Carolinian immigration

The Northern Marianas experienced an influx of immigration from the Carolines (Micronesia region) during the 19th century. Both this Carolinian sub-ethnicity and Carolinians in the Carolines archipelago refer to themselves as the Refaluwasch. The indigenous Chamorro word for the same group of people is gu'palao. They are usually referred to simply as "Carolinians", though unlike the other two monikers, this can also mean those who actually live in the Carolines and who may have no affiliation with the Marianas.

The conquering Spanish did not focus attempts at cultural suppression against Carolinian immigrants, whose immigration they allowed during a period when the indigenous Chamorro majority was being subjugated with land alienation, forced relocations and internment. Carolinians in the Marianas continue to be fluent in the Carolinian language, and have maintained many of the cultural distinctions and traditions of their ethnicity's land of ancestral origin.
