The islands were settled around 1500 BC when various peoples migrated there. Eventually, the islands were claimed by
Spain in 1521. After their first contact with Spaniards, the islanders eventually became known as the
Chamorros, a Spanish word similar to
Chamori, the name of the Indigenous caste system's higher division. The ancient people of the Marianas raised
colonnades of megalithic-capped pillars called
latte stones upon which they built their homes. The Spanish reported that by their arrival, the largest of these was already in ruins and that the Chamorros believed the ancestors who had erected the pillars lived in an era when people possessed supernatural abilities. In 2013 archaeologists posited that the first people to settle in the Marianas may have made what was at that point the longest uninterrupted ocean-crossing voyage in human history.
Archeological evidence indicates that
Tinian may have been the first Pacific island to be settled.
Spanish possession by the
Chamorro in the
Ladrones Islands, c. 1590. From
Boxer Codex. The Portuguese navigator
Ferdinand Magellan, sailing under the Spanish flag, arrived in 1521. He and his crew were the first Europeans to arrive in the Mariana Islands. He landed on Guam, the southernmost island of the Marianas, and claimed the archipelago for Spain. The Spanish ships were met offshore by the native Chamorros, who delivered refreshments and then helped themselves to a small boat belonging to Magellan's fleet. This led to a cultural clash: in Chamorro tradition, little property was private, and taking something one needed, such as a boat for fishing, did not count as stealing. The Spanish did not understand this custom and fought the Chamorros until the boat was recovered. Three days after he had been welcomed on his arrival, Magellan fled the archipelago. Spain regarded the islands as annexed and later made them part of the
Spanish East Indies in 1565. In 1734, the Spanish built a royal palace, the
Plaza de España, in Guam for the governor of the islands. The palace was largely destroyed during World War II, but portions of it remain. Guam operated as an important stopover between the Philippines and
Mexico for the
Manila galleon, which carried trading between Spanish colonies. In 1668, Father
Diego Luis de San Vitores renamed the islands
Las Marianas in honor of his patroness, the Spanish regent
Mariana of Austria (1634–1696), widow of
Felipe IV (reigned 1621–1665). Most of the islands' native population (90–95%) died from European diseases carried by the Spaniards or married non-Chamorro settlers under Spanish rule. New settlers from the Philippines and the Caroline Islands were brought to repopulate the islands. The Chamorro population gradually recovered, and Chamorro,
Filipino, and
Refaluwasch languages and other ethnic groups remain in the Marianas. During the 17th century, Spanish colonists forcibly moved the Chamorros to Guam, to encourage assimilation and conversion to
Roman Catholicism. By the time they were allowed to return to the Northern Marianas, many Carolinians from present-day eastern
Yap State and western
Chuuk State had settled in the Marianas. Both languages, as well as English, are now official in the commonwealth. In 1720 the Spanish moved the remaining islanders, whose population had been decimated by diseases, from the Marianas to Guam. By 1741, there were about 5000 remaining Chamorros.
German possession and Japanese mandate Following its loss during the
Spanish–American War of 1898,
Spain ceded Guam to the United States and sold the remainder of the
Marianas (i.e., the Northern Marianas), along with the Caroline Islands, to
Germany under the
German–Spanish Treaty of 1899. The United States could have taken the entire Marianas, but beyond Guam, saw no need for the group. Germany administered the islands as part of its colony of
German New Guinea and did little in terms of development. Germany built an office on Saipan to administer the island, and the head administrator was Georg Fritz. The Germans established a public school system and homesteading program, and some efforts were put into
copra production; there was an overall effort to grow the economy with roads being built and vocational/trades training. Pagan and Alamagan were leased to a company called Pagan Gesellschaft, which planned to produce copra there, although its goals were hampered by numerous
typhoons. Eight islands were leased to bird hunters, which used the feathers for hats.
World War II in
Garapan, Saipan On December 8, 1941, hours after the
attack on Pearl Harbor, Japanese forces from the Marianas launched an
invasion of Guam. Chamorros from the Northern Marianas, which had been under Japanese rule for more than 20 years, were brought to Guam to assist the Japanese administration. This, combined with the harsh treatment of Guamanian Chamorros during the 31-month occupation, created a rift that would become the main reason Guamanians rejected
the referendum on the reunification of Guam with the Northern Marianas that the Northern Marianas approved in the 1960s. On June 15, 1944, the United States military invaded the Mariana Islands, starting the
Battle of Saipan, which ended on July 9. Of the 30,000 Japanese troops defending Saipan, fewer than 1,000 remained alive at the battle's end. Many civilians were also killed, by disease, starvation, enemy fire, or suicide; about 1,000 civilians killed themselves by jumping off cliffs. U.S. forces then recaptured Guam on July 21, and
invaded Tinian on July 24. A year later,
Tinian was the takeoff point for the
Enola Gay, the plane that dropped the atomic bomb on
Hiroshima.
Rota was left untouched (and isolated) until the
Japanese surrender in August 1945, owing to its military insignificance and U.S. forces' strategy of "island hopping" in which they did not invade islands that they did not need. The war did not end for everyone with the signing of the armistice. A large group of
Japanese holdouts surrendered on Saipan on December 1, 1945. However, a group of about 30 held out until 1951 on
Anatahan; their story was told in the film
The Saga of Anatahan. On a related note, on Guam, Japanese soldier
Shoichi Yokoi, unaware that the war had ended, hid in a jungle cave in the
Talofofo area until 1972. Japanese nationals were eventually repatriated to the
Japanese home islands. After World War II, the people of Marianas were able to return to the Northern Marianas under the protection of the United Nations Trusteeship administered by the United States. During this time, a series of referendums took place.
United Nations trusteeship ends, Commonwealth begins After Japan's defeat in World War II, the Northern Marianas were administered by the United States pursuant to
Security Council Resolution 21 as part of the United Nations
Trust Territory of the Pacific Islands, which assigned responsibility for defense and foreign affairs to the United States as trustee. In the
1975 Northern Mariana Islands status referendum nearly 80% voted to become a commonwealth of the United States, and in 1977 over 93% approved the constitution of the CNMI. (left) in the United States The people of the Northern Mariana Islands decided in the 1970s not to seek independence, but instead to forge closer links with the United States. Negotiations for
commonwealth status began in 1972, and a covenant to establish a commonwealth in political union with the United States was approved in a
1975 referendum. Also on November 4, 1986, the
Northern Mariana Islands constitution became fully effective under the Covenant. In December 1986, 20 percent of the homes on Saipan were destroyed by
Typhoon Kim, trees were stripped of foliage, thousands of coconut trees were knocked down, roads were blocked, and there was no electricity or public water supply for weeks.
Twenty-first century eruption in 2012 The Northern Mariana Islands does not have voting representation in the
United States Congress, but, since 2009, has been represented in the
U.S. House of Representatives by a
delegate; congressional delegates may participate in debates and serve on congressional committees but may not cast decisive votes on the House floor. In the United States, a non-voting delegate is not a new concept, but rather goes back to before 1800. Territorial delegates represent their region's interest in Congress, and their powers have been established over time, beginning in 1795. A major power of the territorial delegates (which have also been called Resident Commissioners), besides serving on committees, is speaking on the floor. Perhaps more importantly, the position is seen as a precursor to establishing voting rights, and discussion about granting delegate voting rights has occurred. One returning Marianan remarked, "I was born and raised on Saipan but my family is from Alamagan. We are going to live there for a long time."
Typhoon Yutu caused widespread damage in October 2018, and was the strongest typhoon known to hit the islands.
Federal Emergency Management Agency (FEMA) personnel deployed to both Tinian and Saipan ahead of the storm. U.S. President Donald Trump declared an emergency for the Northern Islands on October 24, 2018. ==Geography==
