Map Tonga

The Kingdom of Tonga (Tongan for "south") is an archipelago in the south Pacific Ocean comprising 169 islands, 36 of them inhabited, stretching over a distance of about 800 kilometres (500 miles) in a north-south line. The islands lie south of Samoa and are about one-third of the way from New Zealand to Hawaii.
Tonga is the only surviving monarchy among the island nations of the Pacific Ocean, as well as being the only island nation never to have been formally colonized.
The islands are also known as the Friendly Islands because of the friendly reception accorded to Captain Cook on his first visit in 1773. He happened to arrive at the time of the ʻinasi festival, the yearly donation of the first fruits to the Tu'i Tonga, the islands' paramount chief, and was invited to the festivities. According to the writer William Mariner, in reality the chiefs had wanted to kill Cook during the gathering, but had been unable to agree on a plan.
