Why is "Kingdom of the Isles" trending?

Wikipedia Overview

The Kingdom of the Isles was a Norse–Gaelic kingdom comprising the Isle of Man, the Hebrides and the islands of the Clyde from the 9th to the 13th centuries. It is also called Sodor or the Sudreys, from its Old Norse name Suðreyjar, or "Southern Isles"; as distinct from the Norðreyjar or Northern Isles of Orkney and Shetland. Some of its later rulers were referred to as kings of Mann and the Isles. The historical record is incomplete, and the kingdom was not a continuous entity throughout the whole period. At times it was independent of outside control, although for much of the period the Isles were a Norwegian dependency and its rulers had overlords in Norway, Orkney, or Ireland. At times there also appear to have been competing claims for all or parts of the territory. The islands have a total land area of over 8,300 square kilometres (3,205 sq mi) and extend for more than 500 kilometres (310 mi) from north to south.
