Micronesian people in the context of "Chamorro people"

The history of navigation, or the history of seafaring, is the art of directing vessels upon the open sea through the establishment of its position and course by means of traditional practice, geometry, astronomy, or special instruments. Many peoples have excelled as seafarers, prominent among them the Austronesians (Islander Southeast Asians, Malagasy, Islander Melanesians, Micronesians, and Polynesians), the Harappans, the Phoenicians, the Iranians, the ancient Greeks, the Romans, the Arabs, the ancient Indians, the Norse, the Chinese, the Venetians, the Genoese, the Hanseatic Germans, the Portuguese, the Spanish, the English, the French, the Dutch, and the Danes.

The demographics of Nauru, an island country in the Pacific Ocean, are known through national censuses, which have been analysed by various statistical bureaus since the 1920s. The Nauru Bureau of Statistics have conducted this task since 1977—the first census since Nauru gained independence in 1968. The most recent census of Nauru was on 30 October 2021, when population had reached 11,680 people. The population density is 554 inhabitants per square kilometre (1,430 inhabitants/sq mi), and the overall life expectancy is 63.9 years. The population rose steadily from the 1960s until 2006 when the Government of Nauru repatriated thousands of Tuvaluan and I-Kiribati workers from the country. Since 1992, Nauru's birth rate has exceeded its death rate; the natural growth rate is positive. In terms of age structure, the population is dominated by the 15–59-year-old segment (57%). The median age of the population is 21.6, and the estimated gender ratio of the population is 101.8 males per 100 females.

Nauru is inhabited mostly by Nauruans (92.1%), while minorities include those from Kiribati (2.4%), Fiji (2.2%), Australia (1.2%) and other (2.1%). The demographic history of Nauru is marked by several migrations: the area was first inhabited by Micronesian people about 3,000 years ago. The first European to find the island was John Fearn in 1798. Then, the country was annexed by Germany in 1888. The next major population change was when Japanese occupied the island during World War II in 1942. During this time, the Japanese deported several thousands of Nauruans to other islands. In the 1960s, the country gained independence, where the percentage of Nauruans started to increase. The most recent demographic switch was in the 2000s, when the government repatriated several groups of non-Nauruans from the country.

Pius "Mau" Piailug (pronounced /ˈpaɪəs ˈmaʊ piːˈaɪləɡ/; 1932 – 12 July 2010) was a Micronesian navigator from the Carolinian island of Satawal, best known as a teacher of traditional, non-instrument wayfinding methods for open-ocean voyaging. Mau's Carolinian navigation system, which relies on navigational clues using the Sun and stars, winds and clouds, seas and swells, and birds and fish, was acquired through rote learning passed down through teachings in the oral tradition. He earned the title of master navigator (palu) by the age of eighteen, around the time the first American missionaries arrived in Satawal. As he neared middle age, Mau grew concerned that the practice of navigation in Satawal would disappear as his people became acculturated to Western values. In the hope that the navigational tradition would be preserved for future generations, Mau shared his knowledge with the Polynesian Voyaging Society (PVS). With Mau's help, PVS used experimental archaeology to recreate and test lost Hawaiian navigational techniques on the Hōkūleʻa, a modern reconstruction of a double-hulled Hawaiian voyaging canoe.

The successful, non-instrument sailing of Hōkūleʻa to Tahiti in 1976 proved the efficacy of Mau's navigational system to the world. To academia, Mau's achievement provided evidence for intentional two-way voyaging throughout Oceania, supporting a hypothesis that explained the Asiatic origin of Polynesians. The success of the Micronesian-Polynesian cultural exchange, symbolized by Hōkūleʻa, had an impact throughout the Pacific. It contributed to the emergence of the second Hawaiian cultural renaissance and to a revival of Polynesian navigation and canoe building in Hawaii, New Zealand, Rarotonga and Tahiti. It also sparked interest in traditional wayfinding on Mau's home island of Satawal. Later in life, Mau was respectfully known as a grandmaster navigator, and he was called "Papa Mau" by his friends with great reverence and affection. He received an honorary degree from the University of Hawaii, and he was honored by the Smithsonian Institution and the Bishop Museum for his contributions to maritime history. Mau's life and work was explored in several books and documentary films, and his legacy continues to be remembered and celebrated by the indigenous peoples of Oceania.

The Carolinian people (endonym: Refaluwasch) are a Micronesian ethnic group who originated in the Caroline Islands, with a total population of over 8,500 people in the Northern Mariana Islands. They are also known as Remathau in Yap's outer islands. Refaluwasch means "People of the Deep Sea." It is thought that their ancestors may have originally migrated from Asia and Melanesia to Micronesia around 2,000 years ago. Their primary language is Carolinian, called Refaluwasch by native speakers, which has a total of about 5,700 speakers. The Refaluwasch traditionally have a matriarchal society. Most Refaluwasch are of the Roman Catholic faith.

The emigration of Refaluwasch to Saipan began in the early 19th century, after the Spanish reduced the local population of Chamorro natives to just 3,700. They began to emigrate, sailing in small canoes from the Carolines, which had been devastated by typhoons. Being indigenous to a more southern archipelago than the Marianas, they generally have a darker complexion than the native Chamorros.
