam two days later. On the 2nd of January 1528, the expedition of Álvaro de Saavedra Cerón landed on an uninhabited island possibly in Ailinginae Atoll where they resupplied and stayed for six days. Natives from a neighboring island briefly met the Spanish. This expedition named the islands 'Los Pintados' or 'the Painted Ones' for the natives who wore tattoos. From the 1820s through the 1850s, the Marshall Islanders became increasingly hostile to western vessels. One of the earliest violent encounters occurred in February 1824 when the inhabitants of Mili Atoll massacred marooned sailors from the American whaler Globe. Similar encounters occurred as late as 1851 and 1852 when three separate Marshallese attacks on ships occurred at Ebon, Jaluit, and Namdrik Atolls. In 1875, British and German governments conducted secret negotiations to divide the Western Pacific into spheres of influence. The German sphere included the Marshall Islands. On the 26th of November 1878, the German warship SMS Ariadne anchored at Jaluit to begin treaty negotiations with chiefs. During the second day of negotiations Captain Werner signed a treaty with Kabua and several other Ralik Chain iroij which secured a German fuelling station at Jaluit. On the 29th of August 1885, German Chancellor Otto von Bismarck authorized the annexation of the Marshall Islands as a protectorate following repeated petitions by German business interests. The German gunboat docked at Jaluit on October 13 to take control. On October 15, iroij Kabua, Loeak, Nelu, Lagajime, and Launa signed a protection treaty in German and Marshallese at the German consulate. A company of German marines hoisted the flag of the German Empire over Jaluit and performed similar ceremonies at seven other atolls in the Marshalls. The Imperial Japanese Navy invaded Enewetak on the 29th of September 1914, and Jaluit on September 30 at the beginning of World War I. An occupation force was stationed on Jaluit on October 3. At the Paris Peace Conference in 1919, Germany's Pacific colonies north of the equator became the Japanese South Seas Mandate under the system of League of Nations mandates. Germany ceded the Marshall Islands to Japan with the signing of the Treaty of Versailles on the 28th of June 1919.

  • From 1946 to 1958, it served as the Pacific Proving Grounds for the United States and was the site of 67 nuclear tests on various atolls. Operation Crossroads atomic bomb testing began in 1946 on Bikini Atoll after some of the residents were forcibly evacuated. The world's first hydrogen bomb, codenamed 'Mike', was tested at the Enewetak atoll in the Marshall Islands on November 1 (local date) in 1952 which produced significant fallout in the region. The Castle Bravo test of the first deployable thermonuclear bomb had unforeseen additional nuclear reactions involving lithium-7 that resulted in the explosion being over twice as large as predicted resulting in much larger nuclear fallout than expected. The nuclear fallout spread eastward onto the inhabited Rongelap and Rongerik Atolls. These islands were not evacuated before the explosion. Many of the Marshall Islands natives have since suffered from radiation burns and radioactive dusting suffering similar fates as the Japanese fishermen aboard the Daigo Fukuryū Maru but have received little if any compensation from the federal government. Over the years just one of over 60 islands was cleaned by the U.S. government and the inhabitants are still waiting for the 2 billion dollars in compensation assessed by the Nuclear Claims Tribunal. Many of the islanders and their descendants still live in exile as the islands remain contaminated with high levels of radiation. A significant radar installation was constructed on Kwajalein atoll. The Runit Dome was built on Runit Island to deposit U.S.-produced radioactive soil and debris including lethal amounts of plutonium. There are ongoing concerns about deterioration of the waste site and a potential radioactive spill.

  • In 1947, the United States entered into an agreement with the UN Security Council to administer much of Micronesia including the Marshall Islands as the Trust Territory of the Pacific Islands. On the 1st of May 1979, in recognition of the evolving political status of the Marshall Islands, the United States recognized the constitution of the Marshall Islands and the establishment of the Government of the Republic of the Marshall Islands. The constitution incorporates both American and British constitutional concepts. There have been a number of local and national elections since the Republic of the Marshall Islands was founded. The United Democratic Party won the 1999 general election taking control of the presidency and cabinet. It was not until 1999 following political corruption allegations that the aristocratic government was overthrown with Imata Kabua replaced by the commoner Kessai Note. The islands signed a Compact of Free Association with the United States in 1986. Trusteeship was ended under United Nations Security Council Resolution 683 of the 22nd of December 1990. Until 1999 the islanders received US$180 million for continued American use of Kwajalein atoll, US$250 million in compensation for nuclear testing, and US$600 million in other payments under the compact. In January 2016, senator Hilda Heine was elected by Parliament as the first female president of the Marshall Islands. Previous president Casten Nemra lost office in a vote of no confidence after serving two weeks. In January 2020, David Kabua son of founding president Amata Kabua was elected as the new President of the Marshall Islands. His predecessor Hilda Heine lost the position after a vote. Since the late 1980s, Marshallese have migrated to the US with over 4,000 in Arkansas and over 7,000 in Hawaii in the 2010 US Census.

  • The islands have few natural resources and their imports far exceed exports. According to the CIA the value of exports in 2013 was approximately $53.7 million while estimated imports were $133.7 million. The GDP in 2016 was an estimated $180 million with a real growth rate of 1.7%. The GDP per capita was $3,300. Majuro is the world's busiest tuna transshipment port with 704 transshipments totaling 444,393 tons in 2015. Majuro is also a tuna processing center; the Pan Pacific Foods plant exports processed tuna to a number of countries primarily the United States under the Bumble Bee brand. Fishing license fees primarily for tuna provide noteworthy income for the government. In 1999, a private company built a tuna loining plant with more than 400 employees mostly women but the plant closed in 2005 after a failed attempt to convert it to produce tuna steaks. Operating costs exceeded revenue and the plant closed. It was taken over by the government which had been the guarantor of a $2 million loan to the business. The Marshall Islands plays a vital role in the international shipping industry as a flag of convenience for commercial vessels. The Marshallese registry began operations in 1990 and is managed through a joint venture with International Registries Inc., a US-based corporation that has offices in major shipping centers worldwide. As of 2017, the Marshallese ship registry was the second largest in the world after that of Panama. Unlike some flag countries there is no requirement that a Marshallese flag vessel be owned by a Marshallese individual or corporation. Following the 2015 seizure of the MV Maersk Tigris the United States announced that its treaty obligation to defend the Marshall Islands did not extend to foreign-owned Marshallese flag vessels at sea. In 2018, the Republic of Marshall Islands passed the Sovereign Currency Act which was later repealed in August 2025. This was intended to launch a sovereign cryptocurrency and certify it as legal tender. In November 2025, the Ministry of Finance announced ENRA, a universal basic income program for disbursements of funds to citizens.

  • The country consists of a total of 29 atolls and five individual islands situated in about 180,000 square miles of the Pacific. The average altitude above sea level for the entire country is less than two meters. Climate change is a threat to the Marshall Islands with typhoons becoming stronger and sea levels rising. The sea around the Pacific islands has risen four millimeters a year since 1993 which is more than twice the worldwide average rate. In Kwajalein there is a high risk of permanent flooding; when sea level rises by one meter 37% of buildings will be permanently flooded. In Ebeye the risk from sea level rise is even higher with 50% of buildings being permanently flooded in the same scenario. With two meters of sea level rise all the buildings of Majuro will be permanently flooded or will be at a high risk of being flooded. Population has outstripped the supply of fresh water usually from rainfall. The northern atolls get 40 inches of rainfall annually while the southern atolls receive about twice that amount. The threat of drought is commonplace throughout the island chains. In October 2011, the government declared that an area covering nearly 600,000 square kilometers of ocean shall be reserved as a shark sanctuary. This is the world's largest shark sanctuary extending the worldwide ocean area in which sharks are protected from fishing. In early 2025, the Marshall Islands established its first marine protected area covering 48,000 sq kms around the northern atolls of Bikar and Bokak.
