4 dic 1845 anni - First unified Tongan state
Descrizione:
On this day, Siaosi Tupou I formally united the islands of Tonga under one kingdom. Siaosi established a strong constitutional monarchy, becoming one of the great powers in Polynesia. While Tonga would become a British protectorate in the early 20th century, it retained much of its autonomy. Tonga was the only Oceanic state to maintain its own monarchy, which survives to this day.
