Nauru

Nauru was settled by Micronesians around 1000 BCE.

Nauru was annexed and claimed as a colony by the German Empire.

After World War I, Nauru became a League of Nations mandate administered by Australia, New Zealand, and the UK.

During World War II, Nauru was occupied by Japanese troops.

After the war, Nauru entered into United Nations trusteeship.

Nauru gained its independence from trusteeship.

Nauru accepted Australian aid in exchange for hosting an immigration detention facility.
