Though long inhabited, NMI was originally a scattered group of separate islands. During colonial times, it fell successively under Spanish, German, and Japanese control. After World War II, it was a UN trust territory administered by the United States.

The various major island groups within NMI joined together to form the current commonwealth in 1978. They tried to persuade Guam to join also, but Guam preferred to remain separate. Since 1986, all NMI residents are US citizens due to the special agreement between NMI and the USA.

Commonwealth Cultural Day is a day to celebrate the heritage and the great diversity of NMI. Not only are there several major ethnic groups originally local to the islands, but there are large numbers of Filipino and Chinese residents, among others. And American culture is also thrown into the mix. Many events and displays will highlight one or more of the many cultures that now call the Northern Mariana Islands home.
