Northern Mariana Islands profile

The Commonwealth of the Northern Mariana Islands (CNMI) is a self-governing commonwealth of the United States.

It includes the 14 northernmost islands in the Mariana archipelago - the southernmost island Guam is a separate US territory. The islands lie 2,400km south of Japan.

Those born on the islands are US citizens but not eligible to vote in presidential elections. The territory receives millions of dollars in aid from Washington.

Most of the population live on the island of Saipan, and only four other islands are populated. Native Micronesians outnumber the indigenous Chamorro and Carolinian populations.

Like other remote islands, the CNMI faces the challenge of declining population numbers, leading to falling tax revenues and pressures on public services.

Some key events in Northern Marianas' history:

1500-1400BC - Islands first settled by migrants from the Philippines, followed by later migrations from the Caroline islands and then from the Philippines or eastern Indonesia.

1521 - Portuguese navigator Ferdinand Magellan land on Guam. He and his crew are the first Europeans to arrive in the Marianas. He claims the archipelago for Spain.

1565 - Spain incorporates the islands into the Spanish East Indies. Guam becomes an important stopover between the Philippines and Mexico for the Manila galleons trading between Spanish colonies.

1668 - The islands are named Las Marianas, after the Spanish regent Mariana of Austria (1634-1696)

16th-18th Centuries - After first contact with the Spanish, the inhabitants become known as the Chamorros, a Spanish word similar to Chamori, the name of the indigenous caste system's higher division.

Between 90-95% of the islands' population dies from European diseases carried by the Spanish or marries non-Chamorro settlers under Spanish rule. New settlers, primarily from the Philippines and the Caroline Islands, are brought in to repopulate the islands.

1898 - Spanish-American War. US takes Guam from the Spanish.

1899 - Spain cedes Guam to the US and sells the Northern Marianas and Caroline Islands to Germany under 1899 German-Spanish Treaty.

1899-1914 - Germany administers the islands as part of its colony of German New Guinea.

1914 - Shortly after the outbreak of World War One, Japan seizes the islands from Germany and annexes them.

1919 - Following World War One, the League of Nations formally places the islands under Japanese administration as part of its South Seas Mandate.

1941 - Immediately after its attack on the US navy at Pearl Harbor during World War Two, Japanese forces from the Marianas invade Guam.

1944 - Battle of the Marianas. US forces invade the Marianas. Of the 30,000 Japanese troops defending Saipan, fewer than 1,000 remain a the end. Many civilians are also killed - including about 1,000 civilians who kill themselves by jumping off cliffs.

1958-1969 - Northern Marianas votes four times in favour of integration with Guam, but Guam rejects integration in a 1969 referendum.
