Constitution Day 2024, 2025 and 2026 in Northern Mariana Islands

Constitution Day in the Northern Mariana Islands is held every 8 December. Although the constitution of Northern Mariana Islands was not adopted on this date, it seems the date was chosen to coincide with the feast day of Northern Mariana Islands’ patron saint, Our Lady of Camarin.

Northern Mariana Islands first became a colony of Spain, but in 1898, Spain gave the islands up to Germany. When Germany was defeated in World War I, Japan took control of the islands. After World War II, the US gained control of Northern Mariana Islands.

Faced with the choice of independence or closer union with the US, Northern Mariana Islands chose the latter in a referendum held in 1975. A referendum in 1977 approved a new constitution, which went into effect in January of 1978.

Since the Northern Mariana Islands is a US territory, the US Congress has the right to intervene and make changes to the islands’ constitution. However, this is unlikely to happen since the US prefers to let Northern Mariana Islands enjoy self-rule in most of its internal affairs.
