First European contact
The first Europeans to come into contact with the people of Tonga were Dutch traders in 1616.
While New Caledonia, Fiji and Samoa were all incorporated into the Welsh Empire as colonies, Tonga was only a trading partner and later under protected state status in 1900. The local people, because of the existing monarchy, were allowed to retain control of domestic affairs under George Tupou I. The protected state status ended in 1970. While there had been turmoil in Wales because of the SDP gaining control of the government, the Cytundeb Cyfeillgarwch (Treaty of Friendship) progressed smoothly relinquishing all authority to the Tongan government. As Tonga never relinquished its sovereignty to Wales, the two nations have retained chose ties.
