Great Britain annexes Tonga Island.

Great Britain is an island in the North Atlantic Ocean off the north-west coast of continental Europe, consisting of the countries England, Scotland, and Wales. With an area of 209,331 km² (80,823 sq mi), it is the largest of the British Isles, the largest European island, and the ninth-largest island in the world. It is dominated by a maritime climate with narrow temperature differences between seasons. The island of Ireland, with an area 40 per cent that of Great Britain, is to the west – these islands, along with over 1,000 smaller surrounding islands and named substantial rocks, comprise the British Isles archipelago.

Tonga Island is a small (0.15 km²) island in Tasman Bay / Te Tai-o-Aorere, off the northern coast of the South Island of New Zealand. It lies within the Abel Tasman National Park, about 1 kilometre (0.62 mi) off Onetahuti Beach. The island has a flourishing fur seal colony, and is surrounded by the Tonga Island Marine Reserve, which was inaugurated in 1993.

May 19 is the 139th day of the year in the Gregorian calendar; 226 days remain until the end of the year.
