Best describes government practices in ancient oceania

In Ancient Oceania, back in the year 950 b. C the Tu'i Tonga Empire, or Tongan Empire, dominated the majority of the islands of Oceania; in the beginning kings were able to get rid of the foreign domain and they consolidated the power of the Empire in what today is known as Tonga. Near the year 1200 the Tongan Empire started its expansion, up to approximately the year 1500.

Near the year 1500 many problems within the royalty were unleashed, this weakened the Tongan Empire's figure in the colonies, which found a lot of autonomy from the British Royal Crown and the central power.

In 1799 Tuku'aho was murdered, he was the king of the empire and he possessed the power at the time, this led into a terrible Civil War. With Europe's presence, the Civil War ended leaving the Tongan Empire at the mercy of the British crown,  becoming, at the end of it, a monarchy. Nowadays, even after their independence from the British, some of Oceania's countries are part of the Commonwealth of Nations; this countries still recognize as Head of the State the monarch of the United Kingdom, which today is Queen Elizabeth II.
