the title is not used on its own. since 1399, the kings and lords of mann were feudal subjects of the reigning king of england, and then of great britain and the united kingdom, who was the ultimate sovereign of the island. this right of 'lord proprietor' was revested into the crown when the isle of man was bought by the isle of man purchase act 1765 and stopped to exist separately. however, for reasons of culture and tradition, the title lord of mann continues to be used. for these reasons, the correct formal usage, as used on the isle of man for the loyal toast, is "the queen, lord of mann".
